[G27]

Deliberate or damaging contact with an opponent Robot on or inside its Frame Perimeter is not allowed.
Violation: Technical-Foul and potential Yellow Card

Deliberate contact as in purposefully defending or hitting a robot ON its frame perimeter with or without bumpers sounds like a Technical-Foul.
