Modeling of the energy savings of variable recruitment McKibben muscle bundles

BIOINSPIRATION, BIOMIMETICS, AND BIOREPLICATION 2015, Vol. 9429.

By: M. Meller*, J. Chipka*, M. Bryant n & E. Garcia*

author keywords: McKibben muscle; energetics; efficiency; variable recruitment; fluid power; hydraulic control systems
TL;DR: Simulations of several different loading scenarios are discussed that reveal the benefits of such an actuation scheme, and greatly lessens the pressure drops by effectively changing the actuator area, leading to much higher efficiencies over a broader operation envelope.
