MOBILE APPARATUS

摘要

The purpose of the present invention is to provide a mobile device, which runs on a bent work method by means of an electromagnet or due to a trolley formed in a triangular structure. In order to achieve this purpose, the mobile device comprises: the trolley; a wheel part vertical to a bottom surface, and installed in the trolley to be able to rotate by contacting with at least one of a first wall surface and a second wall surface connected to each other; a driving part which rotates the wheel part; and a magnetic force part installed in the trolley, consistently maintaining a distance between the trolley and the first wall surface or the second wall surface by generating a magnetic force.
