| The motor shaft, which is co-axial with the axis of the tires, is attached to a metal arm with a roller. The motor body is attached to the wheels. When the robot, inside it's shell, runs into an obsticle, the roller lifts up one side of the robot, and pivots it back slightly. It continues to do this, until it is free. It then proceedes forward, at 6" a second, tracking quite straight, until it finds another object. This little beast roams the halls where I work, sometimes disapperaring for 1/2 a day or more. |
