Last month, we went to the VEX TAIWAN OPEN competition, which is the final major event in Taiwan that is going to determine 3 winners that can qualify for the VEX World Championship. Luckily, we already qualified in the previous PAS-VEX Signature Event. So we don't have much pressure this time.
Just like what we did for other competitions, we held a scrimmage in our lab to prepare ourselves. We definitely learned a lot of strategy and our problems from it.
Since we have already qualified, we chose to use the same robot with some modifications. The autonomous programs and skills strategies were also similar as before.
The first day was pretty easy, there were 1 practice match and 2 qualification matches, along with optional skills challenges.
Unfortunately, for autonomous skills, blocks kept on getting stuck on our robot. We were only able to get 50 points. The driver skills was better, though our robot had unstable match loading speeds, so we didn't have enough time to achieve higher scores, resulting in 73 points. Overall, these are pretty disappointing scores.
We lost the practice match as our teammate had limited scoring capabilities. Though we soon lost again in our first qualification match because we were entangled with our teammate for the first half of the match. Luckily, we secured the final match of day 1.
Day 2 is when the rest of the qualification matches were played. We had a decent schedule and managed to win all 6 matches while getting 5 AWPs. In total, we have 19 WPs, ranking us 4th on the ranking. We ended up choosing 96969Y, forming the 4th seed.
The round of 16 match and the quarterfinal match were pretty easy. However, we soon met 4253S and 4253Z in the semifinal match. The opponents played really well. Luckily, we pulled off a last second score and descore combo, securing the match.
Finally, we faced 66994D and 17022A in the finals. Both were really good teams and really put pressure on us and we didn't have a lot of opportunities to score. In final 2, we even had our intake getting stuck. After losing the 2 final matches, we ended up as the tournament finalists.
Throughout the tournament, we were interviewed twice by the judges. We explained our robot, programming, strategies, and team management. In the end, we were honored to receive the Create Award.
Even if we didn't get the best results, it was definitely still a memorable experience. This time, since we don't have much pressure, we could fully enjoy the tournament.
Congratulations to our sister team, 66994D, along with 17022A for winning the tournament. Also congratulations to 66799X for winning the Innovate Award and 66994T for winning the Design Award.
Overall, huge thanks to 96969Y for being our eliminations partner. Also thanks to our sister teams, we were able to learn a lot from each other throughout the practice matches.
Finally, huge thanks to all of the referees, judges, and volunteers for making this tournament run smoothly.
This is my first year doing the AMC 10. This blog is going to be a documentation of the scores and some future plans.
Before the test, I wrote a historical test every week. I probably did 50 of them. I thought I improved quite a lot, but it turns out that tests from 40 years ago were way too easy that I could even get 150 points sometimes.
There are actually 2 tests this time, a 10A and 10B. I decided to take both so I don't mess up. For 10A, I was super careful and double checked my work. I ended up completing 18 problems and left the rest blank, scoring 118.5 points.
Having a pretty nice score already, I went for speed mode on 10B and wrote a total of 21 problems. Unfortunately, I made quite a lot of mistakes and ended with only 15 correct, resulting in 96 points.
With the score I got on AMC 10A, I got the Certificate of Distinction and qualified for the AIME competition which is a way harder competition.
This year's honor roll of distinciton for AMC 10A requires 136.5 points, which is incredibly high. And the honor roll of distinction cutoff for AMC 12A is 150 points, which is quite unbelievable.
Overall, I'm quite happy with the results, and now I'm preparing for the AIME coming up and possibly the AMC 12 test for next year.
Five years ago, I came to AST with my sister to participate in our first-ever VEX competition. We were inexperienced rookies back then. Five years later, we returned to that same gym—but this time, my sister served as the Head Referee and I was the Match Emcee.
The growth has been incredible. Five years ago, there were only 20 teams. This year, we hosted 25 Middle School and 33 Elementary School teams over two days, including teams that traveled across the sea from Hong Kong. Seeing TAI-VEX and the local community grow so quickly is truly inspiring.
To prepare for the event, I spent time studying the game manual and the specific names of scoring objects. I wanted my commentary to be accurate and to properly represent the teams' complex strategies.
Throughout the weekend, I was able to observe the teams closely. Nowadays, top VEX IQ robots feature complex pneumatic systems, complete sensor integration, and high-level optimizations. But beyond the hardware, I saw the same passion and excitement that we had half a decade ago. These teams spent months building, strategizing, and practicing, just like we did.
To the students competing: Whether you went home with a trophy or not, you have already won because you chose to build and not consume. The skills you learn in VEX aren't just about mechanisms; they are about the engineering process, the ability to work under pressure, and communicating effectively with your teammates. Through successes and failures, you are getting closer to true "Excellence," which is something that can't be found in a plastic trophy alone.
Overall, it was an unforgettable experience. Thank you to AST for the opportunity to be an Emcee—it was truly an honor. Thanks also to the referees, scorekeepers, judges, scouts, field-resetters, and the tech team for making the event run so smoothly. I would have been much more nervous if it weren't for all the friends around.
