Chinese scientists have developed a tiny wormlike robot that can wiggle into tiny pipes to inspect them with an endoscopic camera. The Tsinghua University team said the small robot could navigate pipes in aircraft engines and oil refinery machines, even when they were filled with oil. “Our robot was designed with soft, elastic materials, and thus, with enough force applied, it could be bent to different shapes,” the team wrote in an article published in the peer-reviewed journal Science Robotics on Thursday. Modules of the robot, measuring less than 5cm (2 inches) in length and 1cm in diameter, can be...
