This thread might give you a good insight about roll
, pitch
, yaw
in ROS.
Some hints after doing this recently:
Roll is applied first about the X-axis of the previous joint. The frame you're modifying will rotate X radians about the previous X-axis.
Pitch is applied next about the Y-axis of the previous joint. Yaw is applied last about the Z-axis of the previous joint.
Each rotation seems to be capped at pi radians. For example, if you enter a pitch of 3.9 radians, the actual rotation you see will only be pi radians.
