Abstract

This disclosure describes a differential drive cam-over lockout mechanism that enables the drive wheels of a vehicle such as an autonomous mobile robot or automated guided vehicle to be lifted off of the ground and the supporting swivel casters to be forced down to support the vehicle weight. This enables an operator to easily move an inoperable vehicle with human effort. The mechanism is actuated by a differential drive cam-over lockout mechanism that includes a block that can be mounted to the frame of the vehicle and supports a pivoting cam-over bar with a roller. Rotating the cam-over bar causes the roller to ride over the top surface of the pivot arm. The actuating force to rotate the mechanism is provided via a drive ratchet. The mechanism includes a ball detent to ensure that the cam-over bar stays in the stowed or locked position. The mechanism includes bushings and a roller to enable easy operation.
