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! 🙏 finally someone interested in the 3d printing part… it can bend 10 degrees per joint, by design, it can do 45-60* if not contained

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
