Practical-use oriented design for wearable robot arm

Abstract

This paper proposes a wearable robot arm designed for practical use. To reduce the weight of the arm, a passive robotics concept is adopted. By replacing actuators with passive actuators the proposed wearable robot arm is able to reduce its weight. Since the coarse movement of the arm is controlled manually by a user’s hand, the user can be safe from unintentional movement of the arm. A prototype which satiates the proposed concept was developed and experiments were performed to verify its usability.
