Abstract:Abstract. This paper describes the design and control of a suspension based on electroactive polymers for controlling the landing dynamics of a jumping robot. Tunable suspension elements can electrically change their stiffness up to a factor of 10 in less than 0.01 seconds. We discuss design parameters and performance relevant to bio-inspired systems and demonstrate the ability to operate in positive (actuator), neutral (spring-like), or negative (damping or braking) workloops. When applied to a singlelegged r… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research 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 students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
