AR Drone Developer Guide Notes

• Each pair of opposite rotors is turning the same way. One pair is turning clockwise and the other is turning anti-clockwise. 
• Varying left and right rotor speeds the opposite way yields roll.
• Varying front and rear rotor speeds the opposite way yields pitch. 
• Varying each rotor pair speed the opposite way yields yaw. 
• Drone can be set in light and low wind drag config. 
• Tags can be added to the external hull to allow several drones to easily detect each others via their cameras. 
• If a propeller encounters any obstacle, the drone will detect if any propeller is blocked and stop all engines immediately. 
• The drone has many sensors are are used for stabilization and assisted tilting control, VS control, hovering, and trimming. 
• All manoeuvres are completely assisted. 
• Alt limit, yaw limit, vs limit, tilt limit can all be tuned. 
• The front camera is a CMOS sensor with a 90 degrees angle lens. 
• Connect to drone via Wifi network.
• Drone contains a 3 axis magnetometer sensor and pressure sensor. It also measures ultrasound performance. 
• Drone uses a standard USB-A connector. 
• Drone library contains high level API's to access the drone.
