Setup

(1) Dependency installation:

sudo apt install python3-pip
python3 -m pip install inputs

(2) Clone into your ROS workspace, for example:

cd ~/ros_ws/src
git clone git@code.umd.edu:robotics-at-maryland/qubo_gui.git

(3) Build your ROS workspace:

cd ~/ros_ws
colcon build

(4) Tell rqt to find our plugins (if rqt doesn't seem to be finding updated plugin code, try running this again):

rqt --force-discover

(5) For now, run rqt from the commandline. Then load the plugins you want inside the rqt GUI.

• Click "Plugins" in the menu bar.
• Find the plugin you want.

Building and running the code

colcon build

Development

Adding or modifying a plugin

• Update plugin.xml
  • You need one <class> tag per plugin.
  • Make sure type= attribute has the correct Python import path to refer to your plugin class.

Suggested naming convention: Organize under a "Qubo" group, so that it is easy to find our custom plugins in rqt. For example:

...

<class ...>
    ...
    <qtgui>
      <group>
        <label>Qubo Control</label>
      </group>
      <label>Thruster Control</label>
      ...
    </qtgui>
  </class>
