Beautiful, I'm quite curious about the next video where you hook up the bluetooth and use it!! Great design, nice to also see the small fans inside the housing. Nice details of your work.

Very nice work. Looking forward to seeing how it works out. Super tricky project, so well done for tackling it.

Nice idea with the “mismatched” planetary gears. Now, you could add a potentiometer to register the absolute angle. 👍👍👍

You should do a final episode! It could help with maybe students who want to do robotics in the future (like me). Videos like that with the simplified robot would be much appreciated by not only me but a lot of people. Nonetheless, we thank you for keeping us updated and helping us with all the videos.

@03:35 You can simply create a press fit cover for the inside which will in turn hold all the nuts in place. Falling nuts into a PG system is no fun and will not be an issue if the cover is placed.

@JohnLauerGplus

5 жыл бұрын

Good idea. It would add some height to the system, but probably could make the cover be 0.6mm height, so wouldn't add much. Those planetary gears do rub along the top where those nuts are. The top sun gear does push itself up towards the roof of the gearbox. So do the planetary gears, so the smoother the roof, the better. A cover could help that be even smoother than having those nuts exposed. As I've seen the grease squeezes up into the nut holes over time. Although, I do think it makes sense to have some gunk repositories where over time the shreds of plastic can bunch up and get pushed into depressed areas to help give longevity.

What is the output torque with the planetary gearbox included?

It's a really cool project, but the shaky camera drives me crazy!!

You don't sand gears, you "lap in" gears. Apply a fine lapping compound to all the gears and run them until they get quiet. The lapping compound is basically grease and sanding media and the teeth of the gears will rapidly wear away the spots that interfere on the gear teeth. This has been the acceptable practice since modern gears were invented.

@JohnLauerGplus

Interesting. I am working on a BLDC version of the actuator now. I'm printing the new compound planetary gear in nylon and indeed I am breaking in the gears by running them raw against each other and it is smoothing them out. However, what lapping compound would you use for plastic to make this process faster/better? I can't find any when you search google for "3d printed gear lapping compound".

@JohnLauerGplus

4 жыл бұрын

So far the arm is like $95. No, doing this in metal would be very hard given the intricate details. Maybe 3D metal printing could work, but the weakest point isn't the plastic, rather it's the stepper motors. So the material doesn't matter as much as you think. Going stronger would require more gear ratios. Harmonic drive would be amazing if we could all figure out how to print a harmonic drive.

How many DOF or axis is this arm?

Why not use servo motors and forget the gears?

Yes, I agree. That base should be raised by about 0.5mm or even 1mm to sink the M3 screws further. The downside is the sun gear height is exactly the shaft gear height to get full contact, so you'd end up with the sun gear 0.5 or 1mm higher, but that probably is an ok tradeoff.
