The US government just gave someone a $120-million robotic arm to use for a year

Johnny Matheny is the first person to live with an advanced mind-controlled robotic arm. Last December, researchers from Johns Hopkins Applied Physics Lab delivered the arm to Matheny at his home in Port Richey, Florida. Aside from the occasional demo, this is the first time the Modular Prosthetic Limb (MPL) has spent significant time out of the lab.
