Meet the Droneball: a drone with a 6-axis gyro stabilization system and smart cage that you can fly anywhere safely. It can be maneuvered using a radio control system. In case of a collision, the Droneball stays in the air. The developers are planning to introduce 4K camera, night vision, and other modules for this in the future.
The drone weighs 350g with its cage. It is powered by brushless motors and a 1300mAh battery. It has a top speed of 40 mph.
