This paper presents a mechanical system that fundamentally mimics a human musculo-skeletal system aiming for using it in anthropomorphic robots or artificial limbs for disabled persons. At first, it introduces a mechanical module called ANLES (Actuator with Non-Linear Elasticity System). It can be used as a voluntary muscle since it is a linear actuator with non-linear elasticity similar to a voluntary...
The current research effort in the design of lightweight and safe robots is resulting in increased interest for the development of variable stiffness actuators. Antagonistic pneumatic muscle actuators (pMAs) have been proposed for this purpose, due to their inherent nonlinear spring behavior resulting from both air compressibility and their nonlinear force-length relation. This paper addresses the...
