Cycloidal drives are fascinating pieces of hardware, and we’ve seen them showing up in part due to their suitability for 3D printing. The open source robot arm makers [Haddington Dynamics] are among ...

This video showcases a simplified 3D printed cycloidal drive, known for its high torque density with an 8:1 gear ratio. The orange eccentric shaft represents the input, while the blue load plate shows ...

What’s better? Harmonic or cycloidal drive? We aren’t sure, but we know who to ask. [How To Mechatronics] 3D printed both kinds of gearboxes and ran them through several tests. You can see the video ...
