Dynamic modeling techniques

Definition

Dynamic modeling techniques are methods used to simulate and analyze the behavior of complex systems over time, capturing the interactions between various components and their changes in response to different inputs. These techniques enable researchers and engineers to predict system performance, optimize configurations, and understand the dynamics of robotic systems, particularly in relation to their actuators and movements. By employing these methods, one can better design and refine robotic systems for improved efficiency and effectiveness.
