Abstract
A steering mechanism for a track-mounted robot is provided. The steering mechanism comprises guide wheels, which are fixed to yokes that pivot around secondary drive wheels. The pivot action of the yokes allows the guide wheels to maintain full contact with the track and steer as the robot traverses straight and curved portions of the track. Linkage components attach the yokes to a cam follower which follows a cam surface in the track in order to force the proper angle of steering for the guide wheels.
