In the past few months, we have covered plenty of cool advanced exoskeleton arms for workers and elderly people. Want to build your own? This project from Kristjan Berce gives you an idea. The idea is to develop an exo-arm with back support to make life easier for the wearer.
You are going to need a force pressure sensor, Arduino Uno, VNH2SP30 motor driver, Car Windshield Wiper Motor, and a few other affordable components to complete this.
