Popis: Aimed at the current major problems of “slipping, misstep and misplace” in the robot stair climbing process and at reaching the goals of being “flexible, adaptive and stable” in multiple scenarios, a two-wheeled robot with a “4R+2P” pattern that can independently climb different structures of stairs is proposed, and a gait pattern for stair climbing through a four-step cycle of “approaching, lifting, putting and retraction” based on this pattern is proposed. Relevant kinematic and dynamic models are established to study the constraint relation. In the experiment, the robot goes up and down different stairs. The simulation and experimental results showed that the two-wheeled robot with a “4R+2P” configuration fundamentally realized up–down stair climbing, adaptive steering and multiscene functions.
