Wallbots: Autonomous Magnetic Robots that Traverse Vertical Surfaces using arduino

This Instructable will teach you how to create magnetic robots that traverse vertical surfaces. These robots can move on any metallic walls, including elevators, whiteboards, refrigerators or metal doors. The robots are outfitted with several light sensors, allowing them to respond to simple user interactions. My implementation supports 3 robot 'personalities', which can be changed by covering the topmost l ...
