Scientists have developed organ-like robots based on biological cells

Scientists have developed 'single cell' robots that can work together to perform complex tasks - like organs. The robots are made up of computationally simple parts which, like cells within an organ, work together as a whole to get things done. They can pick up objects near to them, fluidly navigate around obstacles and squeeze through tight gaps. Researchers say the development presents a new way to think about robots, which are traditionally designed for one purpose, comprise many complex parts, and stop working when any part malfunctions.
