Grant Imahara, eat your heart out! ...Ok, maybe not, but this could potentially give the MythBusting robotics dude some ideas, at least. Someone's come up with a Kondo KHR-2HV robot which uses an iPod Touch as its face, controller input, and overall processing unit.
The guy from Japan who made it and posted the video on YouTube calls it the Robochan app, which can be run on both the iPhone and iPod Touch. The robot itself is named after the app.
Here, Robochan the robot has its movements stored on the iPod Touch. The whole interface to input commands are done via the screen, and you can even teach it new moves to be stored and executed later!
