Abstract

A recharge station for a mobile robot and method for navigating to a recharge station. Two signal emitters on the recharge station emit uniquely identifiable signals in two separate ranges. A mobile robot is configured to look for the signals with two signal receivers, a left receiver looking for the signals of the left emitter and a right receiver looking for the signals of the right receiver. Upon sensing the left emitter signals with the left receiver and the right emitter signals with the right receiver, the mobile robot is aligned with the recharge station. The mobile robot is configured to then drive forward until charging contacts on the mobile robot make contact with charging contacts on the recharge station.
