Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. By default, geotiff maps are saved to the 'hector_slam/hector_geotiff/maps' folder. The ROS Wiki is for ROS 1. This launch file starts the hector_mapping node as well as the hector_trajectory_server and hector_geotiff nodes needed for generating geotiff maps. You should now see the mapping process in realtime in rviz. The main packages are: hector_mapping The SLAM node. Analyze these two launch files. 1) How to get the hector_geotiff_plugins to build cleanly? If you are designing a new LIDAR or you have a LIDAR different than the one on Turtlebot3, then you may need to manipulate LIDAR parameters in simulation. Let's launch hector_slam with my launch file. My hector slam used to work with this file, but not with my own bag file since the bag file I was generating didn't have any tf. To do so, first, go to the YD Lidar workspace and open the src file. 3) Afaik hector mapping doesn't use imu data (might be that they added that over the last year though). 3) I do not have an IMU to use with the hokuyo lidar but I have a turtlebot with gyro, can I launch the turtlebot launch file and use teleop to get the imu from the turtlebot utilizing its IMU? Go to the launch file for Hector-SLAM. Ubuntu 18.04LTS $ cd ~ $ sudo apt-get install ros-melodic-rplidar . sudo apt-get install ros-groovy-hector-slam. However both ways will work.

You can change necessary parameters in these files for your application. Make sure you have installed hector_slam correctly. 4. Generally people want to test hector slam with different parameters and for these situations using teleoperation to move turtlebot 3 does not make any sense since you need to move in same way for all cases to make a fair comparison. slam_methods gmapping, cartographer, hector, karto, frontier_exploration SLAM . $ roslaunch kamu_robotu_launch oko_slam.launch sim_time:=true slam_type:=hector_mapping Then play the rosbag file again. Use in place of gmapping. Then, install hector-slam using apt package manager. Are you sure you want to create this branch? 56 lines (44 sloc) 2.35 KB Correct TF tree configuration for our case can be seen below: Important NOTE: You can also use our launcher with a real data without saving as a rosbag file. That's all for the installation. I also added hector_trajectory_server to each SLAM node because I find it really useful to visualize the robot's trajectory while doing SLAM, might provide some good insights in the future . NOTE: It is a good idea to copy original xacro file if you need to use default values later. Handheld Mapping System in the RoboCup 2011 Rescue Arena. the Map type and Point Cloud type, to visualize the desired datas. We do not use any odometry information since hector slam only subscribes laser scan data. Open tutorial.launch provided by hector_slam package. (optional).
