Do you remember when I built openDog version 3 and I designed cycloidal drives – there’s 12 of them in that machine and it’s still going strong. The motors are brushless motors controlled by ODrives and I‘ve got some more projects coming up this year using the new ODrive S1 servo kit which you’ll see in the next few months.

I want to build some much bigger machines though, which will probably move much slower, and I also want to make the designs accessible.

In this video I’m going to design a Cycloidal Drive using a DC brushed motor which already has a gear head on it, and if it goes well I’ll be using it to build some much bigger machines later in the year.
