Haptic mobility control for teleoperated rovers

Future missions involving human and robotic systems co-resident on the lunar surface may call for rovers to be teleoperated from the safety of pressurized habitats or vehicles. An approach is presented that emphasizes human-level judgment and intuition in the total control of a rover’s mobility actions. This is facilitated through human-robotic haptics interaction. The concept of a haptics cone control surface is presented, which provides a teleoperator with a means to intuitively determine the velocities he/she is commanding to control rover motion. The teleoperator is also provided with real-time, tasks-relevant haptic augmentation indicating suggestive control actions concerning the desired mobility objective. Utility of the approach for teleoperated control of steep terrain traversal is demonstrated in simulation.
