This search-and-rescue robot uses static electricity to stick to virtually any surface

The key to any successful search-and-rescue operation is knowing what you’re dealing with, but especially for complex and time-consuming missions, that can be challenging.

One possible solution: tiny flying robots that can canvas an area and return up-to-date information. Current “microbots” tend to run out of energy quickly, but scientists are close to overcoming that limitation. Watch the video above to see how.
