Abstract: A method for performing tasks on items located in a space using a robot, the items being located proximate fiducial markers, each fiducial marker having a fiducial identification. The method includes receiving an order to perform a task on at least one item and determining the fiducial identification associated with the at least one item. The method also includes obtaining, using the fiducial identification of the at least one item, a set of coordinates representing a position of the fiducial marker with the determined fiducial identification, in a coordinate system defined by the space. The method further includes navigating the robot to the coordinates of the fiducial marker associated with said determined fiducial identification.

Abstract: A system for identifying and tracking performance of operators in a warehouse. The system comprises at least one robot configured to interact with the operators in the warehouse. The at least one robot includes a first transceiver, a proximity detector, and a memory. The first transceiver defines a zone surrounding the robot and the proximity detector is coupled to the first transceiver. The proximity detector is configured to detect entry, into the zone, of an operator and to detect exit of the operator from the zone. The memory contains information identifying said operators who have entered and exited the zone.

Abstract: A robot system includes at least one robot configured to interact with a plurality of operators in a warehouse. The robot has a proximity detector configured to detect the presence of an operator of the plurality of operators when they are within a predetermined distance of the at least one robot. There is a processor configured to retrieve from a memory a set of operator interaction preferences for the operator detected. And, there is a display device configured to allow the at least one robot to interact with the detected operator based on the set of operator interaction preferences of the detected operator.

Abstract: A cover for a roof gutter includes a unitary cover panel received by a plurality of C-clips that are attached to a portion of the roof gutter. The unitary cover panel includes a curved front lip positioned adjacent the roof gutter and an opposite roof-side edge to fit beneath shingles of the roof. The unitary cover panel includes four rows of oblong water siphon slots that are positioned between the roof-side edge and the curved lip. Each water siphon slot includes an opening for water to flow through into the gutter and a depending lip formed to extend below a gutter-facing lower surface of the unitary cover panel wherein the depending lip has a convex upper surface to direct water into the gutter.
