1. An automated guided vehicle (AGV), comprising:
- a support structure;
a drive mechanism being attached to the support structure, the drive mechanism moves the AGV along the ground; and
a stabilization system being attached to the support structure and having a leveling assembly that includes an extension member, wherein the extension member extends away from the AGV and engages the ground or an assembly installed in the ground to help level the AGV by supporting at least a portion of the weight of the AGV when the drive mechanism is not moving the AGV along the ground;
wherein the leveling assembly includes a lead screw having a threaded rod with a generally vertical longitudinal axis, and the threaded rod rotates to extend the extension member away from the AGV and supports at least a portion of the weight of the AGV.

Abstract
An automated guided vehicle is equipped with a stabilization system for precisely locating, leveling, or otherwise positioning the AGV and its payload with respect to a work piece. The stabilization system includes one or more extension members that extend away from the AGV to engage the ground or a locating assembly installed in the ground. Each extension member may be part of a locating assembly or a leveling assembly. The locating assembly extension member may extend at least partially into an opening of another locating assembly to align the two locating assemblies. The locating assembly may also be configured to provide a leveling function.

12. A stabilization system for an automated guided vehicle (AGV), comprising:
-
an upper locating assembly being attached to the AGV; a lower locating assembly being installed in the ground at a known location; and an extension member being part of either the upper or lower locating assembly and extending axially towards the other of the upper or lower locating assembly, wherein the extension member causes the upper and lower locating assemblies to be in a locked engagement when the AGV is at the known location and not moving along the ground; wherein the extension member includes one or more finger(s), that extend radially from the extension member and mate with corresponding features of the other of the locating assemblies so that the upper and lower locating assemblies can be in a locked engagement at the known location. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. A method of using an automated guided vehicle (AGV), comprising the steps of:
-
(a) moving the AGV to a predetermined location along the ground; (b) extending an extension member from the AGV toward the ground; (c) causing the extension member to engage the ground or a locating assembly installed in the ground; and (d) stabilizing the AGV at the predetermined location; wherein the method further comprises providing AGV stabilization information from one or more stabilization sensor(s) to an electronic control unit (ECU), and controlling the extension member using the AGV stabilization information. - View Dependent Claims (22, 23, 24, 25)

26. An automated guided vehicle (AGV), comprising:
-
a support structure; a drive mechanism being attached to the support structure, the drive mechanism moves the AGV along the ground; a stabilization system being attached to the support structure and having an extension member, wherein the extension member extends away from the AGV and engages the ground or an assembly installed in the ground to help stabilize the AGV when the drive mechanism is not moving the AGV along the ground; an electronic control unit (ECU); and one or more stabilization sensor(s) being mounted to the AGV and electronically coupled to the ECU, wherein the ECU receives AGV stabilization information from the stabilization sensor(s) and uses the AGV stabilization information to help control the extension member, wherein the one or more stabilization sensor(s) includes a clinometer that provides the ECU with stabilization information regarding an angle of one or more axes of the AGV with respect to the earth. - View Dependent Claims (27, 28, 29, 30)
