Summary

This article deals with the benefits of using elastic soft Robots. For now, the approaches to create them are made by inspiration from nature but with their high elasticity it's really hard to control them. So it's necessary to know how to modelize their movement and that's what the article explain with the Finite Element Method ( FEM ) in order to model the deformations that are the cause of a mechanical coupling.

So, in first the author insist on the difficulty to anticipate the movement because of the infinite number of degrees of freedom, and also on the several advances made on this subject by other scientists. But to control a soft robot he explains that we need a real-time computation and than to algorithms adapted to GPU, the computation time can be reduced.

After that he explains the principle of the FEM. Before everything he needed to know the constitutive law of the soft material by making stress-strain response under tension experiments
