This year’s game is played on a 12′ by 12′ foam tile field. There are two alliances (red and blue) with two robots each. Each alliance places their robots on the appropriately colored square at the beginning of the match. A 15 second autonomous period is then followed by a 1 min and 45 seconds driver-controlled or “tele-op” period.
The field is initially set up as above. The picture is color coded to show the various scoring zones and obstacles. The alliances start in the Hanging and Middle zones. The smaller colored balls are called Buckyballs. Buckyballs can be scored in the Middle zone, the Goal zone, and the hexagonal tubes in the Goal zone known as Stashes. The larger colored balls are called Large Balls (read beach ball). Like the Buckyballs, they can be scored in the Middle zone, the Goal zone, and because of their size, only on top of the Stashes.
There are two obstacles. The bump is located between the Hanging zone and the Middle zone. It’s 2″ high and trapezoidal. The “barrier” is located between the Middle zone and the Goal zone. The barrier is in fact only thin PVC pipe suspended 12″ above the field.
To begin the match a robot must fit within an 18″x18″x18″ cube, although it can expand during autonomous to be as large as the team wants. In addition, the rigid height can not be greater than 12″ to fit under the barrier. The drivetrain must also have at least 2″ of clearance to go over the bump. The top edges of the Stashes are at 24″. To reach the Hanging bar, a robot must be able to extend or hook something at the height of 40″.

A perfect robot would be lightweight, fast, able to hang with a Large ball, go over the bump, under the barrier, and score Buckyballs and Large balls in the Stashes.
