System Setup

This section outlines how to set up your OutdoorNav system for some preliminary testing with the OutdoorNav Software on a UGV. For details on simulation, refer to Simulation.

These instructions assume that the UGV is already powered ON.

Connecting to Web UI

The web server for the UI typically runs on a computer on the UGV. As such, it is necessary for the networking setup on the UGV to be complete and for all related hardware to be powered on.


In the case of Clearpath Robotics OutdoorNav Hardware, ensure that the Base Station is powered ON.

Follow the steps below to connect to the Web UI.

  1. Connect your computer to the same network as the UGV.


    For Clearpath Robotics OutdoorNav Hardware, use the Base Station network. Enter the network list and find the wireless network related for your UGV. The SSID of the network is located in the Robosmith manual that was shipped with your UGV.

  2. Open an Internet browser (preferably Chrome) on your computer.

  3. Enter the UGV's IP address followed by a forward slash in the search bar. A bookmark of this page can also be created for future sessions.


    For Clearpath Robotics OutdoorNav Hardware, this will be for normal use cases and for systems with a separate OutdoorNav computer (including the OutdoorNav Starter Kit and the OutdoorNav Backpack.

The above steps will open the Web UI, which will allow the user to operate the UGV in Manual Mode (teleoperation) or in Autonomous Mode (missions). Upon startup the user will be presented with a page that shows the End-User License Agreement. This page will be visible each time the UGV is restarted but only on the first navigation to the page. The EULA should be reviewed prior to using the system.

Loading Map Tiles

The Web UI does not cache map tiles on the browser; therefore, the user will need to ensure their computer has a connection to an Internet source to load the map tiles. There are a several options to achieve this:

  1. If the system includes a Base Station that is connected to the Internet, you will be able to access the Internet and therefore map tiles over the base station network without needing any further updates.
  2. Connect your phone via USB to your computer (or tablet) and enable USB tethering on your phone to share the Internet from your phone.
  3. Switch your computer (or tablet) to a network that is connected to the Internet, zoom in/out of the map to load the tiles then switch back to the original network.

Survey Base Station

If your system includes a Base Station, it must be surveyed using the steps below to be able to to operate the UGV autonomously.

  1. Access the Menu Settings Map.
  2. In the Survey Base Station section, click the Start button begin the surveying process.

During surveying, the Status Indicator will turn orange and return to its green default state when surveying is done . Only then should the UGV be sent on autonomous missions. The entire surveying will take approximately 5 minutes. A feedback bar will also be displayed showing the current progress of the surveying. Do not refresh the page or you will lose the feedback bar.


For an accurate survey, do NOT move the Base Station during this process. After the surveying has completed, the Base Station should not be moved unless required. If you need to move the Base Station or it has been moved accidentally, the surveying process needs to be run again.

Set Datum

Before operating the UGV autonomously, the user will need to set the datum, which is the reference point in the world coordinate frame.

  1. Access the Menu Settings Map.

  2. In the Change Datum section, enter the latitude and longitude of a location close to the test site (within 10km). Decimal lat/lon are expected. Use a minimum of 6 decimal places.

  3. Click Set Datum button to set the new datum.

    The user should see the blue dot (datum) and the blue arrow (UGV) move to the test site. If the GPS status indicators are green, the UGV should be at its correct position on the map as well as facing in the correct direction.

Set Dock Location


If the Clearpath Robotics autonomous docking package has been purchased, follow these instructions to set up the dock location. Otherwise, this section can be skipped.


Keep the area around the dock free of objects and people. There is no obstacle detection between the pre-docking point and the dock; similarly, there is no obstacle detection during the undocking operation.

Autocharge Dock

Before being able to dock the UGV autonomously, set up the dock location. Follow these steps to position the UGV in its correct position and orientation.

  1. Power ON the UGV and computer and wait for the system to finish booting. For example, on the Clearpath Robotics Husky, booting is complete when the COMM indicator turns green.

  2. Start by manually driving the UGV to the dock target and align it as straight and centered as possible so that it begins charging. The Wibotic receiver on the UGV should be centered longitudinally and laterally with the circle on the Wibotic transmitter (TR-300).

  3. Let the UGV sit in this position for 2 minutes to acquire an RTK GPS fix. The POS (position) and DIR (heading) GPS status indicators on the UI should read as follows: .

    If the GPS status indicators are yellow or red, the selected location of the dock is NOT appropriate. Please change the dock location such that the GPS antennas have a clearer visibility.

  4. On the UI, access the drop down menu on the top-left of the page, select Settings and click the Add New Dock Location button. The dock location will be stored in 5 - 10 seconds as data is collected.

If the Base Station has been moved (and therefore been resurveyed), or if the dock has been moved to a new location, the user will need to reset the location of the dock. This is done in the following manner:

  1. Repeat the previous set of instructions from step 1 to 4.

  2. While in Edit Mode select the dock on the UI. A drop down should appear with the option to reset the dock location. Select that option.

  3. After approximately 5 - 10 seconds the dock location should be updated and the UI will reflect the change accordingly.

Checking GPS RTK Fix

Each time the UGV has been powered up (or moved from a GPS-denied environment to a GPS-available environment), let the UGV sit in this position for 2 minutes to acquire an RTK GPS fix. The POS (position) and DIR (heading) GPS status indicators on the UI should be green: .

If the GPS status indicators are yellow or red, the selected location does not have an adequate GPS signal. Move the UGV such that the GPS antennas have a clearer visibility.

If using Switft Navigation Duros and/or a Clearpath Robotics Base Station, each of these will have a solid blue LED on all of them when the RTK GPS fix is acquired.

Recording a Rosbag

See the ROSbag Recorder section for details on recording ROS data either.
