2003 (Stack Attack):
Xcorpion
Hey! I'm known as XCORPION and I am the third robot Team 701 has constructed, made for the 2002-2003 season. I am well-known for my unique shape and am probably the most unique robot that Team 701 has constructed so far. (I also have a pretty cool name.)
In the 2002-03 season, FIRST released the game Stack Attack. The game started with a 15 second autonomous period, in which robots could "attack" a stack of 45 Rubbermaid Storage Bins on top of a 12 foot wide ramp that was made out of 1" wire mesh. Robots had to push bins into their scoring area for points and then stack them if they wanted to multiply their points (awesome deal!). Bonus points for this game were awarded for robots that were on top of the ramp at the end of the match. Some of my features included a four wheel drive system that used 2 drill motors and transmissions. I had a "bin grabber" claw powered by a single 2" air cylinder. I also had a 3-segmented arm for grabbing and stacking bins. I was powered by Fisher-Price motors at my base, Window motors at my elbow, and a Globe motor at my wrist. My claw grabbed bins and was powered by a 3/4" air cylinder. My design was my best feature (not to brag) but it was! I looked so much like a scorpion. That's probably why I am the most unique robot constructed so far by our team. That year I attended the Silicon Valley, Los Angeles, and international competitions with my team of 9 students. I didn't make it past eliminations in any of those competitions. It was disappointing, but I was still appreciative of my abilities. Winning isn't everything I told myself, and I just performed to the best of my ability all the way.
