see overview slide deck for more information.

Motivation

• (Just for fun 😝)
• Getting answers against the questions directly without browsing, clicking and typing many times.
• Easy to use for everyone, especially for ROS 2 beginners and students who do not really know ros2cli.
• Multiple language support.
• Multiple LLMs support (with OpenAI Python API)

Supported ROS Distribution

Installation

Docker Container

see available images for tomoyafujita/ros2ai@dockerhub

docker run -it --rm --net=host -e OPENAI_API_KEY=$OPENAI_API_KEY tomoyafujita/ros2ai:humble

[!NOTE] OPENAI_API_KEY environmental variable is not required if using Ollama. And it is expecting that Ollama runs on the host system mostly, so that container is bound to the host network interface.
