Abstract
A recharge docking system for a battery-powered mobile robot which senses when the battery charge is below a predetermined level and halts the travel of the robot at its next navigational node, following which the robot independently plots and negotiates a path from the next node back to a base node at a recharge station, where the batteries are charged.
