Software Requirements

The simulation system is made up of three components, and you need to install each of them. Installation is easy, but downloading and installing Webots can take a while. The three components are:

1. Webots robot simulator, version R2023b: the simulation environment. Erebus v26 does not support other versions of Webots.
2. Erebus: the worlds and the Main Supervisor, which applies the rules and calculates the score. The latest version is v26.1.
3. Python, version 3.9 or later: needed to run Erebus itself, and to write controllers for the robots. You can also write controllers in C/C++.

Minimum System Requirements

• Linux: Ubuntu 20.04 LTS or 22.04 LTS
• Windows: Windows 10 or 11, 64-bit
• macOS: macOS 11 “Big Sur” or 12 “Monterey”. These are the versions supported by Webots R2023b. Newer versions of macOS may also work: this documentation was tested on macOS 26.
• CPU: dual-core, 2 GHz
• RAM: 2 GB
• Graphics: NVIDIA or AMD graphics card with OpenGL support and 512 MB of memory

Python libraries

Erebus needs the Python libraries below. Most of them are installed automatically when it starts, but OpenCV is not, so you must install it yourself. The guide for each operating system includes this step.
