Researchers in the U.S. have created the first organic robots which measure at less than 1mm long. The living programmable organisms are first simluated using evolutionary algorithms to create random designs using combinations of different stem cell types. Successful xenobot designs are then created in real life using frog stem cells. One suc tiny robot can be programmed to walk in one direction by including a number of heart stem cells which beat nd contract to generate movement.
