Shock routine in autonomous mode

Is it legal for the autonomous routine of a team to collide with our own robot to block our routine?
In the last tournament we lost in the finals that way. My team was undefeated throughout the tournament. But when we played the final in the autonomous period his robot collided with our robot in the same point blocking it so that it did not make any point. Previously we realized that they recorded our routine but we did not imagine that they did it for that reason. They said that their autonomy was failing, but in the three matches that we played their robot always tried to block ours.

Blocking a robot’s route in Autonomous is perfectly legal.

And what about G10?

Blocking another team’s auton wouldn’t be considered an infraction under G10. This is perfectly legal during normal gameplay. Infractions refer to things that aren’t legal in driver control, such as entering the opponent’s 10 point zone. So if they had done that during auton, and it affected the winnner of the auton bonus, you would automatically get the bonus.

What about G10? What would the infraction be? The closest thing you might have is pinning and that is only illegal during driver control according to SG4.
