Researchers have created the first noninvasive mind-controlled robot arm that exhibits the kind of smooth motion that previously required a brain implant.

If you want to control a robot with your mind — and really, who doesn’t? — you currently have two options.
You can get a brain implant, in which case your control over the robot will be smooth and continuous. Or you can skip the risky, expensive surgery in favor of a device that senses your brainwaves from outside your skull — but your control over the bot will be jerky and not nearly as precise.
