Imagine a robot that can walk without any electronic components, created entirely through a 3D printing process. Researchers at the University of California San Diego have developed an incredible breakthrough in robotics that sounds like something from a science fiction movie. By using a simple desktop 3D printer and basic printing materials, they've created a robot that can move using nothing more than compressed gas.

These innovative robots are remarkably versatile and affordable, costing only about $20 to manufacture. They're designed to function in extreme environments where traditional electronics might fail, such as areas with high radiation, disaster zones, or even in space exploration. The robots can walk on various surfaces, including land and underwater, powered by a small compressed gas cartridge that allows them to move continuously for up to three days.

The most impressive aspect of this technology is its simplicity and flexibility. The research team developed a unique printing technique that allows them to create a six-legged robot using a single material, with integrated artificial muscles and a control system. By using a pneumatic oscillating circuit similar to an old steam engine's mechanism, the robot can coordinate leg movements, allowing it to walk in multiple directions with remarkable precision.
