Improving the control of prosthetic hands

The quest to develop a prosthetic hand that looks, moves and feels like the real thing.
Modern prosthetic hands look human, but their movements are limited and robotic. Researchers are striving to transform prosthetics by recreating the natural brain-to-hand control signals. At this exhibit you’ll discover the complexity of movements and signals involved in hand control, and how these may be applied in prosthetics.
Current prosthetic hands have the same number of joints as human hands and could theoretically perform complex movements. However, this may not be possible until we understand the complete set of signals that a human hand normally receives. Researchers at Keele and Newcastle Universities are developing ways to convert the user’s desired action into movement of the prosthetic hand, and to generate sensory feedback from the prosthesis to the brain. One way to do this is using machine learning to combine muscle and motion signals from the residual limb. Another way is to feed electrical signals from residual muscles through a computer model to interpret the desired action. Their goal is that one day, prosthetic hands will move and feel like the real thing.

the solution to the nerve feedback is loads of small linear solenoid acutators that is placed in a grid on a pad on the upper part of the arm and then used a variable resistor array on the robotic hand and then use a microcontroller to drive each variable resistor signal to each solenoid on the pad to transelate digital pressure signal into physical sensation in the upper part of the arm.

Each sensor signal could be an input to a RNN, as ground truth one could use a visual tracker for each finger, which converts to desired motor angle. For propioception one could use some presure device or a small electrical shock in any place in the user's body, with practice their natural neural network will learn to associate this with the states of the robotic hand.

A.mendoza-1 yr.ago I need prosthetic hand.

[@gulrukh1386]

Can you help me, which platform you used in making prosthetic hand, your kind and prompt response will highly be appreciated please. thanks best regards Gul Rukh

[@navid9852]

Why not combining other inputs to the EMG signal? for example FMG

[@openbciinc6391]

But did they prototype using OpenBCI??

[@imjusthere-p1g]

This is amazing!

[@arbi018]

I hope one day l can see one thar reacts faster, like an actual hand

[@saltyreboot2279]

cool

[@axax1558]

Please answer me kindly

[@axax1558]

I wait for your answer please

Put all this together and some more of hydraulics with a big generator. And you get a hulk buster..
