A system and method to move a load across a surface. The system has a track on the surface in a first direction, a track cart that moves the load in the first direction and a transfer cart that moves the load in a second direction on a separate cart path. The surface can be corrugated panels having upstanding ribs and the track can have a mounting assembly that mounts the track to the ribs. The track cart slides under the load, lifts the load off the ribs and moves the load in the first direction. The transfer cart is integrated into a gap in the track so the track cart can move over the transfer cart or stop on the transfer cart to move the load in the second direction on ribs defining the cart path. The method uses the components to move the load across the surface.

An automated storage and retrieval system includes a grid-based rail structure and a plurality of remotely operated vehicles arranged to operate on the grid-based rail structure. The automated storage and retrieval system includes a locking device arranged in a zone of the grid-based rail structure where a human and/or a robotic operator is permitted to interact with the remotely operated vehicle or contents of a storage container that the remotely operated vehicle is carrying. The locking device is arranged to lock the remotely operated vehicle against accidental displacement prior to interaction with the human and/or robotic operator, and wherein the locking device being arranged to unlock the remotely operated vehicle once interaction with the human and/or robotic operator is no longer required.
