Ryan Walker had just created a 16 R/C servo controller board and needed a platform to test it with. He wired 6 cheap TS-53 servos from Tower Hobbies to the bottom of an empty box. He’s got push buttons on the top for direction control. It uses a PIC18F452 for processing and the board was routed on an LPKF circuit board mill.

There are videos on his site, but try using these cached links first: walking on a table and walking on carpet.
