The frontier_exploration demo fails quickly because the robot can't move.
I followed the instructions given at the frontier_exploration wiki page:
http://wiki.ros.org/frontier_explorat...
roslaunch navigation_stage move_base_gmapping_5cm.launch
roslaunch navigation_stage move_base.xml
roslaunch frontier_exploration global_map.launch
After I specified an exploration region in rviz, the robot will start exploring but soon it will stops.
From the rviz and stage, I observed that the robot most of the times got stuck to some obstacle and failed to recover, but sometimes it was in a open space, not close to any obstacle, and still couldn't move.
In the frontier_exploration terminal, I always saw an error message:
[ERROR] [1491936923.242211778, 124.600000000]: Failed to move
In the move_base terminal, I saw a related error message when the robot got stuck:
[ERROR] [1491936126.596561945, 221.100000000]: Aborting because a valid plan could not be found. Even after executing all recovery behaviors
Has anyone else encounter a similar issue? Do I need to change some configurations/parameters of move_base and exploration_frontier? Any suggestion or help will be highly appreciated.
