A Study on the Teleoperation of the Unmanned Grounded Vehicle for Improving Telepresence

In this paper, we proposed a teleoperation scheme of unmanned grounded vehicle to improve telepresence. Especially, bilateral control architecture for transmitting realistic steering feeling to the remote driver is investigated. System architecture of the teleoperated remote vehicle is introduced with visual, auditory and kinesthetic haptic channel. Several bilateral control architectures are proposed for transmitting remote steering feeling, and subject tests are done to evaluate the performance. Position-force bilateral control architecture with returning torque compensation algorithm shows best performance.
