  "textContent": "A mechanical leg and a wheeled mobile device, pertaining to the field of smart wheeled mobile devices. The mechanical leg comprises a frame (1), a retractable member (2), wheels (3), an extension/retraction driving member (4), a travel driving member (5), an auxiliary leg (6), and an auxiliary wheel (7). The extension/retraction driving member (4) is located on a side portion of the frame (1). The retractable member (2) is connected to the extension/retraction driving member (4). The wheel (3) is connected to the retractable member (2). The wheel (3) is further connected to the travel driving member (5). A first end of the auxiliary leg (6) is connected to the auxiliary wheel (7). A second end of the auxiliary leg (6) is located on the frame (1). The retractable member (2) extends or retracts under a driving action of the extension/retraction driving member (4) so as to drive the wheel (3) to jump. The wheel (3) moves under a driving action of the travel driving member (5). When the auxiliary wheel (7) contacts the ground, the mechanical leg moves under a rolling action of the wheels (3) and the auxiliary wheel (7). The mechanical leg can move quickly on flat ground, and when encountering an obstacle, the mechanical leg can also jump passed the obstacle, thereby improving the traveling performance of the mechanical leg.",
