Haptic communication for mobile robot operations

Abstract

Teleoperations in hazardous environments are often hampered by the lack of available information regarding the state of the remote robotic device. Typically, ideal camera placements are not possible, and an operator is left with the problem of performing complex manoeuvres in the presence of severe blind‐spots. To address this dilemma, we have been investigating the use of a haptic interface, which not only allows an operator to communicate motion commands to a robot, but also allows the robot to communicate to the operator its motion when performing autonomous collision avoidance. This haptic interface provides total operator control, plus vital information that can be used to decide if and how a robot's autonomous operation should be overridden. This paper details our work in this area and presents the results we have obtained from operator/task performance experimentation with this new haptic communication approach.
