1. In combination, a trailer and an unmanned automated guided vehicle:
- the vehicle comprising a main body having a front portion, a rear portion, opposed side portions, and a top surface, remotely controlled steering means, a pair of front floor engaging wheels disposed along respective sides of the vehicle, a pair of rear floor engaging wheels disposed along respective sides of the vehicle, individual means for bidirectionally driving each of said floor-engaging wheels, a mounting plate attached to said top surface, and hitch means attached to said plate in a centrally disposed location between said side portions and said front and rear pairs of wheels;
the trailer comprising two bar means which comprise means for releasibly coupling to said centrally disposed hitch means;
the centrally disposed hitch means being rotatably connected to said releasible coupling means for movement about a vertical axis extending through said hitch means;
whereby, responsive to the remotely controlled steering means, rotational movement of 360 degrees of the vehicle about said vertical axis without displacement of said trailer is possible as a result of selective directional driving of each of said wheels.

Abstract
A novel trailer towing apparatus for an AGV whereby downwardly applied, vertically oriented towing loads are substantially, directly imposed upon the drive wheels of the AGV, thereby increasing wheel to ground frictional forces and resulting towed load capacity. The towing apparatus is attached to the top of the AGV thereby allowing the AGV to turn through a 360° radius without moving the trailer.
