Snake-like soft robots are highly adaptable to different kinds of environments with flexibility. A well-studied and feasible locomotion pattern for snake robots is the crawling locomotion with the anisotropic friction properties of their contact surface. However, due to their frequently changing shapes, the design of the gaits for snake robots is often intuitive and normally derived from either trial and error and simplification of physical structures, making it hard to find an automatically control policy. We propose a modeling pipeline based on a framework for the simulation of soft robots, SoMo, which defines the snake body as a concatenation of links connected with joints, allowing users to adjust parameters such as physical properties of joints and frictional properties. This research also lays the foundation of future development of the control system.
