Space crawling robot driven by artificial muscles

The invention discloses a space crawling robot driven by artificial muscles. The space crawling robot comprises a body and four sets of leg and foot structures symmetrically distributed on the peripheral side of the body. The leg-foot structure comprises a thigh structure, a shank structure and a foot structure which are sequentially connected through the body, the thigh structure comprises a hip joint assembly, and the hip joint assembly is arranged in the body and the thigh structure; the thigh structure is connected with the shank structure through a rotating shaft, and the coupling position serves as a knee joint of the crawling robot. The foot structure comprises an ankle joint assembly; the hip joint assembly, the knee joint assembly and the ankle joint assembly are driven by artificial muscles arranged in pairs, and the artificial muscles take carbon nanotube fibers as electrodes. The crawling robot can crawl by utilizing the surface structure and material of the spacecraft, has high surface adaptabili
