Answered: vex round up

when you start the match does your entire robot have to be on the coloured mat or can just your wheels or treads me touching it.:smiley:

Let’s take a look at the applicable rule in the VEX Round Up Game Manual

The only applicable restriction to your question is for the robot to be touching one of the starting tiles. Hence, the robot only needs to touch the tile, not be entirely contained by it. So just having a wheel or tread touching it would be legal.
