This is my personal robot Marvin, he is still a project in progress (a robot is never finished). He is build after the Leafproject which is a opensource AI robot project, try doing a google seach on leafproject and robot. He is quite advanced, with speech recognition and Speech using MS speech engine, vision by opencv and roborealm, online newsreader, collision avoidance wtih ultrasound and brain running an AI LISP program. All hardware is custommade by me. The body is mostly aluminium and expanded PVC. I have a blog on www.klitgaard-design.dk where you will find more information.
