The bionic foot body comprises bionic arches, extension springs, a compression spring, a viscoelastic material layer and rubber non-slip mats. Part of impact borne by the bionic foot can be consumed by the viscoelastic material layer, and the rest of the impact is absorbed by the elastic deformation of the bionic arches, the extension springs and the compression spring. Due to the fact that the rubber non-slip mats are adopted, the non-slip performance of the bionic foot can be improved. The bionic ankle comprises a first ankle joint connecting piece, a first ankle joint platform, a second ankle joint connecting piece and a second ankle joint platform. The bionic ankle can do inward turnover and outward turnover movement through the rotation of the first ankle joint platform around a third pin shaft, and can do back bending and toe bending movement through the rotation of the second ankle joint platform around a fourth pin shaft. By means of the bionic foot, the harmful effect caused by the impact can be effectively reduced, meanwhile, the walking mode of human beings can be imitated, and the gait of the robot can be more natural.
