Abstract
An automated handling system for moving objects from one location to another location is provided with a self-mobile system having a grabber subsystem for grasping objects, including assemblies for movement in four directions, along X, Y and Z axes and through an angle θ. The system also has a translating carriage assembly for moving the grabber subsystem and power supply and drive systems. A sensing device, such as an imager, is provided to determine the geometric position of the objects and to move the grabber subsystem accordingly. Another embodiment of the system is provided as an accessory to a prime mover. It includes an alignment articulation system, a gross advance system, a tine storage system, a loading head system, and pot grabbers. This automated handling system can be used to move plant containers in nurseries from the ground to a trailer bed and/or from a trailer bed to the ground in a variety of container configurations.
