Abstract: A system may include a robotic manipulator with a replaceable cover material applied to rigid portions of extension of the manipulator. The system can further include a sensor or other monitoring mechanism that permits a determination of a quality of the cover material to determine whether replacement is warranted, a cover removal mechanism that permits removal of the cover material, and/or a cover application mechanism that permits a replacement for the cover material to be applied to the rigid portion.

Abstract: Embodiments are directed to an inventory system that comprises sensors coupled with an inventory holder and a management module to automatically determine a location of an interaction with an inventory bin of the inventory holder by an inventory item without requiring hand-scanners. The system may determine the location of the interaction with which to associate to a particular bin of the inventory holder based on signal information provided by one or more proximity sensors coupled with the inventory bins of the inventory holder. The system may update information to associate the inventory item with the location of the particular bin in the inventory holder in response to determining the location of the interaction using the signal information.

Abstract: A robotic manipulator can include fingers with rigid members. The fingers may be movable by actuators that are responsive to fluid pressure. A piston may be movable in a chamber to communicate fluid pressure changes from the chamber. The chamber may be fluidly coupled with the actuators so that movement of the piston communicates fluid pressure changes that actuate multiple fingers.
