Chinese researchers have developed a diving drone that can switch between flying and swimming.

The device is able to both fly as a standard quadcopter and explore underwater environments like a submersible. Researchers said it can be used for aerial and aquatic surveys, resource exploration, and search and rescue tasks.

A team of scientists from Shanghai Research Institute for Intelligent Autonomous Systems affiliated with Tongji University and another from the Unmanned Systems Research Group at the Chinese University of Hong Kong jointly developed the device, TJ-FlyingFish, which is currently in a functional prototype stage.
