Hello,
Is it legal to make a solid wall in front of your opponents so that they cant see their robots… this would be really funny!!! 
thanks!!!
We love you Karthik!!!
Also…
would it be legal for the other team to walk around the wall!!!
There are no specific rules preventing this type of strategy our design. However you should be aware of the possibility of violating the following rules:
The type of robot/strategy you have described would definitely fall under the jurisdiction of <SG11a>.
If constructing a “solid wall”, you should be careful to avoid becoming an inherent risk of entanglement. This type of design would be highly scrutinized by inspectors.
No, this would be illegal, as stated in the VEX Sack Attack Game Manual
Please be sure to search the manual carefully before posting questions in this forum. This thread has some helpful tips on how to use this forum.
sorry about that… i missed that page… sorry…
Provided that you do not violate the following rule, this would be legal.
