Section 3.2.6: ROBOT-ROBOT Interaction
The rule change to G27 attempts to discourage ROBOT to ROBOT damage, while still allowing defensive play. On the FIELD, we want to encourage FRC Teams to work with their ALLIANCE partners to demonstrate their technical prowess and game play skills. While pushing and bumping are reasonable game play efforts, anything that resembles intentionally damaging behavior is not. Additionally, the change to G27 enables Referees to issue penalties for causing opponent ROBOT damage, even if not strategic or intentional.

The blue box in G28 is being modified to reflect the fact that it is possible for contact between two extended elements to result in a penalty, if the conditions of G27 are otherwise met.

G27

Strategies aimed at and/or game play resulting in the damage, destruction or inhibition of opponent ROBOTS via actions such as high-speed or repeated, aggressive ramming, attachment,damage, tipping, or entanglement of ROBOTS are not allowed.

Violation: FOUL. If strategic, TECHNICAL FOUL. and Potential YELLOW CARD

For example, use of a wedge-like MECHANISM to flip ROBOTS would be considered a violation of G27.

MECHANISMS outside the FRAME PERIMETER are particularly susceptible to causing such damage and drawing this penalty and/or penalties associated with violations of G28. Teams are encouraged to be cautious in their use of such appendages when engaging in ROBOT to ROBOT MATCH play.

G28 (Blue Box only)

High speed accidental collisions may occur during the MATCH and are expected. Generally, ROBOTS extend elements outside of the FRAME PERIMETER at their own risk; no penalties will be assigned for contact between two such extended elements.

Not sure how I feel about this yet...seems like too much room for judgement calls...
