Abstract

A method of operating a wheel chock for assisting an autonomous machine at a worksite is provided. The method includes receiving a signal indicative of one or more operating parameters of the autonomous machine. The method further includes determining if the one or more operating parameters of the autonomous machine indicate a non-operating state of the autonomous machine. The method further includes establishing a communication between the wheel chock and the autonomous machine, if the autonomous machine is in the non-operating state. The method further includes guiding the wheel chock to be placed adjacent with respect to a set of ground engaging members of the autonomous machine to restrict movement of the autonomous machine at the worksite. The wheel chock is guided by an assisting machine. The method further includes moving the wheel chock away from the autonomous machine when the autonomous machine is in an operating state.

Claims

1. A method of operating a wheel chock for assisting an autonomous machine at a worksite, the method comprising:

receiving a signal indicative of one or more operating parameters of the autonomous machine;

determining if the one or more operating parameters of the autonomous machine indicate a non-operating state of the autonomous machine;

establishing a communication between the wheel chock and the autonomous machine, if the autonomous machine is in the non-operating state;

guiding the wheel chock to be placed adjacent with respect to ground engaging members of the autonomous machine to restrict movement of the autonomous machine at the worksite, wherein the wheel chock is guided by an assisting machine; and

moving the wheel chock away from the autonomous machine when the autonomous machine is in an operating state indicated by the one or more operating parameters of the autonomous machine.
