“B” could seem like any other quadrocopter around, with vertical circular protections to protect from shocks. The thing is, those innocent protection are also wheels !
As the wheels are taller than the body, it is theoretically possible to lad and the back, and continue driving. The transition from the two modes, driving and flying, can be achieved while moving forward.
The “B” lasts 15mn on a single charge; which isn’t that bad, and packs a HD camera onboard, as well as a microSD slot to save those videos. The Wheels are extremely flexible, making the “B” a kind of super 4×4 that can go anywhere.
