Here I have these two gearboxes or speed reducers that I made which have the same size and reduction ration of 25:1. I will compare them in several categories, measure their efficiency or torque output, measure their accuracy or backlash, and see how durable they are. I will explain how I designed and assembled both of them, and I will give you some useful tips and tricks for 3D printing them, show you what can go wrong and what can we improve to get them better, things that I have learnt along the way of making several of these. Actually, this is my 4th video talking about these gearboxes, and why is so? Well, these gearboxes are good choice for robotics applications and in future videos I plan to make some robots that will employ this type of gearboxes. 00:00 What are Harmonic and Cycloidal Drives? 02:13 Designing 07:56 3D Printing 09:09 Assembling 15:02 Backlash Comparison 16:25 Torque Comparison 17:46 NEMA23 Torque 19:56 Verdict Visit HowToMechatronics.com for more Tutorials, Tips, Projects and How It Works videos: ► http://howtomechatronics.com Like my page on Facebook: ►   / howtomechatronics
