SoftCon: Simulation and Control of Soft-Bodied Animals with Biomimetic Actuators

The octopus swims by actuating muscles embedded in the soft tissues.

Abstract

SoftCon is an open source code that implements the work SoftCon: Simulation and Control of Soft-Bodied Animals with Biomimetic Actuators. With our framework, user can generate the swimming animation of under-water animals with deformable body simulator, biomimetic muscle pattern generator, and swimming controller based on deep reinforcement learning. This code is written in C++ and Python, based on Tensorflow and OpenAI Baselines.
