We strolled through the lush highlands while our naturalist guide shared intriguing insights. Birds, including finches, often peck at algae or parasites growing on tortoise shells. Interestingly, they appear to leave a marker – possibly guano -to indicate to themselves or other birds that the area has already been picked clean.

A particularly captivating story the guide shared was about how the tortoises may have arrived on the islands. Some have been spotted floating at sea, buoyed by their shells. While saltwater ingestion typically proves fatal, a few may have survived the journey by avoiding it and eventually colonized the islands. Once here, they nested and established themselves over millennia.

Around the ranch, the scenery surprised us with its variety of fruit trees – papaya, passionfruit, and banana trees all grew nearby. These tropical plants thrive in the fertile volcanic soil of Santa Cruz, but we don’t see anything like them where we live.

As we left, a tortoise blocked the road—unhurried and unmoved by the vehicle. We had no choice but to drive around it, but it was kind of comical that it happened.

We felt immense gratitude to have experienced this cruise. The landscapes and wildlife felt remarkably undisturbed. Throughout our time on the islands, we did not see a single piece of litter. Nature here, however, is far from static. Our guide explained how El Niño and La Niña events can devastate local ecosystems. One such event wiped out over 90% of the coral. In ten years, climate shifts may again alter the islands in unpredictable ways.

Weather and ocean conditions were on our side. Due to the Coriolis effect, trade winds and ocean currents in the Galápagos usually flow from the southeast, driving the cool, nutrient-rich Humboldt Current from South America. These currents support a dense food web, influencing where wildlife can thrive and which islands are most biologically productive.

Our itinerary allowed us to see 12 out of the 15 recognized Galápagos species. We missed only the Galápagos albatross, flightless cormorant, and Santa Fe land iguana, which inhabit islands not included in our route. The sites on the islands weren’t arbitrarily chosen. The Galápagos National Park authorities control which vessels can visit which sites on which days, aiming to limit environmental impact and spread tourism evenly.

Each day followed a brisk schedule. Mornings often began at 6 or 7am with breakfast, followed by a midday break and lunch around 12pm. Dinner was served at 8pm. The tempo kept us moving constantly. By the end, we joked that we needed a vacation after the vacation.

Before heading home, we spent one final night in Quito before heading back. At the airport the next morning, we got to try chocolate from República del Cacao. This Ecuadorian company is a certified B Corporation, which means it meets high standards for social and environmental performance, accountability, and transparency. The chocolate itself was excellent, and is a testament to the country’s cacao heritage.

The city of Cairns itself seems to be dominated by the tourism industry. Probably everybody is here to visit these two places. Buskers were present in the streets juggling fiery torches, or doing the statue routine.

The Great Barrier Reef

Our journey began with a snorkelling tour to the Great Barrier Reef in the Coral Sea with Passions of Paradise. After a two-hour boat ride to Hastings Reef within the GBR, we were grateful for the seasickness pills provided, which kept nausea at bay. The day was pleasantly warm, with temperatures in the mid-20s Celsius, providing comfortable conditions above water. However, as we prepared to enter the water, we found that even with wetsuits on, the ocean felt surprisingly cold. The tour catered to all skill levels, from non-swimmers to experienced scuba divers, ensuring everyone could enjoy the underwater spectacle.

The reef revealed an underwater world. Colourful coral formations stretched as far as the eye could see, home to a diverse array of marine life. We felt fortunate to visit the Great Barrier Reef at this time, aware that climate change poses a significant threat to this delicate ecosystem. We spotted several species of coral, which I think included staghorn coral, brain coral, and acropora (but I’m no expert).

Schools of fish darted around us, including the iconic clownfish, which we were surprised to find were much smaller than expected (the movie Finding Nemo makes them seem so much larger). These iconic fish, have a symbiotic relationship with their host anemones, and rare venture more than a few metres away.

Other marine creatures we encountered included starfish, and a sea cucumber. The highlight was spotting a giant clam, its massive shell partially open, revealing the colourful mantle within. The mantle is the fleshy, visible part of the clam when its shell is open, and often has a blue-green coloration, which are due to symbiotic algae living in their tissues. The presence of a giant clam is an indicator of a healthy reef ecosystem, as these animals are sensitive to changes in water quality and temperature.

The Daintree Rainforest

The next day, we continued with a trip on the Kuranda Skyrail, a series of gondolas that provide a bird’s-eye view of the Daintree Rainforest canopy. This ancient rainforest is estimated to be over 180 million years old, making it one of the oldest continuous tropical rainforests in the world. The Coral Sea to the north provides abundant moisture, while the Great Dividing Range mountains to the south force air to rise, cool, and condense into rainfall to support the lush tropical rainforests.

