ROS, on the other hand, supports various coordinate frames: in the most commonly-used one, X points forward, Y left, and Z up. In ROS terminology, this frame is called "FLU" (forward, left, up), whereas the Unity coordinate frame would be "RUF" (right, up, forward).

WebThe east axis (E) is perpendicular to gravity, perpendicular to the north axis and is in the East direction. The down axis (D) is along the gravity vector.

WebAnswer: A. The Earth rotates to the east (the direction of the sunrise!). This is counter-clockwise when viewed from the north pole down, so the Earth's angular velocity vector \vec {\Omega}_E ΩE points up at the north pole. Once more, we should note the numeric value of the rotation: it's straightforward to see that.
