Hello, I'm currently doing the tutorial teb_local_planner and now I'm trying to build a map with this tutorial. I execute all commands and at the end of this, I have problem with this command :

~/Documents/pts-info2-master/mybot_ws-base_sensors/src$ rosrun map_server map_saver -f my_map
[ INFO] [1553269724.865617557]: Waiting for the map

I never get the map and I must kill the process.

I use Velodyne, Ubuntu 16.04 with ROS Kinetic distribution. Thanks.

I run Gazebo with the robot.

To launch node for odometry roslaunch odometry_pkg start_odom.launch

then :

To launch node for laser_scan

roslaunch sensor_pkg laser_scan.launch

To launch node for point cloud roslaunch sensor_pkg point_cloud.launch

This is my rostopic list :

I tried these commands :

rosbag record -O mylaserdata /base_scan /tf

rosbag record -O mylaserdata /scan /odom /velodyne_points /tf

I kill the process.

rosparam set use_sim_time true

rosrun gmapping slam_gmapping scan:=base_scan _odom_frame:=odom_combined

rosbag play --clock mylaserdata
