The robotic carton unloader of claim 10, wherein the actuatable element is a claw. 13. The robotic carton unloader of claim 10, further comprising a control and visualization system connected to the conveyor system, the manipulator, and the robotic positioner, wherein the control and visualization system is configured to automatically control the conveyor system, the manipulator, and the robotic positioner to unload the carton pile. 14. The robotic carton unloader of claim 13, further comprising a carton sensor connected to the control and visualization system and configured to detect a distance from the bumper to the carton pile. 15. The robotic carton unloader of claim 13, further comprising a carton sensor connected to the control and visualization system and configured to detect contact of the bumper with the carton pile. 16. The robotic carton unloader of claim 1, wherein the carton pile is a carton pile stacked within a trailer. 17. The robotic carton unloader of claim 16, further comprising: a mobile body; anda drive system attached to the mobile body, the drive system including a plurality of wheels for driving and steering the mobile body, wherein the conveyor system, the manipulator, the robotic positioner, and the frame are coupled to the mobile body. 18. A robotic carton unloader for unloading a carton pile, comprising: a conveyor system;a manipulator movably attached to an end of a robotic positioner and configured to dislodge one or more cartons from the carton pile; anda frame pivotally attached to the robotic carton unloader with at least one pivot, comprising:a pair of frame arms extending outwardly from the pivot;a cross member extending between frame arms at a front end thereof closest to the carton pile;a bumper attached to the cross member and configured to be pivotally repositioned into pressing contact against a front face of cartons in the carton pile directly below the one or more cartons being dislodged from the carton pile by the manipulator, the bumper stabilizing the carton pile directly below the one or more cartons being dislodged with pressure applied by the bumper; anda shelf attached to the frame and configured to catch the one or more cartons dislodged from the carton pile and guide the one or more cartons dislodged from the carton pile onto the conveyor system,wherein when one or more cartons are dislodged, the frame is configured to pivotally reposition the bumper into pressing contact at any height on the carton pile directly below the new topmost one or more cartons slated for removal. 19. The robotic carton unloader of claim 18, wherein the pair of frame arms extend outwardly from the at least one pivot and spread wider therefrom. 20. The robotic carton unloader of claim 18, wherein the frame is configured to pivotally move in an arc towards and away from the floor.
