Abstract: A mobile robot includes a spin mop, an encoder configured to obtain data from the spin mop and transmit the data to a controller, a sensing module configured to obtain data related to a moving distance or a moving speed, and a controller configured to calculate a moving distance or a rotation angle of the robot based on the encoder data and correct the calculated data using data obtained by the sensing module.
