ROV GUI

This is the GUI for the International MATE ROV-competition 2018. The GUI is made with React and Electron, and communicates with the ROV through ROS.

Getting started

To start the GUI, first install npm, then run:

• npm install
• npm run dev

This will start the Electron-app in development mode.

Connecting to ROS

To be able to connect to ROS, a ROS-bridge-server has to be installed:

Ubuntu: sudo apt-get install ros-kinetic-rosbridge-suite

Production

Run npm run dist. This will produce an Linux-x64 executable called rov-gui inside dist/linux/rov-gui-linux-x64/

If another platform/arch is required this can be configured in package.json.

ROS-documentation

In this section all the topics used by the GUI will be listed.

All tabs

• /is_alive (std_msgs/Empty) - Should be published to by the ROV with a rate of at least 2 Hz. Otherwise the GUI will show an error message, indicating that the ROV is disconnected.

General-tab

• /general/healthcheck/<item> (std_msgs/Empty) - For telling if a specific component of the ROV is connected, where <item> is the name of the component (e.g. IMU, manipulator, etc) in lowercase. If it is not published to with a rate of at least 2 Hz the GUI will mark the component as "Not connected".

OBS-tab

• /obs/voltage (std_msgs/Float64) - The voltage of the OBS should be published to this topic.
• /obs/angles (geometry_msgs/Point) - The angle of the OBS should be published to this topic. The z-value of the Point-message is ignored.
• /obs/data (std_msgs/Float64MultiArray) - The data received from the OBS should be published to this topic. The GUI will then display the data both as a table and as a seismograph.

Aircraft identification-tab

• /aircraft_id/type (std_msgs/String) - Publish a single letter A-F to indicate which kind of aircraft is identified by the ROV.
