Engineering is just one trade-off after another. We could try making it from transparent aluminum and painting the inside white for privacy, but that would shield the radios and sensors, and putting the antennae and the sensors on the outside would compromise it's in-atmosphere performance.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
