Is this possible to build? what materials/components would I need?

>> No.204352

to be honest i reckon it wouldnt be much of dificulty on the grabbing or individual finger movement with some string down the hollow fingers.
think how your arm and leg muscles work and apply it to the concept?

As a mechatronics engineer, all I can suggest is if you're asking /diy/ then you're in way over your head. Of course that's partially false, as being an engineer I can also answer your technical questions, but do some research and make them more specific.

If this is indeed a robotics project and not some sort of static prob, you'll need to be thinking of control algorithms (or programming each discrete movement on an individual actuator basis)

Also, consider what you'll use as actuators and closed vs open loop. Also whether or not you want to have any sort of sensors e.g. pressure transducers on the gripping surface- no idea what you want to do with this.

You'll need some sort of MCU or logic, and to make up a UART interface for controlling with a PC, (coud even go parallel interface is you keep it open loop) and write your control algorithms in MATLAB, SIMULINK etc. and have them communicate to the drivers for the actuators.

Mechanical aspect would be less challenging- use some wires and torsion springs per finger joint - I don't see you fitting actuating mechanisms in the hand itself if it is to be comparable with normal human proportions.

TL;DR above rant suggests this is pretty technical stuff

For a first project, you could build a syringe robot. Have a look.

Later, you can make something with servoes and microcontrollers.

What function would you like the hand to preform?

that, my fellow friend, is believe it or not, the future of robotics so, just because of your profetical insight into future, you deserve my support

Surely this Anon means *build* a 3D printer

What would you recommend someone use to learn about circuitry and / or electronics?
A book?
A class at a local tech college?
I've been a electronics hobbyist on and off for years but I'm still horrible at it; a lot of it doesn't seem to be well explained.

Polymorph fingers linked to servos. Servos linked to an ssc32 or smaller controller board in turn linked to a pc.

/sci/ has all kinds of good shit in their sticky. I recommend going there.
