If you disable the map, global map, and local map in the RVIZ Displays, you can view just the laser scan: The white squiggles are a simulated laser scan using the 3D point cloud data from the 3d sensor. Anker. In a new terminal, run: After you have subscribed to the correct topic, you should see the generated map by gmapping: Wiki: stdr_simulator/Tutorials/Create a map with gmapping (last edited 2018-01-26 19:07:34 by TullyFoote), Except where otherwise noted, the ROS wiki is licensed under the, stdr_simulator/Tutorials/Using turtlebot for teleoperation, Start stdr_obstacle_avoidance node to move the robot autonomously. On the Master Computer, open a new terminal and type: Drive the Turtlebot around slowly in a circle until the green arrows are closer to the Turtlebot, Select the 2D Nav Goal button on the top bar and draw the location that you want the Turtlebot to travel to. example for save your map : http://wiki.ros.org/slam_gmapping/Tut. The laser scan is generated by taking the point cloud from the 3D sensor and grabbing points from an eye-level prespective of the robot. is it exactly 0.05000 ? The ROS Wiki is for ROS 1.

On the Turtlebot, open a new terminal and type: In RVIZ, you will see the Turtlebot with a bunch of green arrows which are hypothesis of the position of the Turtlebot, Select the 2D Pose Estimate button on the top bar and draw the location that the Turtlebot is most near. map, odom, robot footprint are not aligned in RViz. And then, when I did teleop by keyboard, I could see changing robot location. The map_saver on Eloquent is also available. When I am doing mapping then save it by: map_server map_server -f 'location' It gives me a warning that . updated Apr 7 '16 I am learning about mapping. Hi.

I finished this project now (it was a summer project), but I'm certain I had set the right resolution. Drive the Turtlebot around your map using the keyboard_teleop, and visualize the collected data in RVIZ. Saving the map using map_server Once you have a complete map or something acceptable, you can save it to use it later in the navigation stack. after that process, you can use amcl launch file as add your map (with your map name) in launch file.

You need to first save your map after mapping with gmapping. On Turtlebot, start the gmapping_demo.launch, the gmapping_demo.launch automatically launches 3dsensor.launch, On the master computer, start keyboard teleop. Also, just making sure, have you created /tmp folder ? Gmapping doesn't automatically save the map file for you, so you'll need to save it while gmapping is running. Congratulations.
