Autopilot System for Autonomous Aerial Vehicles

Building an autopilot kit is the main concept of this project which can be built and used by anyone in their flying models such as helicopters.

Two dual axis ADXL202 accelerometers are used by the autopilot to read 3D acceleration along with the reading of attitude, position, payload stats, and engine stats. The real-time system OS operates all the readings and control while reading each sensor at some predefined rate. This gives positive results although it is really quite complex system.
From the several sensors on the UAV, the real-time system has to process data which are grouped into four major classes of sensors with multiple input methods. The types of input include analog voltage, RS232, digital, pulse counting, and pulse width modulated. The attitude is the most important method where the real-time system is reading the acceleration rates internally from the gyros and performing rate integration to produce the attitude.

The HAL effect sensor is feeding into the interrupt of the real-time system which counts the pulses and computes the RPM while N1 and N2 are easily sensed from the magnets planted in the engine cooling fan and rotor main gear.
