Swiss company senseFly is best known for its fixed-wing industrial drones, such as the eBee and swinglet CAM. Parrot, on the other hand, has made its name with its consumer quadcopters. So, now that Parrot has owned senseFly for a couple of years, what's the result? The new senseFly eXom quadcopter, which uses multiple visual and ultrasonic sensors to avoid obstacles and maintain precise autonomous flight.
