Imagine a robotic arm that responded to thought, just like a regular arm. What would this be like? These revolutionary new prosthetics may change lives, going from visually appealing plastic sculptures to high-tech almost cyborg-like arms is a big change. If these could become easily available to anyone, this could change the world. Unfortunately, robotic arms that respond to one’s brain are not cheap. But this is one step towards the future of prosthetics.
