This invention belongs to the field of wheelchair technology and relates to a wheel-legged intelligent wheelchair robot, comprising: a frame body, a height-adjustable and posture-adjustable seat system mounted on the frame body, and four wheel-legged composite mobility mechanisms symmetrically distributed on both sides of the frame body. This invention, through the design of the seat system, can adjust the seat posture in real time during stair climbing, ensuring the occupant maintains a comfortable, nearly horizontal sitting posture. Furthermore, through the design of the four wheel-legged composite mobility mechanisms, in flat ground mode, each drive wheel is grounded, enabling high-speed and efficient wheeled movement. In obstacle-crossing or stair-climbing mode, the robotic arms work in coordination, and the drive wheels act as "feet" to step on steps, achieving stable climbing similar to a quadruped robot through multi-arm coordinated gait. This invention combines the efficiency of wheeled systems with the strong obstacle-crossing capabilities of legged systems, enabling autonomous and stable traversal of complex terrains such as stairs and curbs, greatly improving the freedom of movement for people with mobility impairments.

This invention relates to the field of wheelchair technology and provides a stair-climbing chair with auxiliary support legs. The chair includes a frame with two track frames on the back, each with a track. Two front wheels are mounted at the front of the frame. Two reciprocating rear wheel legs are mounted on each side of the frame, each with a rear wheel. A support leg is rotatably mounted on the outer side of each track frame, with a support wheel at its lower end. The two support legs have a supporting posture and a retracted posture, and can synchronously rotate to switch between these postures.
