Read the rules. The very first one answers the question.

An example of unsafe operation is repeatedly throwing balls off the field at audience members, media personnel, judges, referees, etc. An example of an unsafe design is a shooter mechanism that has a large mass that is stopped abruptly at the end of travel and is at risk of breaking off the ROBOT and becoming a projectile.

The answer is basically "Yes, you can, but you'll be penalized and disabled if you do it too often."
