This 3D Rotational DOF (Degrees of Freedom) Mechanism showcases a multi-axis movement system using interconnected gears and universal joints. The upper part rotates smoothly on three axes, driven by a coordinated gear train that converts motor input into complex motion. Often used in robotic arms, flight simulators, and camera gimbals, this mechanism allows precise control over orientation in 3D space. The animation paired with a real-world 3D printed model highlights both design and functionality in action. A great example of mechanical engineering, kinematics, and creative prototyping.
