Edible bots made of gelatin will crawl into your stomach

Eating a robot might not sound very appealing, but edible machines could be crawling their way down your intestinal tract in the near future. Scientists have created the first part of these digestible bots that could deliver medicine to people in need. The team is working with a hospitality school to see if they could even make them taste nice. The part they have created is just 90mm (3.5in) in length, 20mm (0.8in) wide and 17mm (0.7in) in thickness. This is the first part of an edible robot, which will be biodegradable and have very low levels of toxicity. Experts could train them to walk to humans who are in need of food.
