Imagine a robotic cell that can function on its own from carrying electric charge, studying the environment around it and changing shape constantly to adapt to it. Sounds like something right out of a fictional, futuristic world where robots are built from cells like humans and can do everything we can, but better. But now, physicists from Cornell University have done just this and given this device microscopic muscles too. The team has successfully created the world's first robot exoskeleton that can rapidly change its shape upon sensing chemical or thermal changes in its environment. The team has even given it electronic, photonic and chemical properties making it a functioning robotic microorganism.
