A method, system, and wheeled base for navigating a robot for docking with a charger docking station (500). The robot (18) receives an initial pose (604) associated with a robot charger docking station (500) and a mating pose (602) associated with the robot charger docking station (500). The robot (18) first navigates from a location to an initial pose (604) using scan matching to a first map. The robot performs a second navigation (742) from the initial pose (604) to the mating pose (602) 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 (500). 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.
