Tsunami Sumo Robot (2010)

My first Japanese style sumo robot attempt.

4 wheels connected by pulleys with 2 motors.

Robot has industrial sensors for object detection. Very fast response times available. For contrast sensing QRD1114 circuits used.

Robot uses two mabuchi 550 size dc motors for drive system. Motor’s gearbox has only 7:1 reduction ratio.
