Drones can be used for more than just fun, or military purposes. Yesterday, we came across a very hardy and rugged Hiro Action Sports drone that we theorized can be used for rescue scenarios. Now, we get wind of a drone that has actually been specifically designed for such use cases. Flyability's GimBall might not look like any drone you've seen so far, enclosed inside a geodesic cage. But that odd form is precisely what was needed to make the UAV suitable for even the most dangerous environments.
