The Design of Bionic Joints: A Lesson from Synovial Joints

The new form factor is one of the important drivers for future electronic devices. In nature, there are many form factors with evolution process that are elegant and adaptive. In this paper, we explore the characteristics of arthrosis, with the focus on the difference between the arthrosis and machine joints. Then three types of joints are introduced, which are simulated from body arthrosis. With the analyses of the structure and motion track of these joints, the strongpoint of such joints is introduced.
