Abstract: A self-propelled object-gathering apparatus includes a chassis, a drive system coupled to the chassis and configured to traverse the apparatus over a surface, and a control system coupled to the chassis. The control system is programmed to detect a bounded operational area, and to guide the apparatus within the bounded operational area. The apparatus also includes a receptacle coupled to the chassis, and a sweep assembly coupled to the chassis and rotatable with respect to the chassis. The sweep assembly is configured to transfer objects from the surface into the receptacle by mechanical action on the objects in response to rotation of the sweep assembly.

Abstract: An object-sorting apparatus includes a housing that extends from a top end to a bottom end, at least one vibration element, and a plurality of stages arranged in a vertical sequence in the housing between the top end and the bottom end. At least one of the stages includes a sorting base that at least partially defines a floor of the at least one stage. The sorting base is coupled to the at least one vibration element, and is configured to receive thereon a mixture of objects having different sizes, including a target size associated with the at least one stage. The stage also includes apertures defined in and extending through the sorting base and into flow communication with a next lower stage. The apertures are sized to receive therethrough, from the mixture, objects having a size smaller than the target size associated with the at least one stage.
