My NAV2 demonstration

General Discussions
1

I’ve finally got NAV2 working and have a simple demonstration of it running.

I don’t go into the BrickPi3+ very much as it is aimed more broadly, however it is really meant for those whose robot uses a ROS2 Control Differential Drive Controller.

Here’s the link: GitHub - jfrancis71/ros2_nav2_demo: Demonstration of how to use the ROS2 Nav2 stack for navigation

There’s a link in the repo to a YouTube video where I go through it (including my mistakes…)

Hope this might be of interest. I welcome feedback, either here, or on the Discussions tab (which I’ve added) on github, so that would also work.

One way to fix the “start rviz2 before nav/slam” is to force the map server to republish the map:

Thank you. I have just tested your ROS2 service call and am happy to say it works. I think I should reword that part of my git repo.

Would you be happy for me to make an acknowledgement for this in the repo? And if so do you have a preference on how to do so? eg Profile - cyclicalobsessive - Modular Robotics Forum or a github link?

Thanks

Julian, Don’t worry about it - my reward is hearing that it worked.

I am also really happy to read of another person exploring ROS 2 with a DI/ModRobotics flavor robot. It takes a lot of courage to climb the ROS learning curve to successful mapping and navigation. Congratulations on your effort and success.

Ok, thanks. I’ll reword it anyway (in the next couple of days).

I’ll put my acknowledgement here instead. Thanks great tip!

I’ve added your suggestion to the repo (its under technical notes).

BTW I think I’ve found your youtube channel. Great content and very nicely edited.
