LASER BASED TELEROBOTIC CONTROL FOR ASSISTING PERSONS WITH DISABILITIES PERFORM ACTIVITIES OF DAILY LIVING

摘要

In this paper we demonstrate an innovative use of range information from a laser sensor mounted on the end- effector of a remote robot manipulator to assist persons with disabilities carry out ADL (Activities of Daily Living) tasks in unstructured environments. Laser range data is used to determine goals, identify targets and via points to enable autonomous execution of trajectories. The human operator performs minimal teleoperation and is primarily involved in higher level decision making. We hypothesize that laser based assistance improves task performance in terms of time and accuracy and also reduces the cognitive load on the user executing the task. Tests on ten healthy human subjects in executing a remote manipulation task conform the hypothesis.
