Abstract:
A pushcart in which a user can adjust a balance direction based on his/her own sense even on a slope. The pushcart includes a pair of wheels, driving units, a pair of wheels are supported on a main body unit in a rotatable manner, a grip portion provided on another side of the main body unit, and a support portion that is connected to the main body unit on one side so as to be capable of rotating in a pitch direction and supports assist wheels in a rotatable manner on another side. An angle formed between the main body unit and a direction orthogonal to the ground surface is estimated based on detected angle between the main body and the support portion. An attitude of the main body unit in the pitch direction is controlled based on a target pitch angle corrected using a correction value.
