How Yaw, Pitch and Roll effect the flight of Quadcopter?
5 votes

In a helicopter (which has 2 rotors, one main rotor and one tail rotor) the angle of attack of the main rotor controls the altitude, pitch, and roll. The yaw is controlled by the counter-torque rotor (...

How to model unpredictable noise in Kalman Filter?
3 votes

There will be no control input term. You should take (x, xdot) as your state vector to formulate the Kalman filter properly. The primary sources of noise are the compass and the gyroscope. The ...

Wind force impact on torque mechanical arm
4 votes

If you assume that the wind force you calculated is distributed evenly about the arm (reasonable assumption) then the torque about the shaft is the distance to the center of the arm (20 in) multiplied ...
