Nice Control System Demo

I really like the simplicity of this build, want make one whenever I get a chance. A bonafide PID control system using just an ultrasonic sensor and one servo. Very demonstrable, I would call this a robot. This one is Arduino-based, but I bet any processor could do it, maybe even a BS-1 if the program can be squeezed into 256 bytes.

    Ha, I just noticed that his rails are curved, adding stability to the system (the ball will self-stabilize at the lowest spot). Maybe Arduino needs to cheat like that, but we Parallax peeps needn't. :)
