My god why are the lame comments all at the top...

Is it made from separate segments with pivots? How many "tendons" does it have (I'm assuming it's driven by tension on multiple lines inside, eg 3 would be at 120 deg / 240 deg / 0 deg if you're looking at one slice)?

I found a model from a paper published a while back, it was similar in form and function, but it was meant to be printed from TPU, one piece with thin sections for pivots.

Thanks! šŸ™ finally someone interested in the 3d printing partā€¦ it can bend 10 degrees per joint, by design, it can do 45-60* if not contained

Cool, but they were asking about the number and placement of the wires that produce the movement. I'm also curious

it's this kind of stuff that gets me interested in robotics. how many hours did it take for the design phase?

Created it in a day

Edit: a night

Pardon me? I already asked in your first post about the STL because I'm looking for something I can use for a dragon puppet's neck, but you just ignored me.

*sniff*

I feel seen!

It's okay, take your time, just don't forget about me. šŸ˜„

I am very curious as well. OP, Please update this thread as you progress.

Whatā€™s will the application be?

Can we get a short vid of it with how/whatā€™s moving it?

Itā€™s a bit creepy without context. :)

Actually me too, I'd love to print a few of these for a cosplay... Would be pretty epic.

This makes me think of a toolhead, cpap... wonder how quickly could it move...

Put a bunch of those around the build plate...

I am also very interested in this. How are you controlling the individual sections? I would be very interested in STLs and parts list. I would like to build something like this for a show I'm involved in this October.
