An automatic truck unloader for unloading/unpacking product, such as boxes or cases, from trailers and containers is disclosed. In one embodiment, a mobile base structure provides a support framework for a drive subassembly, conveyance subassembly, an industrial robot, a distance measurement subassembly, and a control subassembly. Under the operation of the control subassembly, an industrial robot having a suction cup-based gripper arm selectively removes boxes from the trailer and places the boxes on a powered transportation path. The control subassembly coordinates the selective articulated movement of the industrial robot and the activation of the drive subassembly based upon the distance measurement subassembly detecting objects, including boxes, within a detection space, and dimensions of the trailer provided to the control subassembly.

1. A system for unloading/unpacking product from a trailer, the automatic truck unloader comprising: a base structure;a distance measurement subassembly disposed on the base structure, the distance measurement subassembly configured to determine presence of objects within a detection space;a control subassembly mounted to the base structure, the control subassembly being in communication with the distance measurement subassembly, the control subassembly providing instructions for the selective articulated movement of an industrial robot based upon the distance measurement subassembly detecting objects within the detection space; andthe control assembly including a memory accessible to a processor, the memory including processor-executable instructions that, when executed cause the processor to: specify a search operation to identify a product skyline within a product space,specify a search operation to identify an active quadrant within the product space,specify a search operation to identify a protruding product within the active quadrant at the product skyline, andspecify a removal operation to unload the product corresponding to the protruding product. 2. The system as recited in claim 1, wherein the product space is a subspace of the detection space. 3. The system as recited in claim 1, wherein the active quadrant is a subspace of the product space. 4. The system as recited in claim 1, wherein the base structure further comprises a mobile base structure. 5. The system as recited in claim 1, wherein the distance measurement subassembly comprises a three-dimensional measurement system operating on an adaptive depth measurement principle. 6. The system as recited in claim 1, wherein the distance measurement subassembly further comprises a laser range finding apparatus. 7. The system as recited in claim 1, wherein the distance measurement subassembly further comprises a camera. 8. The system as recited in claim 1, wherein the distance measurement subassembly further comprises an ultrasonic measurement apparatus. 9. The system as recited in claim 1, wherein the distance measurement subassembly further comprises an inclinometer. 10. The system as recited in claim 1, wherein the dimensions of the trailer are programmed into the control subassembly. 11. A system for unloading/unpacking product from a trailer, the automatic truck unloader comprising: a base structure;a distance measurement subassembly disposed on the base structure, the distance measurement subassembly configured to determine presence of objects within a detection space;a control subassembly mounted to the base structure, the control subassembly being in communication with the distance measurement subassembly, the control subassembly providing instructions for the selective articulated movement of an industrial robot based upon the distance measurement subassembly detecting objects within the detection space; andthe control assembly including a memory accessible to a processor, the memory including processor-executable instructions that, when executed cause the processor to: specify a search operation to identify a product skyline within a product space,specify a search operation to identify an active quadrant within the product space, andspecify a search operation to identify a protruding product within the active quadrant at the product skyline. 12. The system as recited in claim 11, wherein the product space is a subspace of the detection space. 13. The system as recited in claim 11, wherein the active quadrant is a subspace of the product space. 14. The system as recited in claim 11, wherein the base structure further comprises a mobile base structure. 15. The system as recited in claim 11, wherein the distance measurement subassembly comprises a three-dimensional measurement system operating on an adaptive depth measurement principle. 16. The system as recited in claim 11, wherein the distance measurement subassembly further comprises a laser range finding apparatus. 17. The system as recited in claim 11, wherein the distance measurement subassembly further comprises laser range finding camera. 18. The system as recited in claim 11, wherein the distance measurement subassembly further comprises an ultrasonic measurement apparatus. 19. The system as recited in claim 11, wherein the distance measurement subassembly further comprises an inclinometer. 20. A system for unloading/unpacking product from a trailer, the automatic truck unloader comprising: a base structure;a distance measurement subassembly disposed on the base structure, the distance measurement subassembly configured to determine presence of objects within a detection space;a control subassembly mounted to the base structure, the control subassembly being in communication with the distance measurement subassembly, the control subassembly providing instructions for the selective articulated movement of an industrial robot based upon the distance measurement subassembly detecting objects within the detection space;the control assembly including a memory accessible to a processor, the memory including processor-executable instructions that, when executed cause the processor to: specify a search operation to identify a product skyline within a product space,specify a search operation to identify an active quadrant within the product space,specify a search operation to identify a protruding product within the active quadrant at the product skyline, andspecify a removal operation to unload the product corresponding to the protruding product; andthe product space being a subspace of the detection space and the active quadrant being a subspace of the product space.
