This robot was designed to compete in the "BEAM" Nanomouse robotic competition. As can be seen in the picture the Nanomouse is a scaled down version of the popular Micromouse type events held all over the world.

My particular mouse was the only one to successfully complete the maze, in any amount of time, so it took first place both years entered.

The mouse uses the Motorola 6805kics microcontroller and a National Semiconductor 1 amp dual H-bridge motor driver I.C.. The drive train consists of two modified micro servo's used for very small RC planes. The motors are placed in the standard opposing positions so that the mouse can rotate on its axis. Power is provided by four 110 ma NiCad batteries housed in the pink body portion of the mouse. These can be recharged between runs. Sensing is accomplished by four piano wires that, when touching a wall, come in contact with a copper strip placed along the waist of the mouse. This in turn will activate the microcontroller inputs and the appropriate action will take place.
