The video showing our (mostly completed) 1/3rd scale mini version of our FRC bot is here! This bot took more time to build than you would imagine (or at least than what we thought it would). The ball track and drop is made from copper tubing and each was completely re-worked at least four times. The arm effectively has a one way clutch courtesy of a 1/4 drive wrench that we picked up at a flea market. Other than the tubing, wrench, and the mini-bungee cord used to power the arm, everything is made from VEX parts.
I think the end result is well worth the effort and time, it is a GREAT demo unit (especially when the robot isn't here or functional) and is small enough to fit in a car trunk. We hope to join in
FRC 40's mini aim high competition in Atlanta, providing the field can make it.
