How Does The Parrot AR Drone Work? If you have learn my Quadricopter page, you may have a primary understanding of how all quad rotor RC helicopters work, so I won't get into that. What I need to briefly clarify right here is how the auto pilot system on the Parrot AR Drone functioned and the limitations. Please Visit Parrot AR Drone Quadricopter There are essentially 3 sensory input's that the autopilot within the Parrot AR Drone detects and corrects for. First off is a 3 axis gyro/accelerometer. This enables the AR Drone's auto pilot to detect any pitch, roll, or yaw movement and proper as needed to keep the heli stabilized. This is very similar to the digital flybareless stabilization programs all us RC heli persons are familiar with. Next up is an ultrasonic sensor system pointing down on the ground to accurately establish altitude position. This ultrasonic system could be very accurate up to about 3 meters (10 toes) or so. After that it does not work that properly but you may turn that portion of the autopilot off permitting you to fly as excessive as you wish. With the Parrot AR Drone in that altitude range above the ground, the auto pilot will hold a set altitude very well. The third autopilot sensory enter is from a small digital camera that is pointed down at the ground. This digital camera will detect any X/Y axis floor movement and along with the gyro/accelerometers on board is able to hold a deadly accurate position over a hard and fast point. As the altitude increase, in fact the much less accurate this becomes, however up to 20 ft or so it appears to be not too bad.
