Paper Abstract

This paper explores the modeling and analysis of the effect of minimum actuation pressure previously observed in literature. This minimum pressure is similar in kind to the minimum amplitude of the signal for muscle actuation seen in mammalian muscles. This minimum actuation, or “threshold” pressure is used a method of mechanically encoding the control of FAM engagement and the actuation efficiency of a group, or ‘bundle’ of muscles with differing threshold pressures is compared with a single muscle of equivalent force and strain. The results of this analysis indicate the efficacy of using this design and control method; it is advantageous in cases where a range of displacements and forces are necessary.
