Abstract.To approach robustness and optimal performance, biological musculoskeletal systems can adapt their impedance while interacting with their environment. This property has motivated modern robotic designs including variable-impedance actuators and control methods, based on the capability to vary visco-elastic properties actively or passively. Even though variable-impedance actuation and impedance control in robotics is resolved to a great part, a general set of rules by which impedance is adjusted relat…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