Our guide shared insights about the forest’s ecology. The rainforest canopy is so dense that it creates a challenging environment for new trees to grow in the understory. Saplings must wait for larger trees to fall before they can access enough sunlight to thrive, a process that can take decades. We also learned about the cassowary, a flightless bird that resembles a modern-day dinosaur. Too bad we didn’t spot one though, but there was a life sized model for us to see.

One of the most intriguing plants we observed was the basket fern. This epiphytic fern grows high up on tree trunks and branches, forming a nest-like structure that collects falling leaves and debris. The decaying matter provides nutrients for the fern, allowing it to thrive without soil. Another fascinating plant was the wait-a-while vine. This climbing palm has long, flexible stems covered in sharp, backwards-facing spines. These barbs allow the vine to hook onto surrounding vegetation as it grows, eventually reaching the canopy where it can access more sunlight. Eventually it might even strangle a taller tree to death. The guide also introduced us to the powder-puff tree, an plant known for its striking red, fuzzy, spiky ball-like flowers, which attracts various pollinators, making it a vital part of the ecosystem. I was really impressed at how different plants took over different biological niches.

Kuranda Koala Gardens

Our rainforest adventure was complemented by a visit to the Kuranda Koala Gardens, where we had the opportunity to see Australia’s iconic marsupials up close. We were surprised to learn that their fur isn’t uniformly grey – their butts are actually a light beige colour.

The gardens also housed other Australian wildlife, including crocodiles, kangaroos, and wallabies. We spotted a charming little yellow bird in a hanging nest (olive sunbird). Outside the gardens, we also saw a ulysses butterfly. Despite what all the pictures show, they actually have wings that are blue on one side and brown on the other.

Culinary Adventures

Our culinary experiences in Cairns were all hits except for one disappointing skewer meal that left much to be desired, with oddly mushy grilled corn. However, we also enjoyed some exceptional dining experiences.

At the Ochre on the Esplanade, we sampled some unique Australian meats. From the left to right, the emu in the emu wonton was dark and rich, reminiscent of beef but with a gamier taste. Next was the kangaroo, but it wasn’t as good as the one in Sydney. The crocodile meat on the other hand was lean and had a texture similar to chicken, with a slightly fishy flavour. The last item was the usual smoked salmon.

One of our most memorable meals was at Salt House, where we dined while watching the sun set over the water. We enjoyed succulent scallops and barramundi.

The highlight of the meal was the MB4+ Black Onyx Grain Fed Scotch Fillet. MB4+ refers to the marbling score of a steak used in Australia beef grading systems and goes from 1 to 9, with 9 being the best. A scotch fillet is essentially the same cut as a ribeye steak, coming from the rib section of the cow. However, while a ribeye typically includes the cap (or spinalis dorsi muscle), a scotch fillet often has this removed. It’s similar to the French entrecôte, though the exact cut can vary slightly. Despite a marbling score of 4/9, the marbling on this particular steak still tasted excellent, resulting in a flavourful and tender dining experience that would be hard to match at a similar price point elsewhere.

Our time in Cairns offered a nice blend of natural wonders and culinary discoveries. From the underwater marvels of the Great Barrier Reef to the ancient beauty of the Daintree Rainforest, and from cuddly koalas to unique Australian cuisine, Cairns provided an awesome experience of Australia’s tropical north.

Circular Quay

The Sydney Opera House, with its distinctive sail-like design, is not just an architectural marvel but also a UNESCO World Heritage site. Completed in 1973, this masterpiece by Danish architect Jørn Utzon has become synonymous with Sydney’s skyline. Its unique expressionist modern design features a series of precast concrete “shells” that form the roof structure, creating a striking silhouette against the harbour waters.

Adjacent to the Opera House stands the equally impressive Sydney Harbour Bridge. This steel bridge opened in 1932 and remains the world’s largest steel arch bridge. There is a tourist attraction there where people can walk along the arch of the steel beams (people are tethered for safety).

Souvenir shops lined the waterfront selling stereotypical Australian souvenirs like kangaroo and koala plushies. They also sell a lot of hats, which I recalled that those are also very stereotypically Australian thanks to people like Steve Irwin, the Crocodile Hunter.

The Royal Botanic Garden

Established in 1816, this green oasis in the heart of Sydney is Australia’s oldest scientific institution. The gardens showcase a diverse collection of native and exotic plants, especially ones that are not present where I live. One of the standout flora was the Bird of Paradise plant, native to South Africa but thriving in Sydney’s climate. Its vibrant orange and blue flowers, resembles an exotic bird in flight.

I also encountered a variety of birds that I don’t usually see (I’m told some of them are garbage birds though). One amusing incident involved birds in the trees nearly missing some oblivious bystanders with their droppings (and oblivious even after the fact).

