<p>A variable viscoelastic joint system with a clutch for a human assistance is proposed in this research. The variable viscoelastic joint system comprised antagonized artificial muscles and magneto-rheological fluid brake (MR-brake). This system enabled the human assisting device such as exoskeletons to retain structural softness when compared with the existing devices driven by motor and reduction gear, which could only achieve superficial softness. In this paper, a space saving pulley for antagonized pneumatic muscle is proposed. Generally, required assisting torque of human joints at flexion and extension are different. Therefore, adopting a step pulley is preferable when joints are driven by antagonized pneumatic muscle. However, a step pulley makes a joint system thicker and generates unnecessary torque. The proposed pulley resolve these problem by placing two antagonized wires in the same plane which is vertical to rotation axis of the pulley.</p>
