ABENICS demonstrates 3-axis rotation using monopole gears, with dual-angle visualization to clearly illustrate the difference in motion. ABENICS (Active Ball Joint Mechanism with Three-DoF Based on Spherical Gear Meshings) is a ball joint system that achieves 3-axis motion (pitch, roll, yaw) using a cross-spherical gear with a monopole gear. A second monopole gear increases robustness, enabling highly accurate, high-torque movement. This demo highlights the difference in motion with dual-angle v
