Can I use Ardurover in URC and ERC Rover competitions

Hey, I am researching URC and ERC’s rovers and every rover is using ROS. I taught I can use ardurover. I am an old arducopter user. If you want you can look at URC (University Rover Challenge) and ERC(European Rover Challenge) competition’ documents. I think using ardurover with a companion Jetson or Raspberry Pi for image processing is a really good idea. But I don’t understand why no one ever tries Ardurover in these competitions.
