@Max....a practical and achievable DIY strategy might be to aim between the two. Use the leaf blower (or two or even 4 of them) and use a controller to control them (and/or control surfaces or vents) such that you can command motion in any direction like the big one, or maybe have an additional leaf blower or a fan for propulsion like a swamp buggy.
Just make sure not to fill it with eels........ :-)
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.