There are certainly still improvements I can make as an announcer, and I look forward to working on those. Hopefully, in the future, I can find even more opportunities to talk about robotics.
Last month, we went to the PAS-VEX Signature Event. This is the first Signature Event I have been to. Tournament Champions and the Excellence Award winner will qualify for VEX Worlds.
Competition Introduction
This year, there are 72 teams from around the world that participated in this event, including the best teams from Taiwan, Vietnam, China, and other countries.
This event lasts 3 days in total. The first day was relatively low-pressure since there were only practice matches, which is why we chose to do the team interview and most skills matches on the first day. The second day is crucial as 6 qualification matches are played, almost confirming the qualification rankings. Finally, on the third day, 2 extra qualification matches are played, elimination alliances are selected, and the elimination rounds to determine the tournament champions are played.
Pre-competition Preparations
Before the competition, we did a lot of preparation. For 2 weeks, we basically practiced every day to tune our robot and practice driver and autonomous skills. Our robotics lab also hosted a small scrimmage with 11 teams. That was where most of our tournament strategies were developed.
Other than the match preparations, we also prepared decorations and gifts(stickers and cookies). We also familiarized ourselves with the team interview, as it is an important part of the competition.
Day 1
Finally, it was competition time. On the first day, we quickly did autonomous skills: we ran the stable route, and it worked, giving us 74 points. After that, we moved on to driver skills, running it three times. Although a few mistakes were made and we couldn't control the upper center goal, we still ended up with 83 points. This was below our expectations, but still good enough to secure us the 3rd place in skills.
Another important part of day 1 was the team interview. The interviewers were pretty nice, and we introduced basically every aspect of our team, including team organization, the notebook, robot details, programming ideas, and our strategies.
Finally, the 2 practice matches. We won both of them, including a match against a really great team, 50922T.
After the day, we were still busy testing the autonomous skills for day 2 and scouting our teammates and opponents. I slept at 12am, which was very late because we had to wake up at 6am the next morning.
Day 2
For our first qualification, we almost got the AWP but failed to load on the left side, though we still won. In the second match, we successfully ran the Solo-AWP strategy, getting the AWP, but ended up losing the match because one of our intake disconnected, completely preventing us from scoring.
On our third qualification match, our teammate 86254B was really good, and with them, we got an AWP and the win. The fourth match was quite unfortunate as both of our autonomous vehicles were unsuccessful and ended up losing auto. Luckily, we still won the match.
The fifth match was great because we got the Solo-AWP and ended up winning the match. For the sixth qualification match, we unfortunately failed to load on the right side during auto, so we didn't get an AWP, but won the match.
At the end of the day, we were ranked 6th on the qualification ranking, not low but not the highest. So we might be unable to choose our desired teams. At night, we looked at different possibilities and came up with a list of teams to possibly cooperate with.
Day 3
The seventh match was really important. We were against 78181A, one of the best teams. We ended up successfully running the Solo-AWP strategy and getting an AWP, though 78181A did so as well and even outscored us, losing us auto. Luckily, our teammate and I both did well and won the match. This match boosted us to the second ranking.
The last qualification match was very unfortunate since a block from the other side of the field flew here and disrupted our auto, cost us an AWP, though we still won the match. Ending qualifications with us in 2nd place.
Then comes the alliance selection part. Had the 1st place team, 50922T, chosen 66994T, our alliance with 66994T would be broken. Luckily, they didn't do that at the end, and we were able to fight the eliminations with 66994T.
Our strategy worked quite well, as we won the round of 16, quarterfinal, and semifinal matches with pretty big score differences.
Final 1, both of our autonomous ran well, and we won the auto bonus. Our teammate 66994T really dominated the right side long goal and the center goals. We faced some difficulties but ended up winning the left side long goal as well, taking the first final match with a 47-point difference.
Final 2 was a lot trickier. We lost the auto because the autonomous changed the strategy, and our auto didn't work well. The driver period was also really close, but 66994T secured 2 control zones, and we slightly won the left side in the last second. Winning by a narrow margin of 27 points.
Before the eliminations, judges came to us and asked for a second team interview, but we had to play the eliminations, so we didn't have time. After the finals, our second interview was cancelled, and we didn't end up with any judged awards, probably because we already won the tournament. It was really sad since we had spent countless hours writing the engineering notebook, but at least we qualified for VEX Worlds.
Conclusions
After the competition, we made a recap video with the best parts of each match. Feel free to check it out.
Huge thanks to all 3 of my teammates, our alliance partner 66994T, every team we have cooperated with, and every team participating in the event. Also, thanks to the PAS volunteers who made this event possible. Thanks to our coach and our sister teams, who taught us a lot throughout the season. Last but not least, parents who supported their kid to play VEX.
Through the 3 days of intense competition, we have gained a lot more than the award alone. We faced challenges, like the motor disconnection on day 2, or the auto malfunction in the final 2. They really tested our ability to stay calm under pressure. Luckily, we were able to end up winning the tournament.
We still have the Taiwan Open Competition before VEX Worlds, so we still need to keep improving. But I'm extremely happy and grateful for the tournament win.
