This sounds like a very appropriate solution since GPS and WiFi are often only intermittently available indoors. Mapping programs are just starting to gather information about the insides of structures to make sense of tghe computed routes. It would be interesting to see the accumulated errors before a waypoint resolve after encountering the next one. I'm guessing the dead reckoning mapped route rescales to align with the known waypoints.
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.
