A mobile robot includes a mode of operation to recover from a localization error. The mobile robot detects a change in state in a local region proximate the mobile robot. The location of the mobile robot is identified based at least in part on the detected change in state. In one implementation, the mobile robot interfaces with a system controller of a building to initiate a change in state in a local region of a building.

Apparatus, system, and method for mobile robot relocalization

A method for a robot to autonomously interact with elevator controls comprising: while physically traversing a route to a target location within an environment, determining that the route includes navigating to a particular floor that is different than a current floor of the robot; navigating to a set of one or more elevators along the route; identifying a location of an elevator call button corresponding to the set of one or more elevators; navigating to the location of the elevator call button and pressing the elevator call button, wherein pressing the elevator call button comprises: rotating the robot in place until a vertical structure faces the elevator call button; extending or retracting the vertical structure until a button pushing element is aligned with the elevator call button; moving towards the elevator call button and causing the button pushing element to press the elevator call button.

A passivating layer is deposited on the facet of a light emitting device comprising a thin layer of a reactive material. The thickness of the passivating layer is sufficiently thick to react with an optimum amount of contaminants on the facet but is sufficiently thin so as to be consumed in the gettering process and render the layer electrically nonconductive, if initially conductive in nature. The reactive material may be selected from the group consisting of Al,Si,Ta,V,Sb,Mn,Cr and Ti. Al has been found to be particularly good as a passivating layer with a preferred thickness for the layer being in the range of about 20.ANG. to 75.ANG., depending upon whether the layer is for purposes of surface passivation or interface passivation.