The Royal Botanic Garden proved to be more than just a green space; it was a living museum of biodiversity, a sanctuary for urban wildlife, and a peaceful retreat from the city’s bustling energy.

Barangaroo

We also took a walk through a nearby neighbourhood called Barangaroo. This area, named after an influential Aboriginal woman from the early colonial period, has undergone a remarkable transformation from a disused container terminal to a vibrant waterfront precinct with a mix of parklands, cultural spaces, and modern architecture.

Walking through Barangaroo, with its urban renewal, reminded me of strolling through Yaletown and Olympic Village in Vancouver, offering harbour views and an urban atmosphere.

Manly Beach

People also associate beaches with Australia. Close by to Sydney is Manly Beach. This popular stretch of golden sand is renowned for its excellent surfing conditions and laid-back atmosphere, and it also has an amusing name. According to Capt. Arthur Phillip, who named the beach, wrote of the indigenous people living there, “their confidence and manly behaviour made me give the name of Manly Cove to this place”

Birds also hang out in the nearby trees, chirping so loudly, they sounded like bats. It almost makes it scary to even approach the tree even though I know they’re just birds.

Manly Beach encapsulates the quintessential Australian beach culture – a perfect blend of natural beauty, outdoor activities, and relaxed coastal living.

Culinary Adventures

Sydney’s culinary scene proved to be quite delightful and exotic. In the spirit of trying local specialities, I sampled grilled kangaroo at The Meat and Wine Co. This lean meat, similar in texture to beef, offered a milder flavour with a subtle gamey note. It’s a unique protein that reflects Australia’s distinctive fauna and culinary traditions.

Another local delicacy at The Meat and Wine Co I had the pleasure of tasting was barramundi, also known as Asian sea bass. This white-fleshed fish is prized for its sweet, buttery flavour and firm, moist texture. When cooked, barramundi offers a delicate taste that’s less “fishy” than many other species.

Dinner with friends I know in Sydney at Bar Totti’s was another culinary delight. This pasta place came highly recommended, and it did not disappoint. Luckily, we had a reservation because by the time we arrived, there was a crowd of people waiting at the door. This trendy eatery has earned a reputation for its exceptional pasta dishes cooked al dente with flavourful sauces that complement rather than overwhelm the pasta itself. It’s also renowned for its baked bread, a signature item on their menu. The bread is served fresh out of the oven, airy and fluffy on the inside with a perfectly crisp crust. It’s also accompanied by a variety of dips and spreads.

I also found myself developing a newfound appreciation for salads, discovering that they can be far more than just a boring mix of greens. The city’s cafes showcased salads bursting with variety – multiple types of leafy greens, complex carbohydrates, diverse proteins, and flavourful dressings that elevated the humble salad to a satisfying meal.

Overall, I was quite impressed by Sydney’s food scene.

For one reason or another, I never made it out to Saint Joseph’s Oratory the other times I visited. According to my cousin, “it’s one of the best free attractions in Montreal”.

Saint Joseph’s Oratory is Canada’s largest church, and it enshrines a statue of Saint Joseph within it, I wasn’t able to take a good photo myself of the the oratory in all its beauty, so here’s one from Wikipedia.

We weren’t allowed to go inside the main nave (where the people sit in church) of the basilica since it was closed for an event. But we were able to go to the Crypt Church on the floor below.

The statue of Saint Joseph is located in the Votive Chapel. People all over come here as a pilgrimage to pay their respects.

Since Saint Joseph’s Oratory is located on Mont Royal, there is a viewpoint nearby to look into the city.

Someone had some fun at the nearby chalet!

A short hike from there was the Mount Royal Cross. The temperature was only slightly below freezing, so it wasn’t as cold as I expected Montreal to be. I was told that it’d get much much colder in January and February.

The next place we went to was Old Montreal. It was pretty dead, even for a Sunday afternoon. It makes sense since I’m way past the busy tourist season! In the summer, all the restaurants set up patio seating outside, but it was too cold to do any of that in November.

Lastly, I went to the Underground City. Like a lot of cities that get really cold, the city has built a network of underground tunnels so that people can avoid walking outside in the cold winter. Some parts of it are actually really nice!

A piece of the Berlin wall appears in the most unlikely of places..

One of the places I wanted to go on this trip was the Biodome, which tries to recreate different ecosystems in the world to display various plants and animals that live there. Unfortunately, it doesn’t reopen until summer 2019.

Fun fact: Hawaii is not part of North America, but rather Oceania.  Already on the flight in, Hawaii already looks beautiful.

On the North Shore of the island, sea turtles sometimes just chill out on shore.  They are endangered because people wanted to eat them and use their shells for superstitious medicine.  It is illegal to touch them and there is a fine for it if caught.

