The utility model relates to a novel carbon fiber foot plate which comprises an upper foot plate, a lower foot plate, an artificial limb connector and a connecting device. The front ends of the upper foot plate and the lower foot plate are fixedly connected through a connecting device; the artificial limb connector is fixedly connected to the top of the upper foot plate through a fastener; the rectangular pyramid is used for being connected with an external artificial limb structure, the ring seat is used for protecting the carbon fiber mold pressing head, the carbon fiber mold pressing head is used for limiting and fixing, and the threaded insert is used for reinforcing connection. The rectangular pyramid, the ring seat, the carbon fiber mold pressing head and the threaded insert are fixedly connected through a carbon fiber mold pressing process. The utility model has the advantages that the full-foot long sole design and the tow connecting device are adopted, so that better rolling performance can be provided in the walking process, and better walking experience is provided for a user; the weight of the sole product is further reduced through the design of the molded artificial limb connector with the nonmetal carbon fiber as the main body, so that the burden of the stump of the user is reduced, and the stump of the user is better protected.

The invention relates to the technical field of robots, and discloses a complex terrain inspection robot path planning and gait optimization method, which realizes cross-scale parallel perception of a macroscopic grid and a microscopic landing point for the first time through multi-scale terrain perception and uncertainty quantification, fundamentally solves the fundamental contradiction of macroscopic passability and microscopic inaccessibility, and improves the accuracy of the route planning and gait optimization of the complex terrain inspection robot. By constructing a multi-constraint collaborative planning and foot-ground interaction time-varying model, the microcosmic landing point accessibility and the terrain evolution law are fused into path-gait joint optimization, and the full-cycle conflict between walking dynamic stability and operation static stability is radically solved. Aiming at the problem of coupling resonance of contact operation of the foot-type robot, a cross-domain coupling dynamic model is established, millisecond-level real-time solution of an edge end is realized by adopting model order reduction and a lightweight network, resonance is actively inhibited, the operation precision is ensured to reach + / -1N / 0.5 mm, a full-link uncertainty nonlinear conduction and risk grading closed-loop correction mechanism is introduced, and the operation precision is ensured to reach + / -1N / 0.5 mm. And self-learning and self-healing of the system are realized.

The application discloses a hip-knee joint integrated structure for a power prosthesis, characterized in that the hip-knee joint integrated structure comprises a prosthesis hip joint (1), a power transmission system (2) and a prosthesis knee joint (3); the prosthesis hip joint (1) is fixedly connected with the prosthesis knee joint (3), and the power transmission system (2) is fixedly connected with the prosthesis hip joint (1); the power transmission system (2) simultaneously transmits power to the prosthesis hip joint (1) and the prosthesis knee joint (3) in two directions, drives the prosthesis hip joint (1) to complete a hip flexion action, and drives the prosthesis knee joint (3) to complete a knee flexion action. The hip-knee joint integrated structure can improve the joint motion coordination ability and improve the gait of an amputee, and a set of power system can be used to improve the energy utilization rate. The hip-knee joint integrated structure can also simulate the pulling effect of leg joint muscles on the joint, and meanwhile, the jerk feeling that may exist in the periodic motion process of rigid transmission is avoided.
