Brief: Based on the analysis of the humans' walking gait, we came up with a new type passive exoskeleton: absorbing the knee negative energy from one side of the leg, and send it to the other side ankle joint to push-off. Therefore we call it "Passive Knee-ankle Joint Cross-coupling Flexible Exoskeleton". This exoskeleton should be able to absorbing both knee negative energy in final stage of swing phase and ankle negative energy in support phase. The best thing is this exoskeleton do not need any ratchet pawl mechanism or active release control device due to the phase match in humans' gait. The only mechanical parts are Bowden Cable.

Division: Almost all of the work is done by me and Zeyu Lu, and we worked together.
