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.

Moving robot and method of calculating moving distance of the same

The present disclosure relates to a mobile robot, including: a mop module having a pair of spin mops, which rotate clockwise or counter-clockwise, and a mop motor configured to provide a driving force to the pair of spin mops; a sweep module disposed forward of and spaced apart from the mop module, and having a collecting part, which forms a collecting space to store foreign materials, a sweeping part configured to introduce foreign materials into the collecting space while rotating, and a sweeping motor configured to provide a driving force to the sweeping part; a body, on which the mop module and the sweep module are disposed; and a first floor sensor disposed forward of the sweep module, and configured to sense reflectance of light reflected from a floor.
