摘要:The paper presents the construction and static analysis of a rotation module responsible for conducting flexion-extension motions as part of a medical rehabilitation device of the elbow. The rotation module is actuated by a torsion motor consisting of a pair of agonist-antagonist pneumatic muscles. The study concerning the static behaviour of the rotation module draws upon similarity to the biological model, considering the influence of the neuronal control quantities on the forces developed by the two muscles.
