  Hi A Dhesi2  Could you first try adding the term initial_reset:=true to your roslaunch statement please to perform a hardware reset of the camera at launch.  Just doing this one action can sometimes help to resolve problems that occur at the time of launch.

  roslaunch realsense2_camera opensource_tracking.launch initial_reset:=true

  Is this case a continuation of when you were trying to get the D435i SLAM opensource tracking to work with Raspberry Pi 4 please?  Or are you using a different computer now?  Thank you.

  My understanding of your current position based on these two case links is that librealsense and the ROS wrapper are working fine but you are not able to get working the D435i SLAM project that uses roslaunch realsense2_camera opensource_tracking.launch

  https://github.com/IntelRealSense/realsense-ros/wiki/SLAM-with-D435i 

  It does not look as though we discussed the Kimera SLAM solution  by MIT SPARK Lab on either of the above two links.  Would there be a possibility of using it instead of the RTABMAP SLAM system?  Apologies if we have discussed this before on a different case

  I have completed the instructions for https://github.com/MIT-SPARK/Kimera-Semantics and recieved the following:

  

  Are all three modules from https://github.com/mit-spark/kimera required to run this?

  There are four modules to Kimera that are installed by three links (as one of the links installs two of the modules).

  I have not personally used Kimera so I cannot provide guidance about the next step.  You may find useful an in-depth tutorial video provided by Kimera though.

  Discussion about using Kimera with RealSense starts at the 12 minute point in the video.
