Abstract:
A robot cleaner and a control method is provided to prevent wrongly detecting a wall due to steal frame structure affecting the detection of a sensor by sensing wall with a gyro sensor module. A robot cleaner comprises an input unit(110) controlling the robot cleaner by a user, an obstacle distant sensor(120) measuring distance between the cleaner and an object material, a driving part(40) consisting of driving wheels and a drive motor, a mileage detection department(140) detecting mileage information, a foreign substance remove part(60) including a brush rotation motor(62), a foreign material suction part(70) including a suction motor(72) and a controller(100) storing a rotation angle of the robot cleaner in a memory unit(150) after receiving the rotation angle from a gyro sensor module(130), if the robot cleaner drives following the wall.
