Crawling, flying drone could find cracks in bridges

Fujitsu has developed a drone with wheels that can also fly. It can fly up bridge walls to inspect for cracks or other problems and can crawl along the undersides of bridges to look for problems there. A camera is set on the drone at a fixed distance from the infrastructure being evaluated. Only a prototype version has been developed, and the company plans to improve the product. It will most likely be introduced in Japan first.
