It's a little slow, but makes up for it with the fact that it has regular NXt motors, Linear Actuators and Pneumatics all in the one design!
From their YouTube page:
This mindstorms robot checkers can play checkers against itself, with a person, another robot, or with a computer.
Language: Matlab (robot vision), C (checkers engine), NXC (inverse kinetic done here, could have done in Matlab)
2 motors for x and y (inverse kinetic)
1 motor for linear actuator (low or raise the piece)
1 motor to switch the pneumatics (grab the piece)
1 motor to provide air pressure to the tank
1 NXTMMX mux to control 2 additional motors.
