We're in the middle of a beginner robotics camp. Some are building Disco as best they can without instructions, some are building their own designs, and some are building clawbots since we have the instructions.
My understanding is that VEX designs each game to be able to be played by the clawbot or the season's herobot. Imagine half my campers when they're told that they're building a robot that is illegal as soon as it picks up the claw.
The clawbot being used in the reveal video is violating this very rule, if I'm not mistaken.
Credit to Jonathan Monahan of 663T for pointing this out.
Thanks in advance for clarifying whether the robot in the reveal video violates SG4.
