Xenobots are more environmentally friendly and safer for human health as a biological machinery, the study suggests. It may all sound like something weird from a dystopian sci-fi movie, but the researchers say there is no need for get worried about it.

About Xenobots:
One of the most successful creations has two stumpy legs that propel it along on its “chest”. Another has a hole in the middle that researchers turned into a pouch so it could shimmy around with miniature payloads. Xenobots are named after the African clawed frog i.e. Xenopus laevis from which the stem cells arw taken. The xenobots are less than a millimeter (0.04 inches) wide i.e. small enough to travel inside human bodies. They can work together in groups and can walk, swim and survive for weeks without food .
