About

Dynamics, in the context of robotics and AI, refers to the study of forces, torques, and their relationship to motion in mechanical systems. It extends kinematics by incorporating the physical causes of movement — inertia, gravity, friction, and contact forces — to model how robots and bodies actually behave under real-world conditions. In robotics, dynamic models are used to derive equations of motion for manipulators, legged robots, and aerial vehicles, enabling engineers to design controllers that accurately command forces and torques rather than positions alone. Algorithms such as the recursive Newton-Euler method and tools like Pinocchio make real-time dynamic computation feasible for complex multi-body systems. Dynamics is also central to simulation-based training, where learned policies must transfer to physical hardware, and to biomechanical research studying human and animal movement. Understanding dynamics is essential for achieving stable locomotion, precise manipulation, and safe human-robot interaction, making it a foundational discipline across virtually every area of modern robotics and autonomous systems.
