Forward kinematics is a fundamental concept in robotics, determining the position and orientation of a robot's end-effector based on joint parameters. It relies on mathematical transformations and the Denavit-Hartenberg convention to model robotic arms and animate characters in 3D graphics. Understanding these principles is crucial for precise control in robotics and lifelike animations in computer graphics.
