Where must the robot be positioned before the match begins?

The correct position for the robot before the match begins is with the bumpers over the starting line. This positioning is critical as it ensures that the robot is properly aligned for the start of the match, adhering to the official rules that dictate where robots must be placed at the beginning of gameplay.

Starting with the bumpers over the starting line allows the robot to be ready to engage immediately once the match starts. This positioning not only facilitates a fair start but also helps teams strategize their initial movements and plays effectively based on their robot's capabilities and design.

The other options do not fulfill this requirement; being off the playing field or inside the team's pit would mean the robot is not ready for competition. Furthermore, positioning the robot on the opponent's side violates the rules regarding starting placement, which is designed to maintain an orderly and fair competition.
