the game.
4.2 THE TRACK
The game field, known as the “Track,” is an ovular shaped track with a goal on each end. The
track is similar to a race track and the robots must drive around the field to compete.

an area that can only be occupied by the other alliance for three seconds. Each scoring
zone is also flanked on each side by a Loading Zone. The Loading Zone is where the
Human Player loads racquet balls onto the field for robot retrieval.
