slam toolbox rviz plugin not loading

edit

Hi @TCIII I understand you have raised an issue https://github.com/SteveMacenski/slam... as well and waiting for a response. Based on what you have described, I suggest to start with a fresh install of Ubuntu, Noetic and then install Slam toolbox and dependencies using apt. Sometimes if you try to do multiple installations, it's harder to fix than to restart. Hopefully you get a quicker resolution.

@ osliva,

Thanks for the response, much appreciated.

I am in the process of doing what you have suggested:

1) Fresh install of Ubuntu 20.04.3 on a Rpi 4B/4GB (the install process takes around 3 hrs due to the "unattended upgrade app" running in the installation)

2) There is going to be a problem installing ROS Noetic due to the fact that it is installed, as well as many other packages including Slam Toolbox, in a script called "setup-noetic.sh" that is available here at [ArloBot] (https://github.com/chrisl8/ArloBot). However I plan to manually install ROS Noetic, then proceed to attempt to install Slam Toolbox for ROS Noetic with catkin_make and see if that will work.

I get the felling that Steve does not want to deal with this issue and has moved on to Slam Toolbox for RO2.

If you look at setup-noetic.sh is an installation script with some fancy display progress status, but most of the steps are there. I suggest you follow them manually instead of running the script.

Hi @ oslivia,

Yes, I have used a word processor to take a detailed look a setup-noetic.sh and it appears that he uses the stock ROS install for Noetic and then proceeds to use catkin_make to build and install additional modules.

Therefore I plan to install ROS Noetic using the ROS install instructions and then proceed to build and install the Slam Toolbox for Noetic followed by ROS rplidar as a test of the Slam Toolbox Rviz Plugin installation.

@ oslivia,

1) Did a fresh install of Ubuntu 20.04.3 on a Rpi 4B/4GB 2) Installed ROS Noetic desktop so the install included rqt and rviz 3) Installed ros_rplidar to ensure that rviz was working and displayed the output of the RPLidar A1M8. 4) Attempted to install Slam Toolbox as follows: cd ~/catkin_ws/src/ git clone -b noetic-devel https://github.com/SteveMacenski/slam... cd .. rosdep install -q -y -r --from-paths src --ignore-src catkin_make

The build hung at the 74% point in the same place as when building the Slam Toolbox on a ArloBot setup-noetic.sh script install: "Building CXX object slam_toolbox/slam_toolbox/CMakeFiles/toolbox_common.dir/src/laser_utils.cpp.o".

So it looks like there is an issue with the "laser_utils.ccc.o" build?

My recommendation is to use apt when available but yes all the script is doing is building packages but might not have the latest links

@ oslivia,

After the catkin_make build failed, I figured what the heck and ran "sudo apt install ros-noetic-slam-toolbox" which as usual installed without issue.

Then I ran "roslaunch rplidar_ros view_rplidar.launch". The rplidar launched, followed by startup data and then rviz opened. When rviz opened, I looked at the "Panels" dropdown menu and the Slam Toolbox Plugin was not there. So I selected "Add New Panel" and when the "Panel Type" display opened, there was the "Slam Toolbox Plugin" under the "slam_toolbox_rviz folder. So I selected the "Slam Toolbox Plugin" and it was added to the "Panels" dropdown menu and appeared on the left side of the rviz display. I can turn the ""Slam Toolbox Plugin" on and off using the "Panels" dropdown menu.

I would say at this point that there is an issue with the ROS Noetic installation/packages/dependencies in the Arlobot "setup-noetic.sh script possibly?

Comments?

Exactly. That’s why I’m not fun of scripts to do this type of installations. Over time issues grow.
