Frequently Asked Questions

General

1. How do I start, pause or stop a mission?

   A mission can be started through the web user interface or through the ROS 2 API.

2. When I start a mission the UGV does not move. What could be the problem?

   There could be one of several reasons for why this is happening:

   1. Check that none of the onboard Motion-Stop actuators are activated.
   2. Check that none of the wireless Motion-Stops are engaged. This can be checked via the UI (a red Status Indicator means Motion-Stop is engaged) or the onboard UGV lights (will flash when Motion-Stop is engaged).
   3. If OutdoorNav is running on a Clearpath Robotics Warthog UGV that is programmed with a Futaba controller, then ensure that the controller is turned off. If it is on then it will be sending "no motion" commands that will be overriding the autonomy commands.
   4. Check the task settings for each Waypoint in the Mission. A missing task setting for a Move PTZ task will block the execution of the Mission it is in.

3. What version of ROS is compatible with OutdoorNav?

   OutdoorNav 2.0.0+ is developed in ROS 2 (and is built in Docker containers on top of ROS 2 Jazzy), so the recommended ROS version is ROS 2 Jazzy. Previous versions of OutdoorNav were based on ROS 1, but those versions are no longer supported.

4. Where do all the video/audio/images get saved from the mission tasks?

   All of the data that gets saved (ROSbags, video recordings, audio recordings, and saved images) gets stored on UGV's computer at the following location: /opt/onav/saved_files/...

Autonomy

1. Can I use OutdoorNav without using the UI?

   We empower customers to send mission via either the UI or our ROS 2 API. Through this API, you are enabled to write either CPP code or Python scripts where you would generate your mission.

Web User Interface

1. Why is the "Save Image" Task failing?

   Check the Waypoints that have a Save Image task in the Waypoint panel. If you see a red warning triangle beside the Save Image task it means that the settings for this task were not properly set. Set them and rerun the mission.

2. Are we able to make any changes to the UI?

   Unfortunately, users are not currently enabled to make modifications to the user interface. This feature will be available in a future release. Please direct any feature requests to Support.
