In this letter, we present the kinematically redundant series elastic dual-motor actuator (SEDMA). It consists of two motors, coupled to a series spring through a planetary differential. The redundant degree of freedom of this system can be exploited to optimize a specific aspect of the actuation ta
Driven by the desire of amputees to reduce their physical shortcomings, prosthetic feet evolved from passive to propulsive bionic feet, actuated by different types of compliant actuators to provide the push-off power and with the advantage of reducing the motor power requirements. The two-latest in-
Modern actuation schematics become increasingly ingenious by deploying springs and locking mechanisms in series and/or parallel. Many of these solutions are, however, tailored for a specific application and a general schematic that allows for drastic energy reduction remains a challenge. We have dev
In recent years, many works have appeared, which present novel mechanical designs, control strategies, or trajectory planning algorithms for improved energy efficiency. The actuator model is an essential part of these works, since the optimization of energy consumption strongly depends of the accura
