I wanted to check if Team 7700R's intake system is legal or not? how?
The purpose of this Q&A forum is to provide specific rules clarifications, not to attempt a robot inspection based off of a video. There are many aspects of any given design that could result in it being legal or not legal - this is why all robots must go through a full inspection before reaching the playing field. If you have a more specific question that you would like clarification on, please feel free to rephrase and re-submit.
