‘Cockroach robot’ designed to burrow at natural disaster sites

One of nature’s creepiest insects, as it turns out, has inspired researchers to create a very tiny robot that could in theory burrow through natural disaster sites and relay information to rescue workers. A team at the University of California, Berkeley have designed a robot that’s made out of a material known as polyvinylidene fluoride (PVDF) and is the size of a postage stamp. Scientists involved in the project explained that it could have many applications. “For example, if an earthquake happens, it’s very hard for the big machines, or the big dogs, to find life underneath debris, so that’s why we need a small-sized robot that is agi ...
