ros-mtconnect-2

A distributed digital manufacturing cell setup.

Simulation Environment Setup

  1. Clone ros_mtconnect_2 repository from MTConnect GitHub preferrably in the HOME directory.

    cd ~

    git clone https://github.com/mtconnect/ros_mtconnect_2.git

  2. Update the src/ path in the collaborationModel package inside the archetypeToInstance.py module (ln 5) accordingly.

  3. (User Preference) Update the adapter host and port information for the devices in cell.py module and in agent.cfg file in the configFiles directory of the ros_mtconnect_2 repository.

  4. Install the MTConnect Agent.

  5. Follow instructions for installation and usage on

    https://github.com/mtconnect/cppagent

  6. Update adapter host, port and device file information for the devices in the agent.cfg of the MTConnect Agent as well. Or simply use agent.cfg file in the configFiles directory of the ros_mtconnect_2 repository with an updated Devices file path (ln 1).

  7. Update the agent device file of the Agent to be combined.xml which can be found in deviceFiles directory.

Python Environment Setup

Some of these steps might not be needed if the necessary python packages are already installed.

  1. Open a terminal.

  2. sudo apt install python-pip

  3. pip install pipenv

  4. cd ~/ros_mtconnect_2/simulator

    There should be a file Pipfile here

  5. pipenv install -d

  6. pipenv shell

    This will launch the pip environment in the terminal

  7. pip install transitions doublex requests mock mamba

  8. Open a new terminal and in that terminal type:

    killall pipenv

  9. gedit ~/.bashrc

  10. Add this line to the bottom:

    export PYTHONPATH=\$PYTHONPATH:/usr/lib/python2.7/dist-packages

Unit Testing

The setup can be tested before being run. Following are the steps to run the spec tests developed for the simulator behavior.

  1. Make sure that necessary python dependencies are installed.

  2. Goto the spec/ directory.

    cd ~/ros_mtconnect_2/simulator/spec

    use as is if repository cloned in the HOME directory.

  3. Run:

    mamba *

    runs all the spec tests available for the different devices, collaboration models and interfaces state-machines and their behaviors.

Simulation

To run the simulation follow the following steps:

  1. Go to the src/ directory of the simulator/.

  2. cd ~/ros_mtconnect_2/simulator/src

  3. Run the MTConnect Agent with the updated configuration.

    agent run ~/ros_mtconnect_2/simulator/src/configFiles/agent.cfg &

  4. Run the cell.py module as follows:

    python cell.py
