Abstract
A sensor module and a robot cleaner including the sensor module may provide accurate sensing of an obstacle and prevent an erroneous sensing of an obstacle. The robot cleaner may include a body including a cleaning unit to remove foreign substances from a surface of a floor, a cover to cover an upper portion of the body, a sensor module including an obstacle sensor mounted to sense an obstacle, and a sensor window provided at one side of the sensor module. The sensor module may include a light emitting device to emit light through the sensor window, a light receiving reflector on which light reflected from the obstacle is incident, and a light shielding portion interposed between the light emitting device and the light receiving reflector to block the light emitted from the light emitting device from being incident upon the light receiving reflector.
