Assignee:

Foster-Miller, Inc. - Waltham MA

International Classification:

B62D 13/00

US Classification:

280443, 280445, 280 524

Abstract:

A trailer and hitch system for a mobile robot. The trailer includes a front Ackerman steering linkage, a releasable locking mechanism for releasably positioning the Ackerman steering linkage in a turned position to arrest the trailer, a tow bar extending upwardly from the Ackerman steering linkage and terminating in a lunette ring, and spaced skid members extending downwardly and rearwardly. The mobile robot includes a hitch assembly for the lunette ring. The hitch assembly has a frame including a slot for the lunette ring and a guide portion for guiding the lunette ring into the slot, a latch pivotable with respect to the frame and biased to close the slot, and a decoupling mechanism configured to move the latch to release the lunette ring from the slot. A robot arm is maneuverable to engage the decoupling mechanism.
