BabyROS
BabyROS is a mini version of ROS built on top of the Zenoh protocol. It provides a familiar pub/sub/client/server architecture for robotics and distributed systems without the heavy overhead of a full ROS installation.
Features
- Powered by Zenoh: Ultra-low latency and high-throughput communication.
- Minimalist: No complex middleware setup; just Python and Zenoh.
- Familiar API: Designed for developers transitioning from ROS/ROS2.
Getting Started
1. Clone the Repository
git clone https://github.com/telekinesis-ai/babyros
Change directory
cd babyros
2. Environment Setup (Recommended)
We recommend using Miniconda or Anaconda to manage your environment:
conda create -n babyros python=3.11
Activate your environment:
conda activate babyros
You can deactivate your environment:
conda deactivate babyros
3. Installation
Install the package in editable mode for development:
pip install -e .
(For Inter-Device Communication) Installation
Install the Zenoh router. Documentation available in: Zenoh Docs
Usage Example
To see BabyROS in action, you can run the provided example scripts.
Publisher
Open a terminal and run:
python examples/publisher_example.py
When testing is done, kill terminal with Ctrl+C.
Subscriber
In a second terminal (with the babyros environment active), run:
python examples/subscriber_example.py
When testing is done, kill terminal with Ctrl+C.
