Soft robots, designed for surgical applications, pose challenges in modeling and control due to their nonlinear and hysteretic behavior.
Researchers have developed a hysteresis-aware neural network model for accurate prediction of the soft robot's whole-body motion, including its hysteretic behavior.
An on-policy reinforcement learning algorithm is used to train whole-body motion control strategies for the soft robotic system.
The study demonstrates significant MSE reduction and high precision in trajectory tracking for the soft robot, showing promising results for real-world clinical applications.
