Abstract: This disclosure describes a distributed automated mobile vehicle (“automated mobile vehicle”) system for autonomously delivering orders of items to various delivery locations and/or autonomously returning items to a return location. In some implementations, each user may own or be assigned their own automated mobile vehicle that is associated with the user and an automated mobile vehicle control system maintained by the user. When the user orders an item, the user owned or controlled automated mobile vehicle navigates to a materials handling facility, retrieves the ordered item and delivers it to the user.

Abstract: A shade structure includes a vertical column and a roof having a cover, a framework supporting the cover, and a mount attached for rotational adjustment to a top of the column and supporting the roof on the column. The framework includes a triangularly-shaped main beam arrangement comprising a plurality of beams secured together to form a triangle that lies in a vertical plane and that defines a peak and opposing first corners, with the mount being located between the peak and one of the opposing corners. The framework further includes a pair of transverse beams and a bracing beam secured to the triangular main beam arrangement that define opposing second corners. By this arrangement, an adjustable shade structure is provided that is able to withstand over 40 mph wind loads.
