Toppling prevention mobile device and toppling prevention method thereof

The invention discloses a toppling prevention mobile device. The toppling prevention mobile device comprises a mobile platform, a supporting frame and a detection device, wherein the supporting frame is located above the mobile platform. The detection device comprises a control module and at least three pressure sensors located between the mobile platform and the supporting frame. The gravity on the supporting frame is transferred to the mobile platform through at least three pressure sensors. The control module is used for reading pressure values of all the pressure sensors and controlling the mobile platform to move according to the pressure values. According to the mobile device, the gravity distribution of the whole device in the moving process can effectively analyzed, and the toppling direction can be detected before a wheel breaks away from the ground. The invention further provides a toppling prevention method.
