The patent's assignee for patent number 11999206 is Robotic Research OpCo LLC (C larksburg, Maryland, United States). News editors obtained the following quote from the background information suppli ed by the inventors: "An 18-wheeler or tractor-trailer truck includes a semi-tra iler (also referred to herein as "trailer") releasably coupled to a tractor (als o referred to herein as "truck" or "vehicle"). At distribution centers, marine t erminals, rail heads, etc., the trailer is often disconnected from the truck, fo r example, for cargo loading, cargo unloading, storage, or changing between truc ks. In such locations, rather than the truck used for road hauling, the trailer can be moved about by a specialized local tractor (also referred to herein as "h ostler," "hostler truck," "yard truck," "yard dog," "terminal tractor," "shuttle truck," or "shunt truck"). However, trailers have a pneumatic parking brake (al so referred to "spring brake" or "emergency brake") that mechanically engage whe n the tractor's pressurized pneumatic lines are disconnected (e.g., via gladhand couplers on the trailer). Thus, to allow movement of the trailer by the hostler , the trailer parking brake has to be disengaged by pressurizing the pneumatic l ines. This requires manually connecting pneumatic lines between hostler and the trailer, as automatic connection tends to be difficult or subject to failure. No t only does manual connection of pneumatic lines require additional time and sub ject a user to potential risk, but it also limits the adoption of automation (e. g., automating operation of the hostler to move trailers) at such locations. Emb odiments of the disclosed subject matter may address one or more of the above-no ted problems and disadvantages, among other things."
