As drones evolve from military applications to playthings and back again, we're seeing an incredible variety of drone technology from waterproof drones capable of withstanding a splashdown to replicas of Star Wars' Millennium Falcon. Drone-manufacterer DJI has released its newest drone, the Matrice 100. This quadcopter uses an onboard guidance system that has integrated ultrasonic sensors and visual cameras. The onboard guidance system is designed to track the drone's environment from all sides, providing 360-degree awareness of its surroundings. Therefore, the drone should adjust its flight path automatically when faced with an impending obstacle.