Here’s a picture of our nice rental car – a BMW 535i.  Notice how there isn’t a front license plate (not legal)

Parts of Oahu’s coastline has lots of these oddly shaped rocks (possibly some volcanic rock?)

There’s also cool rock formations like this one at Laie Point.  We saw people here fishing, and jumping into the water from the cliff side – looks dangerous, but super fun.

For hikes, not many people know about the Puu O Mahuka State Monument, where there is a semi-hidden path that leads to a really good view of Waimea.

There’s also the Pillbox Hike near Lanikai beach, which is a bit more touristy, but the view up there is really nice too.

Another well-known hike is the Diamond Head hike, which starts at the base of a crater all the way up to the top edge of it.  From there, there is a good view of Waikiki and the surrounding area.

Another hike, called the Makapuu Point Lighthouse Trail is another hike to see Oahu’s natural beauty.  At some parts of the hike, the mountain blocks the wind completely, so on a hot day, there is no breeze for cooling down, which makes this hike a little less enjoyable.

For a night view of Honolulu, we headed up to Roundtop Drive

This is the best food in Hawaii.  It’s called Poke.  It’s essentially raw fish with spices on it – absolutely delicious when it is fresh.  The ones here are from a place called Fresh Catch.

Of course, there is also Pearl Harbor, the site where the Japanese attacked the United States in 1942.

The USS Arizona Memorial is built on a sunken battleship, the USS Arizona.  Even now, pockets of oil still bubble to the surface.

At the Polynesian Cultural Center, people can learn about the Polynesians and experience their culture through stuff like dance performances.  Too bad I couldn’t get a picture of their actual theater performance, where they did crazy tricks with sticks lit on fire.

There is the stereotypical Luau, which is a buffet with a dinner performance (with more fire involved).  There’s good food like kalua pig, poke, salmon, chicken, etc.

One thing that really surprised me about Hawaii is the amount of wild chickens everywhere.  I even got woken up in the morning by a rooster’s call in the morning.

Other things to do in Hawaii that I recommend:

• Trying garlic shrimp from a food truck (like Fumi’s)
• Drinking out of a coconut (really stereotypical, but I’ve always wanted to try this!)
• Drinking an Otai (coconut and mango drink)

Things that I do not recommend:

• Driving too fast.  Police are EVERYWHERE and it is impossible to get away with breaking traffic rules.  I learned this the hard way.

Since members of the church are encouraged to do missionary work, some of them are assigned to Temple Square to work as tour guides. In the Visitors’ Center, there were many of them from different countries and the tour guides we got happened to be from Canada and USA.

The guides took us to the top of the North Visitors’ Center to show us an 11-foot tall statue of Jesus (picture from Wikipedia). While up there, the guides played a short audio clip about Jesus’s purpose and told us about their beliefs. Even though I’m not Christian, it was clear that they were quite devout and dedicated and such qualities are definitely admirable.

Next, the guides took us to the Salt Lake Tabernacle to see the pipe organ.

Then the guides asked us, “how many pipes do you think there are?” Me, not knowing anything about organs, merely counted the ones I saw on the surface and naively said, “maybe about 30”. It turns out I was off by several orders of magnitude. The answer: 11,623.

The building was built to house meetings for the church and was used for the LDS General Conference, but the church grew so large, that the occupant capacity of the building was exceeded. After that tour ended, we visited the newer and larger conference center.

We got a tour of the inside and it was massive with 21,000 seats. We were told that to play the church organ, the organist would have to have a PhD in that field.

The roof of the building had a beautiful view of the Temple Square and had a nice garden full of many varieties of plants.

Lastly, there is the temple itself. Unfortunately, it is not open to the public as it is sacred and there are strict entrance requirements. But at least it looks nice on the outside!

That concluded our tour of the Temple Square in Salt Lake City and then we made our way to the airport and flew back to Vancouver.

Flying to Mexico City

When we got to Dallas Airport, we had a stopover of few hours, so we decided to have some Texan steak – or at least as Texan as we tried to get without leaving the airport.  We ended up at TGI Fridays.  It was the first steak that I’ve had in a long time, and I definitely could use another one.  The steak even came with “Jack Daniel’s Sauce”, which made it that much better.

After eating, we met up with two others on the team who had flown from San Jose and Toronto.  After a four hour flight to Dallas, and other few hours of stopover there, we had to fly for another two and a half hours to get to Mexico City.

As my friend said, “it’s like China happened”.  The Benito Juárez International Airport was probably the most disorganized airport I’ve ever seen.  It’s as if every single flight landed at the same time.  The lineup to grow through customs took at least forty-five minutes.  During this whole time, everyone was tired and wanted get their sleep.  A lot of the people on the team hadn’t slept the night before (rather than sleep 2 or 3 hours to wake up early for the flight right?).  While in this lineup, we saw a couple of other RoboCup teams landing as well (Skuba, MRL, among others).  After finally getting through customs and a security check, we got a ride to our hostel via transportation that we organized with the hostel prior to our departure.

