Short summary
A new joint mechanism design is presented in this study which has a potential use in robotics, particularly in humanoid robot designs, because of its variable stiffness characteristics, lightweight and remotely-actuated structure. A helical spring inside the mechanism brings compliance which increases the safety. The spring is analyzed with a method proposed in the paper and verified by FEM. The kinematic and the dynamic models are obtained and experimentally validated.
