<ul><li>Researchers have developed small robots that can work together as a collective that changes shape and even shifts between solid and “fluid-like” states.</li><li>Inspired by tissues in embryos, the robots have motorized gears, magnets, and photodetectors for movement and receiving instructions.</li><li>The current robots are slightly more than 5 centimeters in diameter, but the goal is to reduce their size to 1 or 2 centimeters or even smaller.</li></ul>
