Emergency Aid drone
Inside the drone is a defibrillator, CPR aids and various medicines. Given that it doesn’t have to fight traffic on the way to the scene, the drone can arrive as quickly as one minute after being dispatched. The idea is that when an emergency call comes in, the drone can head to the scene ahead of the ambulance to help provide immediate assistance.
