My advice in these situations is generally to make use of rqt_graph to make sure every topic you think is connected actually is connected. Second, you need odom data to do SLAM.

Laser2 . . There are recources like https://answers.ros.org/questions/ask/ for info about how to go about asking questions here. Actual error: Fixed Frame [. 2.) I think there has to be some kind of tf transformation which was not been there before. But, calculating odom of origin and Mecanum is different. base_linktf, rvizLaserScanvrep, cartographerTurtlebot3, RVIZNo tf data. but It is based on LDS and origin turtlebot3. You can add the odometryTopic and odometryFrame tags to your skid steer plugin and see if that will publish it. Im using a mecanum turtlebot version from the ipa. /rosout I hope everything is going great. /scan https://answers. I am attempting to implement gmapping into my gazebo rover simulation.

Now I am in another issue. Thus gmapping does not get a scan. It's also handy to keep some form of a ROS cheat sheet around until you feel more comfortable around ROS, something like this for example. Then, rostopic can be used to echo each topic the mapping process is relying on. . Therefore, I just used the source-code of the static_layer plugin and modified the interpretValue - function in order to map the value (which is due to the used occupancy grid between -1 and 100) to the full range of the layer (which should be 0-255). Press CTRL + C to stop. roswtf, rosnode list, rosnode info your_node, rostopic list, rostopic info your_topic, rosrun rqt_graph rqt_graph are just a few of the commands that should help you trace the problem down deep enought so that people can help you better. So my Rob is already publishing odom data. You mean that cloud point keeps spinning when you run the rviz in BotPc? slamscanmaprviztopicWarning "No map received", mapscantfmap, /scanscan, Failed to compute laser pose, aborting initialization ("base_link" passed to lookupTransform argument target_frame does not exist. ) So, I can see it is a very common topic where people can't generate the map due to "map not received".

Turns out the gazebo plugin was publishing to robot/laser/scan while my gmapping was subscribing to dd_robot/laser/scan. The problem you are having is not being very familiar with the tools within ros. The topic /odometry/filtered/global contains the robot's odometry with the GPS information. It seems to me that RTAB-MAP needs to subscribe to some topics but cannot find them, because I get warnings from rtab-map: By clicking Sign up for GitHub, you agree to our terms of service and // PCL specific includes /sensor_state Is it possible that my general rviz settings are wrong?

After setting up the launch file gmapping.launch and running it, rviz showed the warning: No map received. I am receiving laserscan data fine , however when starting gmapping node I am not getting any map building in rviz. Also useful for when objects have changed. Ros deffinetly has a bit of a learning curve and it might be confusing what would be useful info for debugging and what info would be neccasary to help you solve your issue.

Thank so much for the resources provided!! It provides the map -> odom tf. What I know about odometry is that it gives positional data ( correct me if I'm wrong, I've been here only for a week now) . In this video we are going to see how to edit a map (PGM file) which has been generating with the gmapping package.This is a video based on the following pos. If you set your global frame to map, you get TF errors for everything but odom. The path is the shortest possible coverage path in the corresponding graph, which contains sharp 90 turns. early_init_dt_scan_memory() Laser+.
