Final reduction is about 400 to 1. Application is controlling the shoulder joint on our arm.

When I first saw this, I was all “Holy cow!”

And then I was all “How’d they do that?”

Just curious–what vintage are those motors? 2004? 2005? 2005.5?

nice…

They are the 2005 kit motors.

It screams at 12 volts. It is acceptable at 6 volts, but may not have enough umph to do the job. Right now, we are planning on limiting it to ~9 volts in programming, with the option to bypass that if the need arises.

Very Nicely Done

I helped on this project, and since this post I built a wicked nice guard for the motors out of sand-balsted 0.050" aluminum sheet, hopefully Andy will post an updated picture of it with everything mounted.
