Abstract
A method and system for docking a robot with a charger docking station, including receiving an initial pose and receiving a mating pose associated with the robot charger docking station, performing a first navigation from a location to the initial pose, and performing a second navigation of the robot from the initial pose to the mating pose. The second navigation may proceed substantially along an arc path from the initial pose to the mating pose, thereby, upon arriving at the mating pose, an electrical charging port of the robot mates with an electrical charging assembly. The arc path may be associated with a section of a unique circle having a radius and a center equidistant from the initial pose and the mating pose. Controlling for error may include a proportional control and/or weighted control or switching between the controls to maintain an error below a threshold.
