System for the Assistance of Performance Motor Skill Learning with a Wearable Robotic Arm

Abstract

We present a wearable haptic assistance robotic system for motor learning. This system comprises two robotic arms that are mounted on a user’s body and are used to transfer one person’s motion to another offline. The system pre-records the arm motion trajectories of an expert via the mounted robotic arms and then plays back these recorded trajectories to share the expert’s body motion with a beginner. The system is an ungrounded system and provides mobility for the user to conduct a variety of motions. In this paper, we focus on the temporal aspect of motor skill and use a mime performance as a case study learning task. We verified the system effectiveness for motor learning using the conducted experiments. The results suggest that the proposed system has benefits for learning sequential skills.
