Robot capable of synchronously climbing stairs

Abstract

The invention relates to a robot capable of synchronously climbing stairs. The robot comprises a tray component, a first walking component, a second walking component and a rotation driving device, wherein the tray component comprises a first support member, a second support member and a third support member, of which the mutual distance and height can be adjusted according to stair steps, the first walking component and the second walking component are respectively connected to the lower ends of the first and third support members and are the same in structure, each walking component comprises an axle, a left wheel member and a right wheel member which are located at the two ends of the axle, the two wheel members are symmetric and identical in structure, shape curves of each wheel rim consist of end-to-end-connected Archimedean spirals and arcs, then, the distance from the wheel rims to the axes of the axles is changed along with rotation, and the rotation driving device is mounted at the lower end of the second support member, is in transmission connection with the first walking component and the second walking component respectively and drives the first walking component and the second walking component. The robot can bear a heavy load, keep horizontal, stably and automatically climb the stairs and walk on flat ground.

Description

technical field [0001] The invention relates to a dynamic balance robot, in particular to a synchronous stair-climbing robot, which belongs to the technical field of robots. Background technique [0002] At present, the main implementations of stair-climbing robot climbing steps are legged, crawler and wheeled. Among them, the legged stair-climbing robot generally achieves the purpose of climbing stairs through bionics. Ensure the balance of the body. In addition, people or animals can determine their own step distance and step height parameters by judging the steps of the stairs through their senses. However, it is difficult for ordinary legged robots to achieve stable control of the center of gravity; crawler crawlers The building robot directly uses the crawler transmission to achieve the purpose of crawling, but its disadvantages are that it is bulky and inflexible in movement, which limits its use; the wheeled floor climbing robot directly uses the rotation of the whee...

Among them, the legged stair-climbing robot generally achieves the purpose of climbing stairs through bionics. Ensure the balance of the body. In addition, people or animals can determine their own step distance and step height parameters by judging the steps of the stairs through their senses. However, it is difficult for ordinary legged robots to achieve stable control of the center of gravity; crawler crawlers The building robot directly uses the crawler transmission to achieve the purpose of crawling, but its disadvantages are that it is bulky and inflexible in movement, which limits its use; the wheeled floor climbing robot directly uses the rotation of the wheels to achieve the purpose of crawling, flexible movement and simple control, but due to The wheels are round and it is difficult to rotate synchronously when climbing steps and to achieve a stable center of gravity like movement on a flat surface
