Abstract: A mechanical leg comprises a frame, a retractable member, a wheel, an extension and retraction driving member, a travel driving member, an auxiliary leg, and an auxiliary wheel. The extension and retraction driving member is located on a side of the frame. The retractable member is connected to the extension and retraction driving member. The wheel is connected to the retractable member. The wheel is further connected to the travel driving member. A first end of the auxiliary leg is connected to the auxiliary wheel, and a second end of the auxiliary leg is located on the frame. The retractable member extends under the driving of the extension and retraction driving member to drive the wheel to jump. The wheel is driven by the travel driving member to move. When the auxiliary wheel contacts the ground, the mechanical leg moves with the rolling of the wheel and the auxiliary wheel.

Abstract: A method for determining a plurality of layers of bounding boxes of an object includes determining a polyhedron capable of accommodating the object therein as a first-layer bounding box. The method also includes selecting one vertex from a plurality of vertices of the first-layer bounding box as a target vertex, and determining, by processing circuitry of a computing device, a support plane of the object. The support plane has a normal vector that has a specific direction corresponding to the target vertex and that is closest to the target vertex, the support plane being a plane passing through a point on a surface of the object such that the object is completely located on one side of the support plane. The method further includes cutting the first-layer bounding box based on at least the support plane to form a smaller bounding box, as a second-layer bounding box.
