Two-motor quadcore BEAM walker

Robotics Technology

We’ve talked about bicore nervous net BEAM circuits in the pages of MAKE. This two motor walker uses four “neurons” in its brain and is therefore called a quadcore. It’s basically two linked, oscillating signals that create a four-legged walking gate over the two motors. Two photodiodes make the walker light-seeking (or.. um .. shadow avoiding).
