It seems the parallel processing ability of the prop makes it a top candidate for autopilot brains. This project was entered in the Parallax Design Contest and won second place!! The designer opted for a fuzzy-logic algorithm over a kalman filter for the IMU.The OughtToPilot employs a non-linear fuzzy-logic algorithm to blend two different types of inertial sensors (accelerometers and gyros) in a computationally efficient manner. This model free blending and estimation method was chosen over Kalman filtering to reduce the design-side system modeling effort and the real-time computational burden. All computations are conducted upon integer based pseudo float numbers with most values corresponding to a fractional number with three digits after the decimal point, multiplied by a thousand.The source code and material list is available from the link above.
Jason did a great job documenting his project in his code. For those not familiar with the parallax SPIN code though is is just text, I suggest you download their editor which displays SPIN code more clearly and has a special electronics component font.
coudl be possible to extract the Anti Crash Tecnology sensor to use it onboard in another plane? looks like a cheap version of FMA Copilot, but they dont sell it alone
