3D rotations and yaw, pitch, and roll

[@AlJay0032]

This is not the usual definition of yaw, pitch and roll. Normally for airplanes we take a NED coordinate system, which stands for north, east and down. North corresponding to the X-axis, east to the Y-axis and down to the Z-axis. Yaw is rotation around the Z-axis, resulting in the heading, pitch is the rotation around the Y-axis resulting in the nose of the plane being raised and roll is around the X-axis resulting in the left wind being lifted for positive roll. www.chrobotics.com/wp-content/uploads/2012/11/Inertial-Frame.png

hes using a different orientation of axes,

7:27......your welcome :)

[@lifematch]

for Yaw, you wrote cosine theta, not alpha.

check the next lecture

Is this using a column-major order? I thought the rotation axes were actually on rows, not columns.

[@Anvilar1313]

The rows of the matrix are the three independent frame axes expressed in the origin frame, the columns of the matrix are the three independent frame axes of the origin frame expressed in the rotated one.

@@Anvilar1313 Yeah like different frames of reference, right? To transform an object/a single point in a particular direction, you actually need to transform the entire space in the opposite direction.

The Equations are incorrect.

yaw is rotation around z, not x ...

[@JATIN9268]

is it recorded in an IIT?
