In response to Anton, it depends on the situation (and what the referee calls). I you're robot makes an obvious attempt to tip the other robot (ramming it and continue pushing when it's off balance or deploying a wedge that upends it, etc.), then it your alliance will be disqualified (which is really bad because the other alliance gets triple their own score!). However, DQ3 clearly states that accidental tipping of robots will be allowed at the discretion of the referees. So if you accidentally bump a robot with a high CG and it tips, you'll probably be fine. Of course, you should be careful with 'accidental

' tipping because you never know what the referees will call. Hope I helped you out.
