neuronbot2_bringup Bringup_launch.py robot_localization
Hello, is the robot_localization mentioned in the Bringup_launch file in the neuronbot2_bringup function package included in the warehouse?
Or do I need to use a separate binary download and installation?

You can install it by typing sudo apt install ros-$ROS_DISTRO-robot-localization

I tried to use binary download, but my ros2 version is eloquent, it can't locate this package, and when I download using source code, it can't finish compiling. Ting Chang ***@***.***> 于2021年4月7日周三 下午3:11写道：

Maybe the reason is that eloquent is end-of-life, so you can't download the binary.
I have no time to test it on eloquent, if you are still using eloquent, you have to build robot-localization on your own and fix the error.

Did you download it through binary when you tested it before? Ting Chang ***@***.***> 于2021年4月7日周三 下午3:35写道：

I have forgot it...it's been a long time, almost a half year.
By the way, robot_localization is not necessary for NeuronBot, you can remove it if you don't need EKF functionality.

But if it is not used, it will always prompt that the coordinate information can not be found. I don't quite understand this. Ting Chang ***@***.***> 于2021年4月7日周三 下午4:07写道：

Hello, if it is convenient for you, can you post a rqt-graph file or tf-tree of the normal navigation node for your reference?

You have to publish the TF from odom instead of the TF from ekf.

After I executed the bringup_launch.py file in neuronbot2_bringup, I used ros2 topic echo /odom to view the data of / odom and found that it did not output data information, so when I ran bringup_launch.py in the neuronbot2_nav file, it kept warning that I could not find odom, and my tf tree could not connect to map. I am now looking for the reason.
By the way, the tf tree you posted seems to be the node of the gmapping. Can you post an information map of rqt_graph when performing navigation?

Do you have a NeuronBot? If you don't, why do you think you can receive /odom without a robot?

I deployed the program to an actual car to execute the program.
