Answered: Orientation of Bonus Cube.

At the start of the match, is the orientation of the colored sides of the bonus cube fixed or random? It is shown in all pictures of the field oriented like this:

But could it, sometimes, be like this:

Also, am I correct that the bonus cube and platform can be used for scoring during the autonomous period?

The orientation of the bonus cube will be the same as shown in the manual for all matches. A blue face will always be facing the blue alliance station, a red face will always be facing the red alliance station.

The platform can be used for scoring in both the autonomous period and the programming skills matches. However the bonus cube is not eligible for point in the autonomous period.

During the programming skills challenge, the bonus cube is eligible for points based on the definition of programming skills challenge control.
