Hi Angelo – do you mean a 3 legged robot? No, I don’t think I have? Most of the robots I’ve made have wheels. But a few years ago one of the students in the lab made a 6 legged robot – a hexapod called MARV – and that worked perfectly. It was able to walk, and if it bumped into things it would back away then turn and go around the obstacle. Here’s a web page with some pictures of MARV walking http://www.ias.uwe.ac.uk/Robots/marv.htm
