Patent Images
1. A recharge docking system for a mobile robot powered by at least one battery navigating from node to node, comprising:
- means for sensing when the charge of said battery is below a first predetermined level;
means, responsive to said means for sensing, for halting the travel of said robot at its next navigation node when said charge is below said first predetermined level;
means, responsive to said means for sensing, for determining a path from said next node to a base node;
means at said base node for recharging said battery;
means, responsive to said means for recharging, for detecting when said battery is sufficiently recharged; and
means, responsive to said means for detecting, for resuming said travel of said robot from node to node.

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.