Hostel Mundo Joven Catedral

The hostel we stayed had very nice staff that really cared about making its guests feel safe there.  It’s a common feeling among travelers to think that Mexico City is definitely not one of the safer places to travel to.  To combat that, the hostel had its own security guards, security cameras, and they even called legitimate taxi’s for its guests.  They even told us which direction to walk when leaving the hostel to avoid going to the shadier parts of town.  Furthermore, it was situated in the historic center of Mexico City, within walking distance of the Metropolitan Cathedral of the Assumption of Mary of Mexico City and the Plaza de la Constitución.  From some of the rooms at the hostel, there was a nice view of the cathedral.

Work Day

We spent the next day working on the robots to make sure none of the mechanical parts had been affected during the flight from Vancouver.  We had packed all the robots in a regular suitcase with packing foam all around it to protect it.  Looking over the mechanical parts, everything was in order.  The main things we had to fix were tightening screws, adjusting the wiring etc.  The software team had very little to do because they’ve written all the code they could, and just needed robots to test with.  The electrical team on the other hand, toiled tirelessly to troubleshoot all the boards and make sure they were all functioning properly.

RoboCup Begins!

We arrived at the competition venue, the World Trade Center at 8 AM to find a slew of other teams patiently waiting to register.  After probably an hour long wait, we all finally moved in and set up our work places.  When we looked at the field the robots would be playing on, we noticed that the organizers hadn’t yet set up the cameras yet (required for the robots to “see” where they’re going).  This meant that no teams could test.  Teams that were ready could only wait until the organizers got those set up.  Because of this delay, the games had to be delayed as well.  This gave us more time to get the robots ready.  For the next little while, we were the first team to arrive and the last team to leave everyday.  The electrical team needed all the time they could get to finish everything.

Because we had already finished most our maintenance work the day before, there wasn’t a whole lot we could do.  The electrical team had to continue working on their stuff to get as many robots ready as possible.  For the next day and a half, we let the electrical team do their work and we’d help them along the way by replacing parts that were broken (encoders and such).  Otherwise, there wasn’t much we could help with.

Food for the next Week

When we got hungry during the competition, we did a little bit of exploration to find food.  Eventually, all the teams wound up at the same shopping mall for food.  There was a supermarket downstairs to buy water and a food court upstairs with a variety of foods.  We went to this mall pretty much everyday for as long as we were at the World Trade Center.  One day we’d try Mexican food, other days we’d try plain-old hamburgers and other days we’d try even Chinese food (at least the white person’s interpretation of it).  It wasn’t really healthy for us, but we figured it was only for a week.

For dinner, most teams ended up ordering pizza from the nearby Domino’s.  We ate it so much that everybody got sick of having pizza.  Sometimes, we’d have dinner with other teams at our hostel restaurant so we could get to know them a little bit better.  After all, the competition is more about mutual learning and robotics advancement rather than about winning.

Let the Games Begin

Because our team wasn’t that ready to begin with, we had to forfeit our first game against the Immortals from Iran.  By the time we got three robots up and running, we played against the RoboJackets from Georgia Tech.  They only fielded five robots out of the total six.  For most of the game, both teams played pretty evenly, despite their two-robot advantage.  All was going well until one of the opponent’s robots chipped the ball that hit the top of one of our robots, bounced off and rolled into the goal.  In that particular situation, the referee had called an “indirect free kick”, meaning the shot, even if it went in the net, would not count.  But unfortunately, that rule was not applicable because it hit off of another robot.  It was an unlucky goal for us, and we definitely could not score a goal to tie up the game.  We ended up losing one-nil.  For the next few days, we kept complaining about that goal.

In our third game, we played against RoboFEI from Brazil.  There were so many good scoring chances in this game from both our teams that made this game so intense.  Even though we were only watching machines play, everybody cheered them on.  We had four robots on the field this game and they all worked like a charm.  The mechanical system, electrical system, and the artificial intelligence worked so well together.  It was a great feeling for everyone on our team – to see our design work.  After almost a year of hard work, this was it.  We saw our robots move, intercept balls, shoot on the goal, etc.  A lot of the robot shortcomings from the North American Open were also dealt with, such as the problem of the break beam sensors not working, and the robot not moving accurately on the field.  When we scored, we cheered so loud that every single person in the room could hear us (there were probably about 1000 people in that room).  We all got an immense feeling of satisfaction in seeing our working robots score their first goal.  A few minutes later, the other team scored a goal.  It didn’t matter to us, we were still high in the clouds in terms of our mood.  The game ended 1-1.  Despite the tie game, everyone on the team was so happy in seeing our robots work, it didn’t matter what the result was.

