A lifting clamp for an object comprises a plurality of plates stacked and connected together to form seat for a portion of the object, a lifting portion for connecting to a crane or other machine, a pivot leg pivotally connected to the stacked plates for opening the seat, and a lock for selectively locking the pivot leg in a clamped position whereby it grips the object.

An assistive robot system includes a lifting mechanism, a movable arm assembly, a processing device, and a non-transitory, processor-readable storage medium in communication with the processing device. The processing device transmits a command to the lifting mechanism to cause the lifting mechanism to move the movable arm assembly such that a container is gripped within the movable arm assembly, transmits a first one or more signals to the movable arm assembly to cause the movable arm assembly to extend in a system longitudinal direction such that the movable arm assembly grips the container. The movable arm assembly is positioned at a release location and transmits a second one or more signals to the movable arm assembly to cause the movable arm assembly to extend in a system lateral direction such that the container gripped within the movable arm assembly is released from the movable arm assembly at the release location.

In accordance with an example embodiment a clamping device comprising a first clamping device frame element coupled with a portion of a work tool coupled with the utility vehicle, a second clamping device frame element pivotally coupled with the first clamping device frame element, where the second clamping device frame element includes a first section and a second section, where the first section and the second section are positioned at an angle of approximately 90 degrees relative to each other, and a first movement actuator that movably couples the first clamping device frame element and the second clamping device frame element.

An autonomous transport vehicle includes a frame forming a transport payload area of the vehicle. The payload area includes a payload contact support surface that defines a payload support plane that supports the payload. The payload area further includes an articulated underpick end effector that engages and underpicks the payload with respect to the support plane, and extends and retracts with respect to the payload area effecting payload transfer. Payload registration facets are mounted to the frame to engage the payload. The registration facets are disposed to provide, upon engagement with the payload, at least two degrees of registration capturing and securing the payload in a predetermined position in the payload area, and are configured to effect payload engagement with the at least two degrees of registration registering the payload substantially coincident with seating of the payload on the payload support plane of the payload area.

A spreader (24) comprises a main frame carrying container connector arrangements configured to engage with a transport container (10); a rotator enabling rotation of the main frame in relation to a crane bracket about a substantially vertical rotation axis (A2); a rotation motor configured to, responsive to a rotation control signal, operate the rotator to rotate the main frame; a rotation detector configured to detect rotation of the main frame in relation to the crane bracket; and a control system configured to, based on a discrepancy between the rotation control signal and a rotation detected by the rotation detector, generate a rotation alert signal.
