RoboCON 2017 Sumobot Competition Registration is open!

April 22nd, 2017 - Chicago


Screen Shot 2017-02-07 at 4.23.44 PMThe mission of the RoboCON is to increase public awareness in STEM. We believe that every student has the potential to shine in science, technology, math, and engineering; therefore, we encourage students to share their experiences, talents, and abilities with others through this unique platform. RoboCON is a robotic sumo contest, two autonomous robots attempt to push each other out of a circular arena using mechanisms, cunning, and brute force. We welcome your participation and support in this year’s event.

Registration deadline: April 14, 2017
Competition date: April 22, 2017

Team Rules:

  • A team may have minimum two members of any K-12 grade.
  • A team can participate with one robot.
  • Robots cannot be shared among teams
  • A student cannot be a member of different teams.
  • Registration is first come first serve basis.

Robot Rules:

  • Robots must be constructed only out of LEGO-manufactured parts. No third-party parts or sensors are allowed. The parts must be unaltered and unmodified. NXT or EV3 brick can be used.  Combination of maximum four sensors of any type. (Ex. 2 touch, 2 light sensors; 1 touch, 2 light, 1 ultrasonic sensors) Once the robot is registered, sensors cannot be substituted with a different type of sensor. Motors: Up to three motors even if EV3 is used. Unrestricted non-electrical parts.
  • Programming/Software: Any programming language may be used, including, but not limited to, RCX Code, NXT code, NQC, Robolab, ROBOTC, and Visual Basic.
  • Multiple programs on the CPU are allowed. During a match, programs may be switched during the breaks between rounds.
  • Use of suction, glue, “sticky wheels,” magnets, or other methods of increasing downward force is not allowed.
  • Robot dimensions are: Maximum Width: 12 inches; Maximum Length: 12 inches; Maximum Height: No height limit; Maximum Weight: 3 pounds
  • All sumo-bots must comply with the size limitations at the beginning of a round, but can expand beyond 12x12 after a round begins.
  • Robots must be started manually.
  • Robots must operate completely autonomously, acting independently of humans or external host controllers.
  • Bluetooth must be turned off.

The Tournament:

  • The team registrations and hardware control will begin at 9:00 am. The first matches will begin at 10:00 am.
  • Teams who do not register on time and are not present at their match time will be marked as lost/eliminated.
  • Teams will be divided into groups and will play one game against each other. The top teams will move on to the next stage. Number of groups will be determined and posted according to the number of registrations.
  • Matches (a game) will consist of maximum three (3) rounds. A round is over after two (2) minutes or after one “Win” occurs.
  • There will be a 90 second break between the rounds to allow some time to fix the broken parts and/or switch programming. During the breaks, robots or programming cannot be modified.
  • Teams may do any updates to the robot at their pit area only when they are not competing.

The Play:

  • At the beginning of a match, the robots will be placed parallel on the ring about 5 inches apart and an equal distance from the center of the ring.
  • When both contestants are ready, the ring judge will signal the match at which time the robots must be manually activated by pressing a button on the brick.
  • All robots are required to have a five (5) second start delay.
  • Robots will begin their initial movement in opposite directions.
  • Robots must touch to the white border before it moves any other direction.
  • Players must clear out of the Ring Area once the robots have been activated.
  • The winner either pushes the opponent out of the ring completely or the opponent leaves the ring on its own. Hanging on the edge does not disqualify the robot.
  • When any of “major parts” (any one of motors or brick) of one robot falls off the edge and touches the floor or it becomes disabled for any reason, the other robot will be declared winner.
  • If the judge decides a robot is disabled beyond repair in 90 seconds during a round, the other robot will be declared as the winner of the match.
  • A team gets Two (2) points for “win”; One (1) point for “draw” (at the end of the two (2) minute round and no winner) and Zero (0) for “loss”
  • If it is determined by the judge that both robots are stuck in an entanglement or deadlock for at least fifteen (15) seconds, the judge will call for a Reset.
  • If the judge declares a Reset, the clock is stopped, the robots are put back in starting position, and the robots are reactivated and clock restarted.
  • At the end of the match, the points will be totaled and a winner will be determined.


  • A single judge will oversee each round as well as timing.
  • In any round, the judge has sole discretion in any dispute. The judge’s decision is final.
  • The judge has the authority to remove a participant at any time. This can be due to harmful violence, disregard for the rules, poor sportsmanship, or any other reason that the judge declares.
  • Intentional damage to the opponent robot or the robot arena is prohibited. Robotic sumo is a game of pushing, not destruction. Everything from flame-throwers, to sharp objects, to liquids is absolutely and entirely prohibited.
  • The officials and/or Judges will disqualify any robot whose strategy or operation is considered dangerous.



The dohyo will be used is a circle of 4' diameter. The doyho can be downloaded and printed at a printing office such as Kinko's. It should be printed on a matte vinyl material.