This was a great morale boost for the team because for our forth and last game, we played against BRocks from Turkey.  This time, we had our full fleet of robots.  We played our first six on six game.  Yet again, we saw our robots work.  Nothing broke down during the game and everything just worked.  It was quite rare for us to just put our robots on the field and have nothing go wrong.  At one point, our robot shot the ball into the opposing robot and a piece fell off of it.  We knew our design worked when stuff like this happens.  This game was less intense for us than our previous game, but we did end up winning.  That put our record at 1 win, 1 tie, and 2 losses – a total of 4 points.  Unfortunately, this wasn’t enough for us to advance to the next round of the competition and as a result we finished 13th out of 20 teams in the league.  Not so bad for having zero working robots when we got to Mexico.

After the official games, we played a couple friendly games with other teams.  The first game we played was against the Mannheim Tigers.  The game was going well, until we found problems where some of the screws on the robot weren’t tightened sufficiently.  As a result, things well off the robot when we played.  It was quite embarrassing to see.  At least it was only  something minor like putting in a screw, and not something major like a design problem.  In our second friendly game, this time against ER-Force from Erlangen, we found some electrical parts frying randomly on the board, which wasn’t good either.  Out of six working robots, we now had three – still a net gain I guess.

After we were done playing, we watched the other teams play for first place.  From watching their games, it was clear that they played on a way higher level than we did.  Everything that their robots did were way better than ours.  Shooting was faster, chipping went further, robots moved faster, kicks were more accurate, etc.  Everything about their robots was just better.  There is definitely a lot we could learn from these teams.  The final winner of this year’s competition ended up being Skuba from Thailand, who beat ZJUNLict from China.  Both teams analyzed each others strategies for days, but only one team could come out on top.  And now for the fourth year in a row, Skuba remains the undefeated winner of the competition.

Other Leagues in RoboCup

During our idle time, we walked around the other rooms to see how the other teams were working.  RoboCup has many different competitions under its name, while our Small Size League competition is only one small part of it.  Leagues range from soccer robots, rescue, simulation, to even home care robotics.  In the home care robotics league, the competition involved a robotic navigating through a mock house to perform certain chores such as picking up objects to hand to people, speaking and hearing instructions, etc.  It was an admittedly difficult task to do for these robots, but many teams were quite successful at it.

Accidents Happen

Just like in the North American Open, there was yet again another accident involving batteries.  Except this time, nobody noticed and the whole battery lit up in flames.  Somebody just yelled “fire, fire!” and started trying to pat it down with something.  Knowing that I was too far away to do anything, I just took out my camera and snapped a picture of the whole thing.  Eventually, someone just poured lots of water over it to put our the fire.  In retrospect, that might not have been a good idea since water in an electrical fire is not really a good thing.  Nobody got hurt though, which is good.  Afterward, the organizers didn’t let us charge batteries nearby our work space anymore.

Some Design Shortcomings

Knowing that our ball kicker would be able to withstand impacts of the ball, what we had forgotten to analyze was how well the kicker would hold up if it hit a object fixed to the ground.  We found out the hard way at the competition after a few games when we discovered that our robot kicker head was bent out of shape.  We also had a lot of turf buildup inside the robot that was enough to slow down the wheel during the game.  This turf had to be cleaned out after every match.

For the kicking mechanism, the robot uses a solenoid/plunger mechanism.  Activating the coil would cause the plunger inside the core to move quickly to hit the ball.  A rubber band secured to the end of it would allow the plunger to return to its initial position.  The problem with this setup was that the rubber band would easily break and had to be replaced after every game.  When we took out the rubber band, we could always see cut marks along it.  In another instance, a chipper solenoid on a robot almost popped out.  It’s not really clear why this happened at all, but it could have been a screw that was not very tight to begin with.

RoboCup Closing

To close the competition, there was a soccer game where humans played against the middle size league robots.  It was pretty funny to see the robots struggle to take the ball away from people who could handle the ball way better.  At the same time, the humans were really scared of the robots since if a human ever got hit by the kicker head from the robot, it would break bones.  The robot goalie however, proved quite competent in blocking shots – better than the human goal from what I saw.  Or maybe the human goalie wasn’t trying very hard.  I’m not sure who won the game since I didn’t watch the whole thing, but it was still really interesting to see.

Afterward, all the teams packed up their things and waited for the closing banquet.  At the closing banquet, they served a standard meal for everyone.  It was a really good chance for teams to celebrate their achievements and finally relax a little bit after the competition.  Everyone deserved a rest after all of that.

