Below is a short one-minute video showing how a monkey in the U.S. is able to control a robot in Japan—simply by thinking about it. It is impressive technology and it has a host of future applications. In addition to allowing disabled war veterans the possibility of using their thoughts to control prosthetic limbs, it might someday also be used to help the elderly better navigate their environment.
On the slightly more sinister side, the technology might someday allow a soldier located at an army base in Kansas to control a robot in Afghanistan. (By way of analogy just consider that today young air force personnel are controlling drones over the skies in Iraq from the comfort of air conditioned centers in Omaha).
Anyways, I encourage you to check out the video:
