➀ Researchers at UC San Diego's Bioinspired Robotics Lab have developed 3D-printed robots capable of walking without electronics, powered by compressed gas.
➁ These robots are designed to operate in extreme environments like high radiation zones, disaster areas, and space missions, showcasing continuous operation for three days when connected to a gas supply.
➂ The robots feature a monolithic design printed in one piece using flexible materials, with future plans to integrate gas storage and biodegradable components for enhanced functionality.