First Real Tour of Mexico – Teotihuacan

After the competitions ended, most teams stayed an extra day or two to see the sights in Mexico City.  The organizers of the Small Size League were nice enough to organize a tour for everyone the day after the competition ended.  Most of the SSL teams went with us to the Aztec pyramids in Teotihuacan.  The tour first showed us how their predecessors used different plants and minerals to make tools such as knives and sewing thread.  That part was interesting at first, but I think what a lot of us really wanted to see were the pyramids.  Afterward, the tour guide led us to the gift shop.  For some reason, most of the people were so interested there, it took about an hour for everyone to finish so that we could move on with the tour.  After the gift shop, we finally made it to the pyramids.

After walking up and down the pyramids, we had lunch and went back to Mexico City to see the Basilica of Our Lady of Guadalupe.  This was one of the most visited Catholic shrines in the world.  But because I had already visited so many churchs and cathedrals from my tour around Europe, this part of the tour was less interesting for me.

Historic City Center

The team would fly back to Vancouver on the day after visiting the pyramids.  But before leaving, we made sure to visit the Metropolitan Cathedral of the Assumption of Mary of Mexico City and the Plaza de la Constitución.  In the plaza, hung a giant flag of Mexico.  This is where the city center used to be, at least during the 19th century.

Going Home

After 10 days in Mexico, we all longed to go home.  It had been a long week – full of stress, adrenaline pumping excitement and overall a good experience.  But after all that, we were ready to go.  We flew out in the afternoon from Mexico City.  Apparently, at around the same time that we were at the airport in Mexico City, three cops had been shot to death.  While we were there though, we didn’t hear anything of it.  We safely arrived in Dallas for a brief stopover and arrived back in Vancouver at about 8:30 PM, just in time to go home, wash up and go to bed.

The day after my friends and I went to Berchtesgaden, we went to Wilhelma, the Stuttgart Zoological Botanical Gardens.  It has a fancy name, but it basically is a zoo with exhibits for other life such as plants and insects.

Seeing as how I’ve never been to a zoo before (at least I don’t remember), but I have been to the safari and Biodome in Quebec, this trip to the zoo was quite interesting for me.

To get in, my friends used their student ID’s to get a student discount, but I however, didn’t have my ID anymore since I lost it.  I ended up using a letter of enrolment from my university to prove my student identity.  The best part about doing that was that I managed to communicate what I wanted speaking only German.

When we entered, we looked on the park map to see the best route we could use to see everything, but since the zoo had a plan for that, we decided to follow it.  It had a strange system of showing visitors which path to follow.  The intended path was marked by a yellow elephant with a direction to walk in and the path back to the beginning was marked by a blue elephant.  We tried our best to follow this route, but we didn’t really manage too well.  We still ended up diverging from the path.

Our first destination was a group of greenhouses that had plants from all over the world, but in particular, we saw a lot of cacti.  For some reason, the people at the zoo really like cacti.

Moving on, we saw a flock of flamingos just chilling there.  They didn’t really do much except just stand there and drink water.  We did get to see some flamingos standing on one leg just like what a lot of animal documentaries show.

Moving further along, we saw a peacock just wandering around the park.  We didn’t get to see it open its tail, but it was still pretty cool to see one live.  It kept trying to move away from the little kids that kept trying to chase it, but I still got a picture.  Apparently, according to Wiki, the umbrella term for the animal is “peafowl”, while the name “peacock” only refers to the male peafowl.

While we walked around the zoo (while deviating from the yellow elephant path), we came across a lot of signs that pointed to the “Titanenwurz”, which in English means “Titanum”, the tall and large plant local to Sumatra that has a smell similar to rotting corpses when it blooms.  Apparently, this zoo holds the world record for the tallest Titanum plant during blooming.

Moving further along, we ended up indoors and the only lights that illuminated the inside were a set of blue lamps inside a display.  In the display, there were bats.  Some of them hung there while others flew around randomly.  They didn’t shriek or make any noises for echolocation or anything like that though.  They were also bigger than I thought they were.

Moving further along, we came across plants that reminded me very much of Pokémon.  I guess the Pokémon were modeled after this plant.

The next part was the best part of the zoo: monkeys.  The monkeys here were really small and all they did was jump around from one branch to another.  While I was taking pictures of them, I moved my camera a little too close and it tried to grab my camera strap.  I felt its fingers brush against my hand before I moved my camera away.  While watching the monkeys, I kept hearing little kids yelling “baby monkeys!” in German.

There were other monkeys too, but those weren’t as interesting because they mostly just sat around eating (especially the apes).  Next, we moved on to see the more exotic animals – the big cats.  For some reason, these animals weren’t really in the mood to do anything.  Instead of sitting around like the monkeys, the big cats pretty much were just lying there.  None of the cats did anything special except the leopard when it got up to eat.

