Tiago example:Slam can't work

[discleave]

Describe the Bug 'TIAGo SLAM' in 'TIAGo Example' can't build the map

Steps to Reproduce

1. execute 'ros2 launch webots_ros2_tiago robot_launch.py rviz:=true slam:=true'
2. See error 'No map recieived' in rviz
3. execute 'ros2 run teleop_twist_keyboard teleop_twist_keyboard'
4. See error. I can control TIAGo by keyboard, but the map can't be built

Expected behavior I could control TIAGo to build a map.

Personally it appears to be working for me, the map topic is published for me, but I do have the LaserRangeScan warning you mention. Did you follow the install procedure described here? https://github.com/cyberbotics/webots_ros2/wiki/Build-and-Install
