When an operator in a moving vehicle is performing a manual control task, the accelerations to which the operator is subjected can result in unintentional control inputs. This biodynamic feedthrough (BDFT) depends on the properties of the control device and of the control limb. Humans can adjust the dynamics properties of their limbs, effectively changing the limb admittance. Previous studies of BDFT...
This study investigates the use of force-stiffness feedback, i.e., a combination of force offset and extra spring load, in UAV tele-operation with transmission time delay. The goal was to further increase the level of safety of tele-operation with a reduction in operator workload with respect to force feedback, i.e., using force offset alone. A theoretical analysis is given of using force-stiffness...
