Abstract: A visual positioning system for mobile devices includes at least one infrared camera, at least one infrared illumination source, and a processor that coordinates operation of the at least one camera and illumination sources. A flood IR infrared illumination source illuminates environmental objects for localization of the mobile device during a first camera exposure window, and a structured IR illumination source illuminate environmental objects for detection and mapping of obstacles during a second camera exposure window. A visual SLAM map is constructed with images obtained from a first camera, with a single map being useable for positioning and navigation across a variety of environmental lighting conditions.

Abstract: A robotic item retrieval and transport apparatus includes at least one item retrieval mechanism that is minimally exposed while stored and/or engaged in loading or unloading of objects relative to a deck (e.g., upper surface) thereof. Actuators and at least major portions of one or more movable implements are arranged below the deck. Loading and/or unloading of objects may include lateral sliding, such as by pulling the object while it is supported by an extrinsic support surface. At least substantial portions of an item retrieval mechanism may remain outside a central target area of a deck, to provide a unobstructed or minimally obstructed deck surface for holding objects. The apparatus may be used with at least one movable pallet element. A pallet element and/or a retrievable item may include one or more features detectable by a sensor.
