Re: pic: 775pro Arm Gearbox
Looks sharp! I like the gear-in-tube approach.
One alteration that may help you assemble it more easily, at the expense of more machining work: We used thin pieces of metal to retain the bearings in place in 2009. I'm not sure if they were riveted or we tapped the holes, but you can kinda see it at the top of the robot in this full-res picture. Might be something to consider.

That's a good idea. There are obviously many ways to retain the bearings, and if we actually make this gearbox, I may stick with our usual approach of turning the ends of the shafts down and putting retaining rings on either end.

Re: pic: 775pro Arm Gearbox
Looks great!
I wonder what is the benefit of such gearbox in comparison with some kind of two planetary gearbox configuration with the same rate. Any help? Also, where do you plan to get the first stage gears from?
