Either way, I don't think my current implementation is particularly bad, especially for how long it took and the fact that it's all COTS. Also, roller claws have definitely been made before, successfully, with exposed motors like this: http://i.imgur.com/PeQIDbJ.jpg

Finally, since I don't plan on actually building this, it's mostly a moot point anyway.

And the motors are still vulnerable to being broken off....
