On May 10th, 2012, The following updates were made to Appendix F - College Challenge of the VEX Sack Attack Game Manual.
Rule 4, regarding the autonomous mode was amended with Rule 4a, as shown below.
Based on what the Game Design Committee saw at the 2012 VEX Robotics Competition World Championship and feedback from College teams across the world, it was determined that interaction with robots during the autonomous period needed to be severely restricted. This will ensure that teams have ample reason to continue to develop advanced autonomous routines and take advantage of the custom sensing and processing rules in the College Challenge.
On May 14th, 2012, The following updates were made to Section 2 - The Game of the VEX Sack Attack Game Manual.
–
Two clarifications have been made to the definition of Scored. Changes have been bolded for emphasis.
The intent of the first change is to make it clear that a Scoring Object which is overhanging two High Goals or two Troughs is considered Scored in both.
The intent of the second change is to illustrate how the referees will make the determination of Scored when there is an issue of support.
Rule <SG11> has been updated as follows. The new section is bolded for emphasis.
The intent of these additions is to make it clear that if you build a robot that expands to intentionally obstruct the field, your opponents can no longer be penalized for pinning you, and you are not fully protected by <G11>. i.e. You should expect robots to aggressively try and push through you.
–
Rule <SG4> regarding autonomous interaction with the robot has been modified. The new version is as follows:
Based upon what the Game Design Committee saw at the 2012 VEX World Championships, we decided it was necessary to reduce the amount of interacting teams could do with their robots during the autonomous period, however still allow it to be an option. These new rules now mirror the rules for the Programming Skills Challenge, ensure that robots can still be interacted with during the Autonomous Period, however the influence of these interactions will not be overwhelming.
On May 22nd, 2012, the following updates were made to Section 2 - The Game and Section 4 - The Robot of the VEX Sack Attack Game Manual.
–
Rule <SG8> has been updated as follows. The new section is bolded for emphasis.
The intent of this rule is to prevent teams from using Sacks to damage or disrupt opposing robots by dropping them on the robot. However, it was not intended to penalize teams who were trying to score in a Goal that was being blocked by an opposing robot. This new wording makes that clear. If you are trying to Score (i.e. dropping Sacks in a Goal), you will not be penalized if your Sacks land on an opposing robot.
–
Rule <R7c> has been updated as follows. The new section is bolded for emphasis.
The intent of this change is to allow teams more freedom in their hardware choices. You may now use any of the listed screw types, as long as they are no longer than 2".
–
Rule <R7f> has been updated as follows. The new section is bolded for emphasis.
The intent of this rule is to allow teams a variety of choices, while restricting teams to materials that are both safe to cut and to work with. We expect most of our teams to just use polycarbonate as they have in the past, but wanted to make sure alternatives were available for those who did not have access to polycarbonate.
On October 12th, 2012, the following updates were made to Appendix B - Robot Skills Challenge and Appendix C - Programming Skills Challenge of the VEX Sack Attack Game Manual.
Rule has been updated as follows. The new text is bolded for emphasis:
Rule has been updated as follows. The new text is bolded for emphasis:
The intent of this change is to make the starting rules consistent with what is seen in regular matches.
