Our robot, Digit, is the first to be sold into workplaces across the globe. As demonstrated in numerous force field experiments, humans combine two strategies to adapt their impedance to external perturbations: 1) if perturbations are unpredictable, subjects increase their impedance through co-contraction; 2) if perturbations are predictable, subjects learn a feed-forward command to counter the known perturbation. Abstract Variable impedance control is essential for ensuring robust and safe physical interaction with the environment.
