I download a package `rplidar_ros` and `launch rpliar_ros veiw_slam.launch`. And then ,sometiems it could play, but sometimes it will be died. Tomorrow, it has worked well , but tonight it show error:
[hector_height_mapping-3] process has died [pid 8937, exit code -11, cmd /home/robot2/catkin_rp/devel/lib/hector_mapping/hector_mapping
__name:=hector_height_mapping __log:=/home/robot2/.ros/log/86f925ea-bf55-11e5-b64a-000c29d3d3bc/hector_height_mapping-3.log]. log file: /home/robot2/.ros/log/86f925ea-bf55-11e5-b64a-000c29d3d3bc/hector_height_mapping-3*.log
when I restart it, for a moment it broken and show:
[hector_height_mapping-3] process has died [pid 9191, exit code -11, cmd /home/robot2/catkin_rp/devel/lib/hector_mapping/hector_mapping
__name:=hector_height_mapping __log:=/home/robot2/.ros/log/86f925ea-bf55-11e5-b64a-000c29d3d3bc/hector_height_mapping-3.log]. log file: /home/robot2/.ros/log/86f925ea-bf55-11e5-b64a-000c29d3d3bc/hector_heigh
