D. J. Braun, S. Apte, O. Adiyatov, A. Dahiya and N. Hogan, Compliant actuation for energy efficient impedance modulation, IEEE International Conference on Robotics and Automation, pp. 636-641, 2016.
This paper introduces a minimalistic compliant actuator designed to achieve wide-range impedance modulation with very low energy cost. Unlike previous compliant or biologically inspired designs that required high energy, this actuator demonstrates stiffness augmentation during human–machine collaboration while consuming negligible energy.
Why it matters: Energy-efficient compliant actuation is essential for the next generation of autonomous robots, prosthetics, orthotics, and wearable exoskeletons. By enabling low-cost stiffness modulation, this work provides a foundation for restoring or extending human function and advancing robotic systems that can operate longer and more effectively in real-world environments.
