This paper documents the mechanical system of the Electric Cable Differential leg, and its incorporation into a monopod hopping robot named Thumper and a bipedal robot named MABEL. The ECD Leg is designed with physical springs and other passive dynamics to match a mathematically simple, bio-inspired mass-spring model, which can exhibit robust and economic walking and running gaits. With this de...
