BattleSumo 2.0
BattleSumo is a game where two robots push each other off the ring and avoid falling out or avoid being pushed out by the opponent robot. The first robot that touches the ground loses the game.
Octa Field
1. The playing field is 8' octagon.
2. Outer ring's width is 2" and colored white.
3. The rest of the inner area is black.
4. The starting box is 2.5 feet square marked by light thin lines.
Robot Specifications
1. Must be capable of autonomous and remote-controlled mode.
2. Maximum size of robot is 2.5' x 2.5' x 2.5' (length, width, and height) at stationary (off) position.
3. Maximum weight of robot is 10 kilograms.
General Rules
1. Failure to show at the playing area 2 minutes after scheduled time will cause the team to forfeit the game.
2. Judges decision is final.
3. The referee may recall teams for a tie-breaker round if needed.
4. Robot must not damage the other robot. Harmful robots will be disqualified. The objective is to push the opponent, not to damage.
5. Robots must not emit smoke, fire, or fluids, throw or shoot projectiles, jam, electrocute, electromagnetically interfere, employ nets, strings, or rope.
6. No person will be allowed 4 feet near and around the ring when the game starts except referees.
7. Inspection of robot weight and size will occur before the game and will be left on the table to avoid modifications after inspections.
Game Rules
1. Each match is composed of 3 rounds
2. Each round has a maximum of 2 minutes. Time and game stops when a winner is called for a round.
3. Round 1 and 2 is played in autonomous (Auto) mode or pre-programmed.
4. Round 3 is played in remote-controlled (RC) mode.
5. Robots always start inside the box in every round.
6. A robot or any of its parts that touches the ground first loses the round.
7. A robot not inside the box during the start loses the round.
8. Robots cannot be touched during game play. A robot touched by any team member loses the round.
9. Any means of interference on the robots by a team will cause that team's robot to lose the round.
10. For round 1, robots face each other.
11. There is a 1-minute break after round 1. Game can resume early if both teams are ready.
12. For round 2, the winner of the previous round positions their robot first, and then the opponent will follow.
13. If there is a tie in round 1, or if robots are deadlocked, both robots face outwards and opposite each other to start another round. This is considered round 2.
14. There is 3-minute break after round 2 in which teams has to convert their autonomous robots to remote-controlled. Game can resume early if both teams are ready.
15. For round 3, robots are remote-controlled facing in any direction but will still have to start inside the box.
16. Referees can add a round with unlimited time in remote-controlled mode to determine the winner in case there is none for the first 3 rounds.
17. The first robot to win two rounds, wins the game.
18. Referee's' decision is final.
Engineering Tips
1. Build wide and low and relatively heavy.
2. Use the highest torque motors available.
3. When possible use high density/high tack drive wheels or tracks with silicone treads. You need the most friction possible in order to push your opponent.
4. When available use a high gear ratio to multiply the torque being produced by the motors.
5. When possible, use either Arduino or Raspberry Pi controllers with line sensors to stay in bounds on the field.
6. Build an angled or wedged body cover to reduce impact of opponent.
7. Attack opponent from oblique angle if allowed.
8. Protect your wheels.
9. Mount your on-off switch in an easily reached, but protected location.
10. Test, Test, Test.
