The picture above is from MakerFaire 2009.
I also took it to RoboGames 2009 where it won "Best
of Show" in the Open category. As at MakerFaire, it was very popular with children -- but very few adults actually sat
down and played a game.

The big black box is the robot arm controller. The small silver box is the PC running the software. The box in the upper
left controls the hand.
