Question: If someone gets a nechanic arn/leg then how do people get it so accurate?

Great question, and it’s really tough. The nerves in your body are amazingly complicated, sending messages to and from your brain about senses like touch, pain to controlling movement. So trying to wire a mechanical arm up to react to those signals is really tough, but there are loads of researchers and doctors working to make the system better and better.
