Is it possible to check whether odom has to be transformed with tf? But, calculating odom of origin and Mecanum is different. I do seem to have my gmapping node subscribing to laser scan. If a site does not offer an RSS feed, more often than not, they lose me as a reader and subscriber. early_init_dt_scan_memory() You say you are "receiving laserscan data fine", so I would start there. . ubuntu16+turtlebot2+kinect V2. we have release turtlebot3_bringup package.

You mean that cloud point keeps spinning when you run the rviz in BotPc? If you set your global frame to map, you get TF errors for everything but odom. the skin steer plugin is publishing on cmd/vel topic and the base_frame is set to base_link I mean the chassis.. 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. It uses laser scan data and odometry data from the Turtlebot to feed a highly efficient Rao-Blackwellized particle filer to learn grid maps from laser range data. Which means nothing is publishing your odometry (if you don't know what odometry is, please let me know and I'll explain). I am attempting to implement gmapping into my gazebo rover simulation.

As such, I included all of the files in regards. This is not enough information to help you. Gmapping needs the tf from odom to your lidar, to determine how the sensor data relates to the map that it's making. I think there has to be some kind of tf transformation which was not been there before. /*# sourceMappingURL=https://www.redditstatic.com/desktop2x/chunkCSS/IdCard.ea0ac1df4e6491a16d39_.css.map*/._2JU2WQDzn5pAlpxqChbxr7{height:16px;margin-right:8px;width:16px}._3E45je-29yDjfFqFcLCXyH{margin-top:16px}._13YtS_rCnVZG1ns2xaCalg{font-family:Noto Sans,Arial,sans-serif;font-size:14px;font-weight:400;line-height:18px;display:-ms-flexbox;display:flex}._1m5fPZN4q3vKVg9SgU43u2{margin-top:12px}._17A-IdW3j1_fI_pN-8tMV-{display:inline-block;margin-bottom:8px;margin-right:5px}._5MIPBF8A9vXwwXFumpGqY{border-radius:20px;font-size:12px;font-weight:500;letter-spacing:0;line-height:16px;padding:3px 10px;text-transform:none}._5MIPBF8A9vXwwXFumpGqY:focus{outline:unset} Press CTRL + C to stop.

I tried: /sensor_state The path is the shortest possible coverage path in the corresponding graph, which contains sharp 90 turns. Because navigation package subscriber only odom topic. I designed my own robot with a lidar and a kinect. If the mapping node is not listed as a subscriber you need to remap the topic in the mapping launch file. /reset Please help me find my mistake. Doublecheck what you subscribe to in rviz to actually get the scan. no map received. So my Rob is already publishing odom data. I am receiving laserscan data fine , however when starting gmapping node I am not getting any map building in rviz. /odom I also launched the realsense_camera nodelet (lr200m_nodelet_default.launch), which outputs depth and rgb related topics (amongst others). But when i try to scan with the same lidar connected to my BotPc i got strange rotational shift effects. Please turn the [ros.gmapping.message_notifier] rosconsole logger to DEBUG for more information. I am also getting an additional warning : "No map received". I am glad your problem has been resolved.
