Abstract
This paper proposes a wire-driven supernumerary robotic limb (SRL) that can work closely with a person like an extra arm. The SRL is attached to their body and assists the person in doing activities for daily life. Wire-driven mechanism was adopted for the SRL to secure the safety of the user and make the weight light. The authors designed and built a prototype of the wire-driven SRL and conducted experiments to confirm the feasibility of posture coordination by wires.
