Haptically Augmented Teleoperation
This article presents various experiments conducted at the Stanford Robotics Group to enhance teleoperation thru the use of movement constraints. Several types of constraints have been studied : Safety constraints, limiting the movements of the slave robot into safe areas and robot and guidance constraints, helping the operator to move according to a predefined geometrical path (along a line, on a plane). Those constraints have been implemented using force feedback on the master device and potential fields are used to compute the amplitude of the force feedback according to the constraints.
