Abstract: A method, system, and wheeled base for navigating a robot for docking with a charger docking station. The robot receives an initial pose associated with a robot charger docking station and a mating pose associated with the robot charger docking station. The robot first navigates from a location to an initial pose using scan matching to a first map. The robot performs a second navigation from the initial pose to the mating pose using scan matching to a second map, thereby causing an electrical charging port of the robot to mate with an electrical charging assembly of the robot charger docking station. Localization during charger docking may use a higher resolution map than when navigating to the docking station. Localizing against the robot charger docking station may be performed on a higher resolution map of the docking station alone.

Abstract: A method for queuing robots destined for one or more target locations in an environment, includes determining if a plurality of robots destined for the one or more target locations have entered a predefined target zone proximate the one or more target locations. The method also includes assigning each of the robots to either its target location or one of a plurality of queue locations based on an assigned priority. The plurality of queue locations are grouped into one or more queue groups.

Abstract: A method for generating a navigation map of an environment in which a plurality of robots will navigate, includes obtaining an image of the environment defined by a plurality of pixels, each having a cost value. The environment includes an image of a fixed object having a set of pixels corresponding to its location and having a first defined cost value. The method includes obtaining a planned path image for the robots, which include a first set of pixels corresponding to the location of each robot in the environment and a second set of pixels adjacent to the first set of pixels and extending along a planned path of travel toward a destination. The first set of pixels of each robot having the first defined cost value and the second set of pixels having a second defined cost value. The second defined cost value is less than the first defined cost value.
