Soft robots modeling and design
Soft robotics is bringing a new view to robot design: future robots will no longer be rigid but made of complex deformable structures, composed of stiff and soft regions, close to the organic materials that we can find in nature. Such deformable robots bring interesting outcomes but their design is complex and very few tools exists to help soft roboticists in this task. The reason is that the behavior of soft robots needs to be modeled and simulated with deformable mechanics that are much more computationally demanding than rigid body simulation. In our team we are developing a theoretical framework for modeling based on finite element modeling and the associated software for real-time simulation of the soft robot modeled.
We are actively developing an open-source toolkit for soft robot simulation withing the SOFA simulation framework.
