I don't know anything about Medicine or Technology. What

First, for there to be any advantage we would need some way of articulating the arm that was as fast as normal arm movement and stronger than a normal arm without being too bulky. Currently we don't have anything even close to as good as muscle. Hydraulics are slow and bulky and electronic solutions would be too weak.

So pretty much what we need:
1: Something better than muscles to act as muscles
2: A lightweight, flexible material to make the arm out of
3: A power source to fuel off of this that isn't too cumbersome. I don't think you'll want to carry a backpack with 10 car batteries to run this thing.

On the bright side, research into controlling artificial limbs with brain signals is pretty far along, so that part will be relatively easy to get going.

first initial obstacle i thought of was the difficulty in getting the brain to control it, pretty cool how far along people have come in that field desu

thanks for the answer anon :)

our linear actuators are hot fucking garbage. nothing we have does muscle better than muscle. thats the first step towards synthetic appendages that are truly analogous. efficiency is a big thing too because human beings are crazy energy efficient when it comes to moving around. that efficiency also ties into the power supply dilemma. our batterys are also hot fucking garbage right now.

like >>9070343 said, the man-machine interface technology is the most headway we have made.

imo, we're looking at at least another 50-100 years before you see tech like that.

id say we could produce pretty basic functions with just gearing, its strong and not necessarily all that slow, and could simply be powered by electronics, it just might be abit bulky and complex if you start throwing indivifual finger movements and such into the equation.

They are able to link force feedback sensors to your nerve endings and it literally makes the patient feel the arm as if it's real. As a controls technician this interests me and really gets me thinking about the human nervous system as a collection of analog inputs and outputs. We really are just machines.

Obviously leg is different than arm in terms of functionality/fine motor control but this is always worth a watch.
