Overview

About Robo Sumo

Autonomous robots compete by pushing each other out of the ring

Robo Sumo Competition

"Robo Sumo" is held between two autonomous robots. The objective is to push the opponent robot out of the circular ring or immobilize it. The ring is a white circular platform with a black boundary line along its perimeter.

The duel consists of three rounds, and the robot team that earns two wins is declared the overall winner. Robots operate fully autonomously; external control during the match is strictly prohibited.

01

Autonomous operation

Robot must independently detect and push the opponent out

02

Sensor systems

Use sensors to accurately detect the opponent and ring boundary

03

Strategy and tactics

Maintain position in the ring and exploit opponent weaknesses

04

Mechanical design

Design and build a robust, balanced robot structure

Rules

Robot Rules

Core requirements and restrictions for robots

01

Fully autonomous

The robot must be fully autonomous. Any external control devices are strictly prohibited. It may only be activated via start button and must remain stationary for 5 seconds.

02

Sharp objects prohibited

The robot must not be equipped with sharp blades or objects that may damage the arena or injure hands. Safety comes first.

03

Adhesive materials prohibited

No adhesive materials may be used on tires or body parts. Any material intended to stick to the arena is prohibited.

04

Sensor interference prohibited

Elements that interfere with opponent sensors are not allowed: side-opening wings, metal devices that deflect sensor signals, and conductive metallic compounds are prohibited.

Duel

Duel Rules and Positioning

1
Round 1

Opposite positioning

In the first round, robots are positioned opposite each other.

  • Robots are placed in start zones
  • After referee signal, participants start robots
  • Movement begins after a 5-second delay
  • Round lasts 60 seconds
2
Round 2

Side-by-side positioning

In the second round, robots are positioned side by side.

  • If a robot pushes opponent out - round win
  • If opponent is immobilized - victory declared
  • First to 2 wins - duel winner
Robot angle changes in the second round!
3
Round 3 (if needed)

Reverse positioning

The third round is held only if scores are tied. Robots are positioned in reverse.

  • If all 3 rounds end undecided - judges decide
  • Robot activity and tactics are evaluated
  • If draw persists - extra round is assigned
  • Judges decision is final
1st, 2nd and 3rd place winners receive certificates and commemorative prizes!
Victory

Win Conditions

How winners are determined in rounds and duels

Push out of ring

A robot that fully leaves the white circle is considered defeated. This is the clearest win condition.

Opponent immobilized

If the opponent robot stops moving or fails, victory is declared.

Judges decision

If 3 rounds end without result, judges determine the winner based on robot activity and battle tactics.

Prohibitions

Prohibited Actions

Flammable / explosive materials

Any flammable, explosive, or harmful materials are strictly prohibited

Disqualification

External control

Controlling or adjusting the robot via external force during battle

Disqualification

Creating private Wi-Fi network

Creating unauthorized Wi-Fi network or bringing unauthorized equipment

Disqualification

Leaving the ring

If a team leaves the ring before duel ends, it is considered defeated
