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 […]

It mashes two of my favorite consumer product designs into a cute mutant bot that’s controllable via a web interface. Rather than a huge electronics/robotics exercise, this project is fairly accessible to […]
