[Scott team 48]

I see no penalties here only if the redabot is completely preventing the bluabot from escaping, however, if there is plenty of room for bluabot to drive around them, I view this as a penalty. As far as pinning is concerned, its only pinning if they are making contact with bluabot, while bluabot is being pushed into another object, i.e. the wall. My understanding is that in this scenario there is a pocket of space between redabot and the wall, bluabot has room to move around behind them, but due to the size of redabot, they can't physically get out of the home zone.

No penalty in my opinion assuming the above paragraph is met, but seeing the match would make that call more clear if it were to ever happen.
