A moving robot is provided. The moving robot includes a body, first and second driving wheels configured to move the body, first and second caster wheels installed movably, first and second sensors configured to respectively detect a rotation angle of the first caster wheel and a rotation angle of the second caster wheel with respect to a predetermined direction axis, and a controller configured to control driving of a driving wheel according to the rotation angles. The controller calculates an average rotation angle by using the rotation angles detected by the first and second sensors and controls driving of the driving wheel by using the calculated average rotation angle.
