WRO 2021 Junior High 108s - Version II - OFDL Taiwan

At 2021/05, we design a simple robot to solve this mission, but this season's junior mission is too complex and too many object are random, so we redesign a new robot and program to solve this mission, the new solution will stable than old one when use at offline competition.
This one is Stable version and not shortest route , some action can be speed up(e.g. waiting cars scan speed, turns, line follow...), In 2021 WRO Taiwan regional online competition we use 98s, the shortest route can reach 8x secs.

How do you detect gray color?

Junior high seems didn't have gray color🤔? To measure grey color I think I will use RGB model.
