Programming and Robot Skills Competitions at Worlds

Since I had two teams that were very competitive in this area, I watched it nearly every time I walked between the Arena and exhibit hall fields.

Robot Skills:

Only a couple of teams turned in 60s (1114a and 2213a). Neither repeated this 60 in the finals in front of the big crowd. No one scored over 60. No Exothermic team did 60, although two had turned in several 60s in practice. There's something about the adrenaline of a real competition, I guess.

My personal favorite team on Robot Skills might be 721, which scored 54 without being able to climb the platform and turn the bonus cube. That's all eight goals and 14 cubes, which is the six on the floor, four on the robot, and four from the autoloader. Pretty darned cool.

Programming Skills:

575 ran their "safe" programming code in their first run and scored 37. 2921 turned in a 30 and another team (sorry for forgetting the team) did 29. Those were the best runs of the day.

Over their mentor's objection, 575 ran their "43" routine in the finals, which is designed to score 43. I don't know what routine 2921 ran, but neither robot did as well in the finals as they did in the dimly-lit preliminary field. When the dust settled, the Kiwis won. (This was probably karmic payback for an alliance captained by Exothermic 418 eliminating them by one point in the Technology division ) 2921 was as good as they looked in the videos -- quite a robot. Did I also mention that they were friendly and professional, too? Nice bunch of robot builders. It would be fun to compete in their tournament. I wonder what it would take to raise that much money?

The highest score I saw an autonomous routine was 575's "43" routine on the practice fields, where they knocked off several 43s. Since both 2921 and 575 were line-followers, the members of 575 think it might have been the more stark lighting on the Arena field that hampered both robots. We'll never know -- but it was a great competition. Thank you, Karthik!

Re: Programming and Robot Skills Competitions at Worlds

We actually managed to score in all 8 goals, all but one cube on the ground, and got onto the platform with 4 seconds left. In retrospect, we could have gotten 55, but we don't believe that 4 seconds will be enough to go for an autoloader. That raises an interesting question about strategy strategy though, because we might have been able to empty an autoloader faster than getting on the ramp, and take one or 2 from the other autoloader to score over 60.

See -- I'm so embarrassed. I didn't see the 54-point run, but that's how a certain Canadian mentor described it to me at the party.

This also means that you would have had 59 points if the bonus cube had fallen just right. Good job.

Re: Programming and Robot Skills Competitions at Worlds

We can't get the bonus cube. We relied on ramping the bot by having it just parked on the lip at the very bottom. We tried for a long time in practice to get our bot over the ramp but all our attempts failed so we left the bonus cube to either our alliance partners or the other teams.

I watched 575 hit 43 on the practice fields many times, I was also really impressed with the attention to mechanical detail on 575.

The exothermic robots are all quite amazing. 418 was one of the fastest scoring robots I've seen in the competition.

Re: Programming and Robot Skills Competitions at Worlds

575 has the best line following code I've seen in competition. Every bot turns to line up with the line and most do it pretty well but 575 is the only bot that I've seen do it smoothly. Every other bot pretty much stops, jerks over and continues while 575 managed to have one side slow down and turn gracefully.

Re: Programming and Robot Skills Competitions at Worlds

I was disappointed that the web cast didn't cover any of the Thursday skills matches. That was one area that I really wanted to watch.

Re: Programming and Robot Skills Competitions at Worlds

I'll get the 575 team to shoot some video of their final line following routine so we can post it on Youtube. I'll also ask if they are willing to post their RobotC source code. On their behalf, thanks for the kind comments.

Re: Programming and Robot Skills Competitions at Worlds

Up there in post #1 I made a mistake -- 2921's alliance defeated 418's in the eliminations, not the other way around. Did I mention I'm taking cold medicine?

It's probably from your body thawing out from last weekend...

Now, its having to re-adjust to the polar climate again.
