General Information
This competition will involve two robots in a circular ring, with the goal being to push your opponent out of the ring or otherwise disabling them within the time limit. While pushing your opponent out of the ring is the most common way to win a round, disabling your opponent (flipping, lifting, etc.) is strongly encouraged.
Teams for a tournament will consist of 1 or 2 students. A student may only be on one team. Each team will use one robot and robots cannot be shared between teams.

The event will take place on a 4’ diameter smooth plywood ring, painted black, with a 2” wide white border to help the robots determine the edge of the ring. The ring will be raised 1 ½” above the floor (3- 2x4 blocks) to help determine when a robot has “fallen off” (generally determined by the robot touching the ground outside the ring).

1. Robots are to be constructed of 100% LEGO brand parts.
2. No glue, melting or modification of LEGO brand parts is allowed.
3. Only sensors that are supplied with the LEGO Mindstorms/EV3 set can be used. This includes Touch, Light, Color and Ultrasonic. Any combination of sensors can be used.
4. Only one (1) Intelligent brick and up to three (3) servo motors are allowed - NXT or EV3.
5. Robots are to be completely autonomous. The NXT/EV3 robot may not rely on an external computer for computational assistance via infrared or wireless communication. No remote control or bluetooth communication.
6. Robots must fit within a 12" x 12" square. There is no height limit. EXCEPTION: Robot may expand beyond its 12" x 12" size once the bout begins.
7. Robot must not exceed 2.2 lbs.
8. Programming: The first block of the program must be a five second wait block. After the robot waits for 5 seconds it may do whatever you wish. This five second wait block gives all students time to move back away from the board in case an ultra-sonic sensor is used.
Robots will begin side by side, If there is entanglement twice with no scoring then at the judge's discretion a different starting position may be used. Example: starting front to front or facing the same direction.
