Flexy-Hand

That's truly awesome! Did you guys come up with this idea from scratch or is it a remix of another project?

Also, how do the tendons work if someone were to use this as a prosthetic? How would a person bend their fingers using these tendons if they were missing a hand?

I am into flexible filament printing at the moment and this was my idea for 3D printing combination of materials, to give interesting results. This could be printed with a dual extruder machine, with each material being printed with each extruder.

The idea wasn't to offer a direct prosthetic, just to sow the seed of thought into those developers out there who are more specialised in this field. Having said that the hinged figers could be a direct replacement on the Robohand project, using nylon fishing wire as the tendons instead.

Also, how do the tendons work if someone were to use this as a prosthetic? How would a person bend their fingers using these tendons if they were missing a hand?

I'm also curious as to how someone missing a hand could integrate the tendons into their arm so that when they want to close one finger, it will do so. Would it need some sort of motor? I'm not familiar with how traditional prosthetics work. Is there a way to use the electrical impulses from the brain to make the tendons react?
