Package version

Ubuntu 24.04 (Noble) / ROS 2 Jazzy (in my Turtlebot4)

Expected behaviour

I want to use ROS 2 Humble on my TurtleBot 4 because my user PC is running Ubuntu 22.04 with ROS 2 Humble. I expected the robot to be compatible with my current setup, or to be able to switch versions easily.

Actual behaviour

My TurtleBot 4 came pre-installed with Ubuntu 24.04 and ROS 2 Jazzy. Since my PC is running Ubuntu 22.04 (Humble), I am facing communication issues due to the ROS 2 version mismatch (Jazzy vs Humble).

Error messages

N/A

To Reproduce

1.Check the PC environment: Ubuntu 22.04 / ROS 2 Humble.
2.Check the TurtleBot 4 environment: Ubuntu 24.04 / ROS 2 Jazzy.
3.Observe that they cannot communicate properly due to the version mismatch.

Hello @25fmr06IwazakiFumiya
Thank you for reaching out on the Turtlebot 4 Github Page. If you wish to install ROS 2 Humble to your Turtlebot, you can do so by following the steps outlined here - https://turtlebot.github.io/turtlebot4-user-manual/setup/basic.html#install-latest-raspberry-pi-image

Be sure to select the Humble version of the ISO for installation onto the Raspberry Pi.

After installing the ISO to the Raspberry Pi's SD card, update the Create 3 firmware to use the Humble flavoured version - https://turtlebot.github.io/turtlebot4-user-manual/setup/basic.html#create-3

Let me know if you have any follow up questions or if I can help with anything else.
Best Regards,
