I am an avionics student and I mostly focus on unmanned aerial vehicles (UAVs). Recently I got an idea of interconnected drones. These drones could acomplish a task which can only be done by one big heavy drone. This increases the efficiency and unfortunately the costs also. I need to make at least 10 small drones in order to put this idea into reality.
As I see it a bunch of small drones working collaboratively could make dangerous jobs done by humans (i.e. where big heights included) safer and quicker to finish.
