Worm-like robot could crawl through intestines

At first glance you might mistake this worm-like robot as a child's toy. But the innovative machine is the world's first 3D-printed robot that can move forwards or backwards in a wave-like motion. Its designers hope to miniaturise the robot to make it small enough to swallow, allowing it to crawl along through the intestines to actively visualise the digestive system.

It can climb over obstacles or crawl through unstable terrain like sand and grass, reaching top speeds of 57 centimetres/second – five times faster than similar robots.
