Hi all, I'm facing a problem using the slam_toolbox package in localization mode with a custom robot running ROS2 Foxy with Ubuntu 20.04 I've been looking a lot about how slam and navigation by following the tutorials on Nav2 and turtlebot in order to integrate slam_toolbox in my custom robot. Melodic #326 Noetic #325 Are you performing any recording? Thank you for helping me reach full functionality with my realsense cameras. I receive message. Noting that the documentation for slam_toolbox refers to ROS2 Eloquent but not the Foxy version that you are using, I wondered whether the issue may be related to Foxy.

Why do quantum objects slow down when volume increases? If this is not the appropriate place to ask for help, I can take this over to rosanswers, but I'd appreciate any insight you might have! I used the robot localization package to fuse the imu data with the wheel encoder data, set to publish the odom->base_footprint transform, then, the slam toolbox creates the map->odom transform. When set to true, this setting gathers the closest frames of different sensors to be sent with the same time tag. filter f_not_ldap { not match ("slapd" value (PROGRAM)); }; log { source (s_udp); filter (f_not_asa); filter (f_not_dbg); filter (f_not_ldap); destination (d_messages); destination (d_logserver); }; But those slapd entries are still going to my remote log server. Got it. @MartyG-RealSense I do have access to an L515 as well. Thank you for your help! As mentioned above though, a calibration is not required in order for IMU data to be displayed in realsense-viewer or rs-motion. Does illicit payments qualify as transaction costs?

Hi @MartyG-RealSense, I've been experimenting with the robot_localization package. I'm pretty new to ROS2, so I have been trying to do simple mapping with a turtlebot3 using slam toolbox. If calibrating the imu is the only way to get it functioning within ros, then I will follow the linked guide or use an external imu, but I'd like to avoid making too many changes to my current setup if possible. To understand why I needed to do this I went through Link [2] which led to Link [3]. using ros2 topic echo /camera/imu reveals that no odometry data is being published.

I am able to echo data from /camera/gyro/sample and /camera/accel/sample though, so perhaps the odometry from the L515 will be more viable for SLAM? Are you performing any recording? Hi, This is a ROS2/message filter-TF warning, not something from slam toolbox. When the robot starts to move, the lidar readings update, but the map itself does not. I may open a new issue later if I find that I also need the D435i imu functioning, but with the L515 imu working, I don't suspect that will be a problem. I didn't get what you did. It's crude, but I simply added these three static transform publishers to my launch file (which is a combination of one provided by an existing RPLidar ROS2 fork and Link [4]) and ceased having errors completely: Please start posting anonymously - your entry will be published after you log in or create a new account.

I've tried unplugging and replugging the camera in after starting the node, and the warning persisted, and the only way I am able to obtain imu data in ros is still from topics /camera/accel/sample and /camera/gyro/sample Perhaps there is a way to utilize these topics through remapping or using some other package that subscribes to these topics. When building from source on Jetson I would recommend using -DFORCE_RSUSB_BACKEND=true to build librealsense with the RSUSB backend, which is not dependent on Linux versions or kernel versions and does not require patching. ros2 launch slam_toolbox online_sync_launch.py, In rviz I add /map topic, no map received.

I'm pleased to hear that you resolved your RViz warnings and look forward to your next test results. I'll look into this, as I am receiving warnings from RVIZ. Going back to your use of JetPack 5 for its Ubuntu 20.04 support, the most recently supported JetPack in the RealSense SDK is L4T 32.6.1 (JetPack 4.6). In their case though, the reason given was 'discarding message because the queue is full' instead of 'unknown'. Could not providing a transform for the scanner frame be the issue? SLAM algorithm implementation in C++ that's compatible with windows? I looked to calibrate the imu, as I have not done that yet, but I was unable to run the calibration script as I did not install librealsense with pyrealsense2. odom->base_footprint.

Thank you for the information! privacy statement. for reason 'Unknown'" External Requests rviz2, error padin September 11, 2022, 5:15pm #1 I'm just following the Turtlebot3 tutorial and running the SLAM node. Thanks for all your help! Robot is Clearpath husky with Velodyne VLP-16 lidar, IMU and GPS sensor in gazebo. The RealSense user in that case did report though that they had to repeat the unplug-replug each time that they started a new roslaunch. Have a question about this project? To see the IMU data you should click on the '2D' option. Once I understood how ROS2 launch files work I was able to follow Link [4] to get SLAM Toolbox working with RViz and to develop a simple launch file for a custom "launch everything" package. I am facing the same problem right now. Already on GitHub? There was also a case of ROS Motion Module Failure at #1960 (comment) where the cause of the failure may have been related to doing a rosbag record of a lot of topics, as reducing the number of topics being recorded apparently solved the error. Thank you for helping me get this far! I think your best bet is filing a question on ros answers. The text was updated successfully, but these errors were encountered: Hi @RNorlie At the ROS Answers link below there was another person with a Jetson Xavier NX who experienced the Message Filter dropping message: frame 'camera_depth_frame' warning with a RealSense D455 camera, the SLAM Toolbox and depth_image_to_laserscan. I can also get one or two frames of a map to be built. This camera does not have the Motion Module Failure message, but it does display this message upon launching the node. I don't know if this is important but just to have everything in: I am filtering my lasermessage with an own node so it produces only 180 scan instead of 270. Your results make sense. Some RealSense users use a tool called Kalibr for IMU calibration. Long term Objective: Provide gps co-ordinates as goal / way points and autonomously navigate robot to the destination with the help of Nav2 stack by using slam_toolbox I also have neither an "odom_frame" nor a "base_frame" in my current setup, which appears to be required. to your account. Where and how do SLAM algorithms keep a map? the rs-motion demo was functioning just fine on my previous build, but I wasn't able to get imu data inside a node or in the realsense-viewer. Please assist. So I could not rule out that the ROS problem with IMU data is related to use of JetPack 5.
