IROS 2023 Simulated Humanoid Robot Wrestling Competition

IROS 2023 Simulated Humanoid Robot Wrestling Competition

Following-up the successful ICRA 2023 edition with the participation of 69 teams, we would like to invite you to participate in the second edition of this competition that runs online from today until the finals to be held at IROS 2023, Detroit USA on October 2-4, 2023.

This competition focuses on the development of advanced humanoid robot control software for a wrestling game. It relies on a calibrated simulation model of the NAO robot, running in the Webots simulator with realistic physics, sensor and actuator simulation. Being spectacular and easy to get started with, this competition aims at gathering a large number of competitors, both on-site and remotely. The fully open-source competition software stack was designed to be re-used as a template for other simulation-based robot competitions.

The leader board and 3D games playback are available here:

Important Dates

  • June 23rd, 2023: registration opens and qualification games start
  • September 19th, 2023: selection of the best 32 teams
  • September 26th, 2023: code freeze for the finals

The winning team will receive one Ethereum crypto-currency (priced around USD 1,876 on June 23rd, 2023).

ROS 2 integration

Each robot controller runs inside its own Docker container. Therefore you can easily embed your favorite ROS 2 image including the webots_ros2 package to communicate with Webots and power your robot controller with the best of the ROS 2 ecosystem. Two examples of robot controllers using ROS 2 Vulcanexus images are provided here and there. Alternatively, you can program your robots directly in Python, C, C++, Java or Rust.

How to participate?

Follow the instructions here: GitHub - cyberbotics/wrestling: Humanoid robot wrestling competition.
Participation is free of charge, including the finals.


We are going to continue developing our robot’s controller (MechaCheetahs) from ICAR into this Competition: IROS!
Thank you dear Olivier!
