        This project is motivated by the Army’s need to increase the mobility performance of teleoperated unmanned ground vehicles. Communication delays make teleoperated driving very challenging especially at high speeds. This project is developing a predictor framework to compensate for the negative impact of communication delays. The proposed approach has the advantage of not requiring a dynamic model of the platform or the human operator. Pilot tests have shown the effectiveness of the approach in improving vehicle mobility with large round-trip delays of 0.9 s.
        Our recent efforts aim to improve mobility of a teleoperated vehicle further by introducing a steering feedforward loop along with the predictors. This talk will first illustrate this extended framework and then focus on the experimental results with human-in-the-loop simulations, where human drivers were asked to teleoperate a simulated vehicle on a virtual track as fast as possible while keeping the vehicle in the center of the track. Results show that, compared to the difference in the performance metrics between the delayed and undelayed teleoperation scenarios, the extended framework can improve the track completion time by 48%, track keeping error by 55%, and steering control effort by 69%, with round-trip delays of 0.9 s.
