Foxglove Studio can load local and remote ROS 1 (
.bag) files, or connect directly to a running ROS stack using a Rosbridge (WebSockets) or native (TCP) connection.
Open ROS 1
.bag files from your local filesystem or a remote cloud storage solution.
To load a local ROS 1
.bag file, double-click it from your file manager, drag-and-drop the file directly into the app, or Open local file via the Data source dialog:
Foxglove Data Platform
Check out the Data Platform docs for more information on how to export and visualize your robotics data.
To load a remote ROS 1 (
.bag) file, select Open file from URL in the Data source dialog, and enter the URL to your remote file.
Check out the Setting up CORS page for more details on loading your remote data files into Foxglove Studio.
For live connections, you must be on the same network as the robot. While we support multiple options, we recommend Rosbridge as the easiest option to get started.
Connect directly to your running ROS stack via WebSockets using a Rosbridge connection. This connection option requires only a single open port between Studio and your robot.
rosbridge connection uses a standard protocol to connect Studio to your ROS master over WebSockets. While it does require running an extra ROS node (
rosbridge_server), we recommend this option if you have a network firewall between ROS and Studio, as it requires your ROS host to have only one port open.
# For Noetic (ROS 1) $ sudo apt install ros-noetic-rosbridge-suite
Next, start the WebSocket server, and review the command printout to determine the port it is listening on (e.g.
$ roslaunch rosbridge_server rosbridge_websocket.launch
Click Open connection in the Data source dialog, select "Rosbridge (ROS 1 & 2)", then enter the URL to your Rosbridge server:
You are now connected to ROS!
To test your connection, add a Raw Messages panel to your layout, and see a list of available topics populate the dropdown. Check out the
/connected_clients topic to see information
rosbridge is publishing about your connection.
Rosbridge connections support publishing back to your ROS stack, but not reading or setting ROS parameters.
NOTE: Docker for Mac unfortunately does not expose all container ports to the macOS host, and so does not support bridge or host networking. When running ROS on a Mac, use the Rosbridge connection instead.
Connect directly to your running ROS stack via a native TCP (Transmission Control Protocol) connection to access your ROS master and/or nodes directly.
Once you have a working ROS 1 setup on your computer, run
roscore in your terminal to start your ROS master.
If you're experiencing any issues, ensure you have unrestricted network connectivity between your ROS stack and Studio, as ROS uses multiple ports to communicate.
If you're running ROS and Studio on different machines see the ROS 1 Network Setup docs to make sure your environment is configured correctly.
ROS 1 connections do not yet support reading or setting ROS parameters.
