^^^^^^^^^^^^^^^^^^^

When considering rotations about an axis, consider yourself looking down the
positive axis of rotation from the positive towards the origin. Positive
rotations are then counterclockwise, and negative rotations clockwise.

Figure 1: Coordinate Axes Rotations

A rotation example: consider looking down the positive Z axis towards the origin. This
would be like standing in the middle of the field, looking down. A positive
rotation about Z (i.e. a rotation parallel to the X-Y plane) is then counterclockwise.
This comes from the `right hand rule <https://en.wikipedia.org/wiki/Right-hand_rule>`__ of classic geometry.
A rotation example: consider looking down the positive Z axis towards the origin.
This would be like standing in the middle of the field
looking down at the intersection of the tiles in the very center of the field.
A positive rotation about the Z axis is then counterclockwise.
Therefore a robot spinning counterclockwise on the field is making a positive rotation about the Z axis.
This rotation convention comes from the `right hand rule <https://en.wikipedia.org/wiki/Right-hand_rule>`__ of classic geometry.
