Every category at the championship

Key rules

• A match runs to two wins out of three rounds. A round lasts 3 minutes; with no winner by then, the round is a draw.
• After the whistle, autonomous robots wait 5 seconds before moving. Moving early hands the round to the opponent.
• A robot may expand once the match starts, but it must remain one compact entity and never split into parts.
• Shedding parts totalling more than 5 g loses the round. If both robots shed parts, the round is a draw.
• Sticky traction compounds are banned: a tyre must not hold an 80 g/m² sheet of A4 for more than two seconds.
• Downforce devices — vacuum pumps and magnets — are permitted in Mega Sumo only.
• Mega, Mini, Micro and Nano start on the official RobotChallenge chip signal; without the chip the robot cannot compete.

Scoring

• The group stage is a round robin: 3 points for a win, 1 for a draw, 0 for a loss.
• The knockout stage is best-of-three. The first team to win two rounds advances.
• Humanoid Sumo scores inside the bout instead: a knock down is worth 2 to the opponent, a slip down 1, a push out 3.
• In Humanoid, a robot that fails to get up within 10 seconds loses the bout immediately.
• Teams level on group points are separated by their head-to-head result.

Key rules

• A team fields up to 3 robots, one per team member; robots and members carry matching numbers 1–3.
• Envelope is under 20 × 20 × 20 cm. Junior is up to 1.5 kg on LEGO EV3/NXT or VEX IQ controllers with at most 9 motors per team; Senior is up to 3 kg with no equipment restrictions.
• Sucking in the ball, hiding it or fitting ball-holding devices is banned; extending parts must not exceed the ball's radius.
• One 30-second timeout per match, called by the captain. Repairs happen only in the designated area during a stoppage, 30 seconds per attempt.
• Touching a robot without the referee's permission is a yellow card. Two yellows for one member is a red, and the team plays on a robot short.
• A robot that tips over or is pushed off the field may recover on its own or with help from teammates — play continues meanwhile.

Scoring

• A try is worth 1 point: the attacking team's robot has the ball and it touches the goal-line wall in the try zone.
• A 5-point lead ends the match immediately in the leader's favour.
• Disqualifying a team for a serious offence automatically awards the opponent 5 points.
• Draws stand in the group stage; the knockout stage goes to extra time and a golden goal.
• On level scores the referee compares both teams' cards, and the team with fewer wins.

Key rules

• Starting envelope is 25 × 25 × 25 cm and up to 2000 g. Once expanded the robot may not exceed 35 × 35 cm; height is unrestricted.
• The robot may carry, grip or transport no more than 2 rings at a time.
• Up to 4 drive motors and up to 4 manipulator motors, 12 V maximum, and the robot must move on wheels.
• Control is wireless only. Junior builds from a construction kit; Senior has no restriction on materials or electronics.
• The robot enters and leaves the yellow zone only through the 30 × 30 cm gate; rings may not cross the side boundaries.
• A pole counts a maximum of 4 rings — anything above that is ignored.
• The team removes its own disabled robot from the field, and the clock keeps running while it does.

Scoring

• The red and blue poles are worth 5 points each and accept only their own colour plus yellow rings.
• Yellow poles are worth 1, 2 or 3 points per the official field map and are open to both teams.
• A yellow ring on top of a coloured ring doubles the pole. Yellow on yellow adds no further multiplier.
• Knocking an opponent's ring off is −10. Deliberately removing a ring, ramming a robot or damaging the field is a yellow card and −30.
• Points are counted only after the final whistle, and only for rings seated securely on their poles.
• Endgame — a diagonal or a square of fully scored poles — stops the match and wins it.

Key rules

• Participants are 12 years old or younger.
• The robot is built from plastic interlocking blocks only — LEGO Spike Prime, EV3, VEX IQ, micro:bit and equivalents. 3D-printed parts are banned.
• One controller and no more than 4 motors per robot. Sensor type and count are unrestricted.
• The robot must fit the START area; there is no height or weight limit.
• Task order is free: remote and autonomous tasks can be interleaved, and the robot may return to START to swap attachments.
• During an autonomous task nobody may touch the robot, the controller or the field props until the robot returns to START on its own.
• Teams get 60 minutes of debugging beforehand; a round lasts 3 minutes and there are two rounds.

Scoring

• The task sheet is worth 270 points, or 300 with the championship bonus task.
• The time bonus is (remaining seconds ÷ round length) × 30 — up to 10% of the base sheet.
• Every retry costs 5 points. A robot that sheds no parts earns 5.
• Ranking uses the better of the two rounds; ties go to the team with more time remaining.
• The referee crew tallies the sheet after the round, from the final state of the field.
