Funktioniert, aber zu labberig.

Die Sockets der Gelenke benötigen eine Festspannmutter. Wenn ich PLA unter Spannung bringe, wird es mit seiner Plastizität immer lockerer. Schon jetzt schnappen zwar die Kugeln gut ein, aber drehen sich zu locker.

Damit kann man die Figur nicht "formen".

Active Ball Joint Uses Spherical Gear

A common CAD operation is to take a 2D shape and extrude it into a 3D shape. But what happens if you take a gear and replicate it along a sphere and then rotate it and do it again? As you can see in the video below, you wind up with a porcupine-like ball that you can transfer power to at nearly any angle. There's a paper describing this spherical gear as part of an active ball joint mechanism and even if you aren't mechanically inclined, it is something to see.

The spherical gear -- technically a cross spherical gear -- is made from PEEK and doesn't look like it would be that difficult to fabricate. There's also a simpler version known as a monopole gear in the drive system that provides three degrees of freedom.

This looks like just the thing for your next robot arm project. The paper covers the kinematic equations you'd need, but doesn't offer 3D printed models. However, it does mention that the parts were SLA printed, so it is possible to create the system with 3D printed gears.

With the recent trend to merge robot arms with 3D printers, this could be timely. The last time we saw balls used in a robot arm, it wasn't quite for the same reason.

Work in progress of a re-design. I haven't shown this character to but a few people until recently. So it's nice to actually give her the love she is needing! [Akuji, the Artists Daughter]
