PROBLEM TO BE SOLVED: To provide an autonomous coverage robot and a related navigation system.SOLUTION: There is provided an autonomous robot system including a navigation beacon equipped with a beacon emitter which transmits a first emission, and a base station. The base station includes a base which determines a docking direction and a field emitter which radiates a second emission aligned with the docking direction. The autonomous robot includes a nondirectional receiver which detects the first and second emissions, a directional receiver which detects the second emission, a drive system which moves the robot, and a controller which controls the drive system. When the nondirectional receiver detects the first emission, the robot does not pass the first emission while when the nondirectional receiver and the directional receiver detect the second emission, the controller determines the position and direction of the base so that the robot is docked to the base station.
