How much? I have bought stuff from Schunk for work, so I doubt the price
would surprise me much. I'm not buying a new harmonic drive
I've seen both harmonic gearboxes and that Galaxie put into robotic
applications. The Galaxie is super strong, high torque, and has very good
stiffness from input to output, which is critical in some (medical) robotic
applications. The max output speed is probably lower than the harmonic
drive, b
Perhaps these are over designed for a lot of projects?

Suppose I wanted to build a duplicate of this with slightly longer arms.

I have one of these

It looks a lot stronger.

That looks like an excedrin headache to try and print.
IMO, this is designed to get around any patents that might still exist
Really nice. Looks similar to a harmonic drive but more complicated. It
would be awesome to see what are the advantages of these over harmonic
drives.
