AirBurr micro air vehicle can self-right, take off again (video)
 

EPFL's been tweaking its eerily floating AirBurr since 2009, and its latest iteration adds four carbon-fiber legs, hopefully ensuring you'll never have to chase after and recover it after a crash. When the seemingly clunky frame crashes, it's that same intentional design that will ensure gravity rolls the device towards its side, allowing the legs to extend out and let the MAV relaunch itself -- even off gravel. Hit up the source link to see how the design has evolved over the years, but before that, see it crash and burn return right after the break.
