GRIP, the Group for Interdisciplinary Psychology at the University of Bamberg have put together a couple tutorials on hacking the Pleo. For those unfamiliar, the Pleo is a small robot shaped like a dinosaur. Their goal was to make it cute and simulate emotion at a higher level than previously attained by consumer robots. Ugobe, the makers of Pleo encourage hacking of the unit and the controlling software. Look at the “developers” area of their site to download all kinds of tools to work on your Pleo.
The two tutorials released by GRIP cover adding wireless communication with a PC and adding a higher resolution camera to the unit. The goal was to make the platform capable of doing facial recognition.
