Getting your colon looked at isn't the most pleasant experience in the world, but this new device from Japanese researchers could make things a little less painful.

It's the world's first self-propelled endoscopy device, which would swim its way through your digestive tract in a matter of hours. Because it's self-propelled, it can be inserted into the digestive tract from either end. Yeah, that means what you think it does. Yikes.

It's piloted remotely via joystick, and it has a built-in camera to show what it sees. It's all pretty crazy, like a real-life version of Inner Space but without people having to be shrunk down to control the ship.
