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.
