DOCKING PROCESS FOR RECHARGING AN AUTONOMOUS MOBILE DEVICE

Described herein are technologies pertaining to autonomously docking a mobile robot at a docking station for purposes of recharging batteries of the mobile robot. The mobile robot uses vision-based navigation and a known map of the environment to navigate toward the docking station. Once sufficiently proximate to the docking station, the mobile robot captures infrared images of the docking station, and granularly aligns itself with the docking station based upon the captured infrared images of the docking station. As the robot continues to drive towards the docking station, the robot monitors infrared sensors for infrared beams emitted from the docking station. If the infrared sensors receive the infrared beams, the robot continues to drive forward until the robot successfully docks with the docking station.
