I have a "copter" of some description, except the whole thing spins. There's the central little body, two wings (at 12:00 and 6:00 say), and two arms with small props (3:00 & 9:00), which thrust horizontally, not vertically. Hovering is...a challenge.
My first thought when I got one of those boards was to build a quadcopter, but then I decided that was too conventional, so I elected to build a tricopter. The three motor setup makes yaw control a challenge, as it is coupled with the other degrees of freedom, but that was to be part of the fun. Not gotten very far along, I'm sad to say.
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.
