120:1 Two-Stage Cycloidal Gearbox - Machined

grabcad

The 2-Stage Cycloidal Gearbox is specifically designed for FIRST Robotics applications. To optimize performance, it has been reworked to be machined instead of 3D printed. Research has shown that this design change can significantly improve the gearbox's overall efficiency.
