  "abstract": "A walking mechanism for a quadruped robot includes a support arm and a wheel mechanism. The wheel mechanism includes a first roller connected to a first connecting rod and a second roller connected to a second connecting rod. The first and second connecting rods are controlled to rotate or swing within a vertical plane, causing the wheel mechanism to be in a first state or a second state. In the first state, the first connecting rod is deployed to a first angle relative to a central axis of the support arm, and the second connecting rod is folded upward. In the second state, the first and second connecting rods are deployed to a preset angle. The walking mechanism can both ensure the energy utilization efficiency and travel speed of the quadruped robot on flat terrain, and guarantee the traversability on complex terrain.",
