Common issues with the user PC

1. ros2: command not found

Make sure you have sourced ROS2 galactic:

source /opt/ros/galactic/setup.bash

If you are building packages from source, you will also want to source the workspace:

source /path/to/ws/install/setup.bash

2. Create® 3 topics are not visible

First, check that the Create® 3 is connected to your WiFi network. You should be able to access

the Create® 3 portal by entering the Create® 3 IP address in a browser. For information on how

to connect the Create® 3 to WiFi, check the quick start guide.

If it is connected to WiFi, check if you can see Create® 3 topics on the Raspberry Pi.

If topics are visible on the Raspberry Pi, ensure that your PC has the following configuration set

for CycloneDDS:

</General>

</Domain>

</CycloneDDS>

To set this configuration automatically, add the following line to your ~/.bashrc file.

export

CYCLONEDDS_URI='<CycloneDDS><Domain><General><DontRoute>true</></></></>'

If you have set a ROS_DOMAIN_ID for the Create® 3, your terminal will have to have the same

ID. You can set the ID by using this command:

export ROS_DOMAIN_ID=#

Replace # with the ID.

If topics are not visible on the Raspberry Pi, you may need to restart the Create® 3 application

through the portal, or reboot the robot.
