Inverse kinematics is a computational technique essential in robotics and 3D animation for determining joint angles to achieve a desired end-effector position. It contrasts with forward kinematics and is vital for tasks requiring high precision, such as in robotic assembly lines or surgical procedures. In animation, it allows for realistic character movements by focusing on limb positioning, with software calculating the necessary joint angles.
