Researchers make a more anthropomorphic hand design on robots to give them the better motion and control, like a human hand. via spectrum
“The conventional approach to designing anthropomorphic robotic hands often involves mechanizing biological parts with hinges, linkages, and gimbals in order to simplify the seemingly complicated human counterparts. This approach is helpful for understanding and approximating the kinematics of the human hand in general, but inevitably introduces undesirable discrepancies between the human and robotic hands since most of those salient biomechanical features of the human hand are discarded in the mechanizing process. The inherent mismatch between mechanisms of these robotic hands and biomechanics of human hands essentially prevents us from using natural hand motion to directly control them. Thus none of the existing anthropomorphic robotic hands can achieve the human-level dexterity yet.”
