<div dir="ltr">So my team tried to get in touch with Motus after
looking at their public info and they pushed us off until after
the new year, but they aren't responding at all now. However
their drive still looks interesting. Harmonic (strain wave)
drives and cycloidal drives seem to be what Motus is competing
against.
<div><br>
</div>
<div>So I've been exploring the ins and outs of these kinds of
"gearboxes" as I continue my forlorn quest for high reduction,
back driveable, hollow shaft (pass through wiring) and
affordable joint drives. I thought I'd just share a few
links:</div>

<div>The clearest explanation of harmonic drives I found:</div>

tuned to hobbysts</div>

<div>I'd not heard of them before but that drive looks
interesting. My team has reached out to Motus and they
want to meet with us in February. They say they are a bit
busy at the moment.</div>
