Hello community,

has somebody tried to combine RTABMAP and frontier_exploration ? How can I solve the problem of discovering an unknown area to build a map first ?

Idea:

1. discover the area with frontier_exploration and build a map.
2. navigation in a known environment with discovered map.

Does this make sense ???

Thanks for any hints or feedback.

Cheers Christian

Thank for some hints :-)

Hello community,

currently I'm trying to use ros2 crystal.

Now my question:

How is the feature of roscore and parameter server solved in ros2 ?

e.g. load urdf and verify model with rviz2

Thanks for any hints
