Chumby was made for hacking, and so we probably shouldn't be too surprised to see one sprout legs and start its gradual path to world domination. Eric Gregori of EMG Robotics has developed a bipedal walking ChumbyBot by pairing the touchscreen Chumby One with a Freescale MMA7455l controller board.
That board is soon going to be commercially launched as part of the Tower Robot/Sensor board from EMG, working with the company's RobotSee and Robot Vision Toolkit to make for easy vision-based navigation and control. It's also apparently easy to code for, using the same sort of language as BASIC.
