Are you ready for a challenge?
The Advanced Sumobot Competition is for anyone who has competed in a Sumobot Competition in the past, or believes they have the knowledge to compete in a more difficult competition.
Once you’ve competed in the Advanced Competition, you CAN NOT enter a Beginner Competition.
Team Fees: $40
- Teams must show respect to SumoBot organizers and to each-other.
- Insults will not be tolerated. Neither will cheating.
- Penalties range from verbal warnings to complete disqualification based on the severity of the infraction.
- If a team believes they have been unfairly penalized, their representative may appeal to the referee when the round is over.
- If the referee chooses not to revoke their penalty, the team will just have to deal with it. Any further objections may lead to additional penalization.
A team whose robot does not meet these specifications may be permitted to compete in the round robin competition if their failure to meet these specifications DOES NOT result in the possibility of damaging the other competitor’s robots. If the judges decide that the failure to meet the specifications do not result in an advantage, the team may be permitted to participate in the finals, unless another team whose robot meets these specifications has a comparable round robin score. For these rules we shall consider two scores comparable if the smaller score is greater than or equal to 80% of the larger score.
- The Robot cannot be larger than 20 cm by 20 cm before the match begins. (Yes, your robot can expand as long as it does it on its own).
- The robot cannot weigh more than 3 kgs.
- The robot must not affect the terrain of the ring. For example, your robot cannot spray liquid on the ground to slip up its opponent.
- The robot cannot damage its opponent directly. Only pushing and lifting are allowed; no hitting or stabbing. Magnets are banned due to how they affect electrical components.
- Adhesives are a bit of a sticky subject. We would prefer if you didn’t use them, as they provide unfair advantages. Please contact us if you are thinking of using adhesives (on wheels, external of robot, etc).
- Robots must be completely autonomous. No off board instructions or
- Jamming devices, such as IR LEDs intended to saturate the opponents IR sensors, are not allowed.
- Parts that could break or damage the ring are not allowed. Do not use parts that are intended to damage the opponent’s robot or its operator. Normal pushes and bangs are not considered intent to damage.
- Devices that can store liquid, powder, gas or other substances for throwing at the opponent are not allowed.
- Any flaming devices are not allowed.
- Devices that throw things at your opponent are not allowed.
- Sticky substances to improve traction are not allowed. Tires and other components of the robot in contact with the ring must not be able to pick up and hold a standard 8.5” by 11” sheet of paper for more than two seconds.
- Devices to increase down force, such as a vacuum pump or magnets, are not allowed.
- All edges, including but not limited to the front scoop, must not be sharp enough to scratch or damage the ring, other robots, or players. Judges or competition officials may require edges that they deem too sharp to be covered with a piece of tape.
- The ring is 154 cm in diameter. It is made of hard, smooth wood.
- The ring is painted black with a white border. The border is 2.54 cm thick.
- 10 cm away from the centre of the ring on either side, there are two vertical brown lines, both of which are 20 cm long and 2 cm thick.
The goal for each robot is to push or carry its opponent out of bounds. As soon as either robot TOUCHES beyond the ring’s white boundary line (any surface that is not the ring, if the robot is hanging outside of the ring but not touching the floor then that is fine), the match ends and a winner is declared. A single round consists of 3 matches between matched up teams. A win will reward you 2 points, a winning by draw 1 point, and a loss (by any means) is 0 points.
One person from each team will be chosen as their team’s representative. Representatives are responsible for placing their team’s robot inside the ring, as per the referee’s instructions. These will also be the main person of contact with the referees, so make sure to pay attention to announcements during competition.
First, teams must choose their robots’ starting positions. Robots can be placed anywhere between the white boundary line and the brown starting line on their side of the ring. For the first match whichever team has the worse rank will place first, followed by the higher ranked team. For each of the subsequent match whichever team won the previous match, will place first.
Once both robots are in place, the referee will signal both representatives to activate their robots simultaneously. The representatives must then leave the area around the ring (will be clearly marked) as to not interfere with sumobot sensors. No one from either team is allowed back in. Make sure the referee knows you’ve activated your robot.
Upon activation, both robots will sit still for 5 seconds, then start moving. If a robot moves too early, or if after 7 seconds (including the first 5) it has not moved at all, the match will be reset. If neither robot has been pushed out of the ring after 45 seconds the match will be reset. The “fault” of the reset will be determined by the referee, based on which robot he or she determines to be most likely to win that match. Each team will have 1 free “fault” per round. After a teams first fault, if they are at fault for another reset, the match will count as a loss for that team. Teams only get ONE reset each; In the event that both teams have to reset twice the match will end in a draw, with the higher ranked team getting a draw point.
The referee can, at any time and for any reason, choose to stop the match. If this happens, the referee will direct each team’s representative to retrieve their robots and prepare for a rematch.
Once the round robin event is completed teams will move to the elimination event. This is a double elimination style bracket, meaning that you are only disqualified if you lose TWO matches. All teams will start off in the “Winning” bracket. Once a team has recorded a loss they move down to the “Losing” bracket. The finals will be the champion of the “Winning” bracket and “Losing” bracket.
Teams will be seeded based on points accumulated in the Round Robin round. In this stage draws will be decided by the point totals of each team NOT their Presentation rankings.
