A robot includes a main body and a moving mechanism for moving the main body. The moving mechanism includes a chassis, a pair of wheels, and a supporting unit. The chassis is at a bottom of the main body for assembling the moving mechanism with the main body. The pair of wheels are rotatably and coaxially mounted to the chassis. The supporting unit is pivotally mounted to the chassis. The supporting unit and two wheels are arranged on vertexes of a triangle, and a vertical line passing through the center of gravity of the main body passes through the triangle.
