Control AI robots with phospho

phospho (or phosphobot) is a software that lets you control robots, record data, train and use VLA (vision language action models).

Overview of phospho

• 🕹️ Control your robots to record datasets in minutes with a keyboard, a gamepad, a leader arm, and more
• ⚡ Train Action models such as ACT, π0 or gr00t-n1.5 in one click
• 🦾 Compatible with the SO-100, SO-101, Unitree Go2, Agilex Piper...
• 🚪 Dev-friendly API
• 🤗 Fully compatible with LeRobot and HuggingFace
• 🖥️ Runs on macOS, Linux and Windows
• 🥽 Meta Quest app for teleoperation
• 📸 Supports most cameras (classic, depth, stereo)
• 🔌 Open Source: Extend it with your own robots and cameras

Getting started with phosphobot

1. Get a robot

Purchase your phospho starter pack at robots.phospho.ai, or use one of the supported robots:

• SO-100
• SO-101
• Koch v1.1 (beta)
• WX-250 by Trossen Robotics (beta)
• AgileX Piper (Linux-only, beta)
• Unitree Go2 Air, Pro, Edu (beta)
• LeCabot (beta)

See this README for more details on how to add support for a new robot.

2. Install the phosphobot server

Install phosphobot for your OS using the one liners available here.

3. Make your robot move for the first time!

Go to the webapp at YOUR_SERVER_ADDRESS:YOUR_SERVER_PORT (default is localhost:80) and click control.

You'll be able to control your robot with:

• a keyboard
• a gamepad
• a leader arm
• a Meta Quest

Note: port 80 might already be in use, if that's the case, the server will spin up on localhost:8020

4. Record a dataset

Record a 50 episodes dataset of the task you want the robot to learn.

Check out the docs for more details.

5. Train an action model

To train an action model on the dataset you recorded, you can:

• train a model directly from the phosphobot webapp (see this tutorial)
• use your own machine (see this tutorial to finetune gr00t n1)

In both cases, you will have a trained model exported to Huggingface.

To learn more about training action models for robotics, check out the docs.

6. Use the model to control your robot

Now that you have a trained model hosted on huggingface, you can use it to control your robot either:

• directly from the webapp
• from your own code using the phosphobot python package (see this script for an example)

Learn more in the docs.

Congrats! You just trained and used your first action model on a real robot.

Advanced Usage

You can directly call the phosphobot server from your own code, using the API.

Go to the interactive docs of the API to use it interactively and learn more.

It is available at YOUR_SERVER_ADDRESS:YOUR_SERVER_PORT/docs (default: localhost:80/docs)

We release new versions very often, so make sure to check the API docs for the latest features and changes.

Install from source

1. Download and install uv and npm. Best compatibility is with python>=3.10 and node>=20.

2. Clone github

git clone https://github.com/phospho-app/phosphobot.git

3. On MacOS and Windows, to build the frontend and start the backend, run:

make

On Windows, the Makefile don't work. You can run the commands directly.

cd ./dashboard && (npm i && npm run build && mkdir -p ../phosphobot/resources/dist/ && cp -r ./dist/* ../phosphobot/resources/dist/)
cd phosphobot && uv run --python 3.10 phosphobot run --simulation=headless

4. Go to localhost:80 or localhost:8020 in your browser to see the dashboard. Go to localhost:80/docs to see API docs.
