Special Issue Information

Dear Colleagues,

Robotic systems are characterized by their intricate and dynamic nature, making deriving an accurate dynamic model a significant challenge. Traditional analytical methods often struggle to capture the full complexity of these systems due to their nonlinearity and high dimensionality. In contrast, data-driven methods offer a robust alternative by utilizing large datasets to uncover underlying patterns and relationships within the system’s behavior. These approaches leverage advanced algorithms and machine learning techniques to create dynamic models that are both precise and adaptable. By continuously learning from real-time data and adjusting the model accordingly, data-driven methods improve the accuracy of dynamic modeling and enhance the control and performance of robotic systems. This paradigm shift represents a significant advancement in robotics, providing a more flexible and effective way to handle dynamic robotic environments' complexities.

Bio-inspired robots are devices that mimic an animal’s motions and structures in nature. Worm robots are robots that are inspired by the movements of the worm in nature. This robot has different applications such as medicine and rescue plans. However, control of the worm robot is a challenging task due to the high-nonlinearity dynamic model and external noises that are applied to that robot. This research uses an optimal data-driven controller to control the worm robot. First, data are obtained from the nonlinear model of the worm robot. Then, the Koopman theory is used to generate a linear dynamic model of the Worm robot. The dynamic mode decomposition (DMD) method is used to generate the Koopman operator. Finally, a linear quadratic regulator (LQR) control method is applied for the control of the worm robot. The simulation results verify the performance of the proposed control method. Full article
