Cockroaches are near-indestructible little creatures. These hardy insects have existed since at least 320 million years ago, outliving dinosaurs. A cockroach can also carry loads of up to 900 times its body weight, shrink to a quarter of its height to fit into small crevices and live for a week without its head.
Inspired by the qualities of this humble bug, a group of researchers from China and the United States have created a prototype of a fast-moving and near-indestructible miniature robot, which could potentially replace sniffer dogs in detecting people trapped in rubble after a major earthquake or similar disastrous event.
Researchers from China’s Tsinghua University and the University of California, Berkeley, published their study on so-called soft robots in the academic journal Science Robotics last week.
