ADAMSim ADAM mobile base — 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/mobile-robots-group-uc3m__adamsim

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/mobile-robots-group-uc3m__adamsim --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": {
    "adamsim": {
      "command": "python3",
      "args": [
        "-m",
        "mhs",
        "serve",
        "robots/mobile-robots-group-uc3m__adamsim",
        "--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

camera_angle
left_arm_joint_positions
right_arm_joint_positions

Adjusts

Nothing declared.

Actions

drive: Drive a mobile base with a commanded linear and angular velocity for a bounded duration, or to a target pose. Obstacle and zone limits are enforced by the binding safety envelope.
stop_motion: Command both wheel targets to zero through Navigation.move_wheels. The upstream exposes no wheel-velocity readback and no deceleration profile, so the receipt reports that the zero command was applied, not that the simulated base was measured at rest.

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/mobile-robots-group-uc3m__adamsim
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.

Source and evidence

Upstream: mobile-robots-group-uc3m/adamsim
Pinned commit: 85a9b1fce83a
Licence: NOASSERTION
Stars: 9
Evidence: contract_checked on the fake backend
Backends: fake

The upstream repository asserts no licence (NOASSERTION); check it before you redistribute the upstream code.

The driver package MHS/drivers/robots/mobile-robots-group-uc3m__adamsim wraps the upstream code at the pinned commit. Its REFERENCE.md documents the full contract: every value, action, unit, limit and the safety declaration.
