Abstract

The invention discloses an obstacle-surmounting robot based on a wheel-track-legged chassis, which includes a chassis body, two sets of leg-type rocker systems, two sets of crawler systems, and two sets of wheel-type drive systems. The two sets of wheel-type drive systems are respectively Symmetrically arranged on both sides of the chassis body, the two sets of track systems are respectively arranged in cooperation with the wheel drive system, and the two sets of leg rocker systems are respectively connected with the track systems and wheel drive systems on both sides of the chassis body . The invention has reasonable and reliable structure, small size, superior obstacle-crossing effect, convenient driving, relatively low manufacturing cost, and can move in any direction and rotate on the spot. The cantilever can rotate at any angle around the transmission shaft, which is suitable for complex outdoor and indoor environments.

Description

technical field [0001] The invention relates to an obstacle-surmounting robot based on a wheel-track-leg chassis, belonging to the technical field of off-road robots. Background technique [0002] With the continuous extension of the field of human activities, the working environment of obstacle-crossing robots has gradually penetrated into some unpredictable environments, which requires obstacle-crossing robots to have strong terrain adaptability and efficient and autonomous movement patterns. According to different walking modes, obstacle-crossing robots are divided into various forms such as wheeled, legged, crawler and hybrid. The wheeled structure is simple and the running speed is fast, but there are certain defects in its obstacle-surmounting ability and stability in an unstructured environment. The legged structure has a strong ability to adapt to the terrain, but the control is complicated and it is not easy to meet the requirements of high flexibility. The crawle...
