I recently started using mrpt-ros-pkg and I launched the file using:
roslaunch mrpt_reactivenav2d reactive_nav_demo_with_mvsim.launch
Everything is working fine except that I cannot get the robot to move using 2D Nav Goal on rviz.
I get the data published to /move_base_simple/goal topic, but the robot does not move.
However when I add a panel to rviz and use Teleop with the topic /cmd_vel, I can navigate the robot around (without defining goal positions)
