A Geometric Variable-strain Approach for Soft Robots Modeling
The recent growing interest in soft robotics led to significant improvements in the mathematical modeling of such highly deformable structures. An interesting approach is provided by the geometric variable strain methods described in  and , which is based on a strain parameterization of the soft robot. One of the most important features of the model is that it encompasses the geometric theory of rigid robotics as a particular case. Thus, it is able to generalize many of the beneficial properties of this well-established field. The proposed model is well-posed to facilitate the statics and dynamics analysis and low-level control of soft, rigid, or hybrid robotic systems for medical applications.
In this talk, we will describe the theoretical and computational underpinning of the geometric variable-strain approach in detail. Then, its application to concentric tube robots will be shown with a particular emphasis on the implications of the sliding motion .