Next we saw other exotic animals like okapi (never even heard of this animal before) and various African/South Asian animals.  It was pretty cool to see an elephant duck down to grab food with its nose to eat.  I’ve never seen anything like that before.  The giraffes were cool too, but they weren’t quite as tall as I expected, but maybe these ones are of a different species or are just younger.  The rhino wasn’t very cool either since the zoo staff got rid of its horn, but maybe it’s safer that way.  But then again, a pissed off hippo could probably destroy a rhino.

The zoo also had some less interesting animals such as cows, chickens, lambs and various other farm animals that people eat on a regular basis.  This was probably the most boring part of the zoo.  These animals smelled absolutely terrible and weren’t very interesting to look at.  The cows here were only penned in by a electrified rope (which my friend touched and received quite a nasty shock – that was quite hilarious).  The next bunch of animals were saw were the bears.  Seeing the bears promptly reminded me of Stephen Colbert’s famous quote, “bears are godless killing machines!”  They do look quite menacing, except for the polar bear, who didn’t really feel like doing anything at all.  Maybe it was too hot or something.

The zoo even had some animals from Australia like crocodiles/alligators (I know the difference between them, but I don’t know how to “see” the difference) and kangaroos.  We didn’t get to see the kangaroos up close because some zoo personnel were cleaning the area at the time.

At this point, I realized that the zoo was a lot bigger than I thought.  We had already walked around for about 3 hours but there was still so much more to see.  Here are some more animals we saw.

Here comes the nastiest part of the exhibits – the insects.  Here they showed a lot of just purely disgusting pests like cockroaches, although, there were some cool ones like the insect that is able to disguise itself as a leaf.  They camouflaged themselves so well that it was almost impossible to see them.  However, on the more pleasant side, butterflies are always nice to see.

To finish our adventure at the zoo, we saw penguins.  I had no idea that there are some species of penguins that can survive such warm temperatures (or maybe all of them can – I don’t know).

After about 5 hours of walking around the zoo, we saw almost everything.  By now, our legs were very tired and we didn’t really have the energy to walk around anymore.  Instead, we did have enough energy for video games because afterward, we all went back to my flat for a good Team Fortress 2 (thanks to Valve for making this game free to play) LAN party.

Seeing that I come from a family where my mom does almost all the cooking, I never learned how to cook all that well.  Yes, I currently live on my own in Germany, but I don’t need to cook that well.  The reason is that for breakfast, I cook the easy breakfast food like eggs, bacon, and sausages.  For lunch, I eat at the cafeteria at work.  All interns get a discount there.  Lastly, for dinner, I usually just eat a sandwich.  I keep my dinners light since I sleep quite early and it wouldn’t make sense for me to go to sleep right after I eat a huge meal.  Although I got every meal covered, I need a little variety.  In a way, I started to learn how to cook.  For starters, I figure cooking potatoes is a nice way to start.  I guess I took quite the plunge when I decided to live on my own without knowing how to cook.

All I had to do was peel the potatoes, cut them up into little blocks and throw them on a frying pan.  I know some people use onions, but I’m not a fan of them.  Sounds straightforward, except I had never peeled a potato in my life.  However, I’m not that clueless in cooking and I knew that I needed to use a peeler.  I took the peeler out and got started.  Either the peeler had a dull blade or I just lacked peeling skill, but for the life of me I could not peel the potato.  I quickly gave up on the peeler and looked for a knife.  I remembered that’s how I peeled apples in my childhood, when I was curious about those things.  Unfortunately, the only knife I could find was a giant steak knife.  Better than nothing I guess.  I got started peeling the potato skin, while carefully ensuring that the skin stayed together as one long strip during the peeling. Peeling with a giant steak knife just didn’t really cut it (lame pun I know).  I took out my Swiss Army Knife instead.  Holding the knife with my right hand and the potato with my left, I began to peel the potato.

However, due to a pure lack of skill, the knife plunged into the tip of my left index finger.  The knife probably went in about a few millimeters before I was able to react.  With blood gushing out nonstop, I went and looked for some tissue to soak up the blood and stop the bleeding.  While this happened, I refused to lose to this tiny potato.  I continued to peel the potato while trying to stop the bleeding at the same time.  A minute later, I finished peeling the potato and began to fashion a tourniquet using the tissue, cloth for eyeglasses, and a rubber band.  I wrapped the tissue around the wound, then tied the cloth into a knot around it.  Fearing that the cloth wouldn’t be tight enough, I put a rubber band around it.  Fifteen minutes later, I managed to stop the bleeding. 

Undeterred by the injury, I continued to peel the rest of the potatoes and continued with my plan.  I cut up the peeled potatoes into little chunks and threw them on a frying pan with some butter.  A while later, I finished cooking the potatoes and began to enjoy them.  I guess if life gives me potatoes, I should cut them up and throw them on a frying pan without injuring myself.
