I recall a time when software documentation was transitioning to CD or online help (online as in on the computer, not yet the Internet). For quite a while to software boxes stayed large as though they were filled with goodies, yet only had a CD or two, quick start guides, warranty information and lots of empty space. I suspected a similar reasoning, although with physical size rather than weight.
The perception that value should be ascribed to weight is deeply rooted in human kind...and possibly has something to do with the weight of gold and the use of that metal as symbol of wealth and a medium of high-value exchange.
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.
