What comes to my mind with the question of software for both Toyota and self-driving cars is both architecture/design and understanding safety/failure modes. Although the details are vague, it sounds like there were both architecture/design issues and safety issues.
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.
