AuNa Gazebo Ackermann race car — device market

Install

Three ways to run this device. Each one serves its fake backend: no instrument, no simulator install and no upstream checkout.

OpenAI4S (one command)

shell

openai4s lab add robots/harunteper__auna

Installs the device into the OpenAI4S Lab on its fake backend and starts it. First time? See setup below.

Or, in the workbench, open the Lab tab → Market → Install.

Standalone MHS endpoint

shell

git clone --depth 1 https://github.com/PKU-YuanGroup/OpenMHS.git && cd OpenMHS
PYTHONPATH=MHS/sdk/src python3 -m mhs serve robots/harunteper__auna --port 7400
# in a second terminal, from the same directory:
PYTHONPATH=MHS/sdk/src python3 -m mhs describe --endpoint http://127.0.0.1:7400

Serves the device as an MHS endpoint on port 7400 from an OpenMHS clone (Python 3.10 or later, standard library only); describe prints what it offers.

Any MCP host (Claude Desktop, Cursor, …)

mcp configuration

{
  "mcpServers": {
    "auna": {
      "command": "python3",
      "args": [
        "-m",
        "mhs",
        "serve",
        "robots/harunteper__auna",
        "--mcp"
      ],
      "env": {
        "PYTHONPATH": "/path/to/OpenMHS/MHS/sdk/src"
      }
    }
  }
}

Add this server to the host's MCP configuration and replace /path/to/OpenMHS with the path of your OpenMHS clone. The host starts the server and talks to it on stdin and stdout.

What it does

Measures

read_velocity_source

Adjusts

Nothing declared.

Actions

select_velocity_source: Select one configured multiplexer input source. Selecting OFF stops forwarding and makes the timer publish zero commands; selecting a motion source can immediately re-publish that source's cached last command.
publish_teleop_velocity: Publish one speed and steering-angle command on the teleop multiplexer input. The multiplexer caches it and repeats it at its timer rate only while the teleop source is selected. The receipt confirms transmission to rosbridge, not motion, arrival or stopping.
stop_velocity_source: Set the multiplexer velocity source to OFF, making its timer publish zero speed and steering commands. Input-free, acknowledged service call; no input is accepted during the latch.

Names as the driver declares them. Units, limits and the safety declaration are in the package's REFERENCE.md.

First-time setup

The OpenAI4S workbench with the OpenMHS lab, from a source checkout:

shell

# OpenAI4S workbench with the OpenMHS lab (source checkout)
git clone --recursive https://github.com/PKU-YuanGroup/OpenAI4S.git
cd OpenAI4S && ./setup.sh && source .venv/bin/activate
openai4s lab add robots/harunteper__auna
openai4s serve        # open the Lab tab

The standalone endpoint and the MCP server need only an OpenMHS clone and Python 3.10 or later. More in the market's getting-started guide and on the OpenAI4S host page.
