Project: DeepBlue Juggling #3 - The Hand V1

This video covers my current (working) design for Jugglebot's hand. I explain what the design is and why I'm going to replace it for a (hopefully) better design, which I briefly describe in the second half of the video.
As always, I hope you enjoy it, and feel free to share any thoughts you have on the video!

These video's of yours are hidden gems. Or at least they were hidden gems, since your last video they have been found i guess

This whole project is super interesting

These videos are really cool, thanks. From the view count, you may think that videos with lots of talking and less of flashy demonstrations are not interesting to anyone, but they are really helpful to me. I am currently considering several big projects, and struggle a bit with the scope, which doesn't seem to fit in my head, so listening to you talking about and decomposing your own ambitious project is really helpful. An idea of a concrete design requirements, which appears in several of your videos, while seemingly obvious, does help too :)

Cheers! I'm happy to hear that you've found these videos useful 😊
Best of luck with your projects!!

If you still have the proto lying around, how would crossing the lines have helped? Bottom left would be connected to top right e.g. then the ball would compensate the tilt and try to toss upwards even when angled?

[@harrisonlow]

Hmm, I don't have it in a remotely constructed form anymore unfortunately. Too many moves have happened since then!
I'm not sure if crossing the lines would have helped the issue much. The lines would have had to cross underneath the "cup" part (orange) and I think would have led to the same issue: a tighter line (or premature motor turning) would tilt that side upwards, muddling it all up

@@harrisonlow Hahah I bet :D cheers for the reply. Re-watching from beginning to get grasp of the whole picture!
