<ul><li>Researchers at the University of California San Diego have developed 3D-printed robots that can walk without wires, electronics, or batteries.</li><li>The robots are made from a single material, printed in one piece using a 3D printer and are powered by a small cartridge of compressed gas.</li><li>They can function in environments where traditional electronics wouldn't work, such as high radiation areas or space, and can walk on different surfaces and even underwater.</li><li>The team plans to work on storing the compressed gas within the robot and using eco-friendly materials in future iterations.</li></ul>
