ABSTRACT:
A self moving robot cleaner capable of moving to an automatic charging unit to charge its battery when a charging voltage of the battery is decreased to below a predetermined level during a cleaning operation and then again carrying out the cleaning operation. The robot cleaner has a cleaner body, a suction unit provided in the cleaner body for sucking dirt on a floor, a navigation sensor positioned at an upper portion of the cleaner body for sensing a distance to and a direction of an obstacle and for outputting a distance sensing signal and a direction sensing signal, a driving unit positioned at a lower portion of the cleaner body for moving the cleaner body in a moving direction, and a control unit for determining a cleaning area and a moving direction in response to the distance sensing signal and the direction sensing signal from the navigation sensor and outputting a control signal to move the cleaner body and a control signal to drive the suction unit.
