Mobile robot for supporting smart device

The invention provides a mobile robot for supporting a smart device. The mobile robot comprises a machine body with a mounting position of the smart device and a movement mechanism. The mobile robot is characterized in that the movement mechanism comprises four arc-shaped supporting legs and a rotating power source, wherein the four arc-shaped supporting legs are divided into two groups and are symmetrically distributed at two sides of the machine body; an arc-shaped convex surface of each arc-shaped supporting leg faces downwards to serve as a supporting surface; main bodies of the arc-shaped supporting legs are made of flexible materials; one end, away from the corresponding supporting surface, of each arc-shaped supporting leg, is connected with the machine body by a rotating shaft; rotating surfaces of the two arc-shaped supporting legs at the same side are mutually parallel; the rotating power source is arranged on the machine body and is used for driving the four arc-shaped supporting legs to rotate around the rotating shafts; the four arc-shaped supporting legs jointly rotate to drive the machine body to move. The supporting legs of the mobile robot disclosed by the invention adopt arc-shaped structures, and are made of soft materials, so that the robot has good mobility on the rough road surface or a soft plane, and wear of the smart device and the vibration borne in the movement are effectively reduced.
