Abstract: A cargo trailer apparatus is provided. In another aspect, aerodynamic fairings for a cargo trailer are provided. A further aspect employs a cover or fairing, including a curved external surface, attached to a trailer frame below a horizontal plane defined by a top floor surface. Yet another aspect employs a cover or fairing attached to a trailer frame below a floor and behind wheels of the trailer. In another aspect, a pallet or cargo carrier includes a cargo-carrying top surface and roller-engaging channels or guides projecting from a bottom surface. In another aspect, sets of fore-and-aft rollers are mounted to a floor of a wheeled trailer, with the roller sets being laterally spaced apart, and a cargo carrier includes laterally spaced apart structures which move over the rollers while deterring misalignment of the carrier as it is manually slid over the rollers.

Abstract: An autonomous robotic system, and method for automatically monitoring the state of shelves in stores, like retail stores or supermarkets are based on a mobile The mobile robot is capable of autonomously navigating the aisles of a store, with the ability to monitor the condition of product shelves. Specifically, the robotic system solves problems associated with the operation of the shelves, mainly with respect to the detection of incorrect or missing price signs, verification of offer signs, detection of product stock, estimation of product layout, and identification of products misplaced or with errors in the spatial extent assigned to the supplier on a shelf.
