I am running it on Ubuntu 20.04 and installed ros using following link:http://wiki.ros.org/noetic/Installation/Ubuntu

Hi @drakshayanidesai Use of this launch file requires the installation of the RealSense SDK (librealsense) and the RealSense ROS1 wrapper (which is compatible with ROS Kinetic, Melodic and Noetic).

Have you installed the RealSense ROS1 wrapper, please?

Did you build the ROS1 wrapper from source code?

If you did, were you in the catkin_ws/src/ directory when you performed the git clone instruction git clone https://github.com/IntelRealSense/realsense-ros.git

Yes I have done exactly the but same error as shown in attachment On Fri, 21 Apr 2023 22:13:40 +0530 MartyG-RealSense wrote

After performing catkin_make install, did you source the bashrc file?

echo "source ~/catkin_ws/devel/setup.bash" >> ~/.bashrc
source ~/.bashrc

[drakshayanidesai]

These two steps also completed Thanks On Sat, 22 Apr 2023 15:57:39 +0530 MartyG-RealSense wrote

Sometimes something has gone wrong in the installation process that does not have a traceable cause and the only solution is to completely delete the wrapper and start the installation process again from the beginning. This can be done by deleting the entire /catkin_ws/src catkin workspace folder.

Instead of installing the wrapper from source code, it may be easier to build librealsense and the wrapper together at the same time from packages instead of installing librealsense and the wrapper separately. This can be done with an apt-get installation with the Method 1 instructions.

https://github.com/IntelRealSense/realsense-ros/tree/ros1-legacy#method-1-the-ros-distribution

This method does not install the RealSense Viewer tool though, so would not be suitable if you require the Viewer.

Hi @drakshayanidesai Do you require further assistance with this case, please? Thanks!

Hi I have recorded a bag file using rs-record for 120 seconds. The test.bag is generated. Now I am unable to play it back. And how can I extract information from it? Regards Drakshayani On Sat, 06 May 2023 13:20:35 +0530 MartyG-RealSense wrote

Are you using rosbag play to play back a bag recorded with rs-record, please? If you are then bags recorded in RealSense SDK programs, such as rs-record, have incompatibities with ROS playback. Likewise, bags recorded in ROS have incompatibilities with RealSense SDK programs. A RealSense team member describes this at IntelRealSense/librealsense#3020 (comment)

You can record RealSense topics in ROS by performing a launch of the RealSense ROS wrapper and then using rosbag record -a to record all currently published ROS topics to a bag. It can then be played back in ROS with rosbag play
