Noah's+Robotic+Research

= Rehabilitation Institute of Chicago is working on improved robotic arms. = = = ** To restore nerve-activated movement, the scientists started by identifying the nerves that once led to the lost limb. They then redirected these nerves to muscles in the patient's chest. ** ** As a result, when the patient thought about moving his/her arm, the message from his/her brain ended up in his/her chest muscles instead of in his/her hand. The muscles twitched, and a device on the skin picked up the muscles' signal and sent an electrical pulse to the artificial arm, which then moved. **

**One day it might not matter if the hand holding a cup of hot cocoa were real or artificial. The cup would still feel hot.**
