Drake
RollPitchYaw< T > Class Template Reference

## Detailed Description

### template<typename T> class drake::math::RollPitchYaw< T >

This class represents the orientation between two arbitrary frames A and D associated with a Space-fixed (extrinsic) X-Y-Z rotation by "roll-pitch-yaw" angles [r, p, y], which is equivalent to a Body-fixed (intrinsic) Z-Y-X rotation by "yaw-pitch-roll" angles [y, p, r].

The rotation matrix R_AD associated with this roll-pitch-yaw [r, p, y] rotation sequence is equal to the matrix multiplication shown below.

⎡cos(y) -sin(y) 0⎤ ⎡ cos(p) 0 sin(p)⎤ ⎡1 0 0 ⎤
R_AD = ⎢sin(y) cos(y) 0⎥ * ⎢ 0 1 0 ⎥ * ⎢0 cos(r) -sin(r)⎥
⎣ 0 0 1⎦ ⎣-sin(p) 0 cos(p)⎦ ⎣0 sin(r) cos(r)⎦
= R_AB * R_BC * R_CD
Note
In this discussion, A is the Space frame and D is the Body frame. One way to visualize this rotation sequence is by introducing intermediate frames B and C (useful constructs to understand this rotation sequence). Initially, the frames are aligned so Di = Ci = Bi = Ai (i = x, y, z) where Dx, Dy, Dz and Ax, Ay, Az are orthogonal unit vectors fixed in frames D and A respectively. Similarly for Bx, By, Bz and Cx, Cy, Cz in frame B, C. Then D is subjected to successive right-handed rotations relative to A.
• 1st rotation R_CD: Frame D rotates relative to frames C, B, A by a roll angle r about Dx = Cx. Note: D and C are no longer aligned.
• 2nd rotation R_BC: Frames D, C (collectively – as if welded together) rotate relative to frame B, A by a pitch angle p about Cy = By. Note: C and B are no longer aligned.
• 3rd rotation R_AB: Frames D, C, B (collectively – as if welded) rotate relative to frame A by a roll angle y about Bz = Az. Note: B and A are no longer aligned. The monogram notation for the rotation matrix relating A to D is R_AD.
Multibody Quantities for monogram notation for dynamics and a discussion on rotation matrices.
Note
This class does not store the frames associated with this rotation sequence.
Template Parameters
 T The scalar type, which must be one of the default scalars.
