Abstract: A vehicle which goes up and down stairs includes a vehicle body 101, front and rear wheels 102 and 103 provided at the front and rear of the vehicle body 101, respectively, front and rear auxiliary wheels 105 and 107 for lifting up or down the front and rear wheels 102 and 103 by one step of stairs, respectively, a driving unit for driving each wheel, a pivoting unit for pivoting the front and rear auxiliary wheels 105 and 107, sensors 121 to 124 for detecting a riser portion of stairs, and a control unit 120 for controlling the driving unit and the rotating unit in accordance with results of the sensors 121 to 124. Since the vehicle goes up and down stairs by rotation of the auxiliary wheels 105 and 107, a corner portion of the step of stairs is not damaged while the vehicle goes up and down stairs.
