I would like to run ORB_SLAM with my own drone. when typing roslaunch SLAM SLAM.launchin the terminal, I got an error that has never seen before as follows:

process[SLAM-1]: started with pid [13284]
terminate called after throwing an instance of 'rosbag::BagIOException'
  what():  Error opening file: 
[SLAM-1] process has died [pid 13284, exit code -6, cmd /home/htf/orb_ws/src/SLAM/bin/SLAM /home/htf/orb_ws/src/SLAM/Data/ORBvoc.txt /home/htf/orb_ws/src/SLAM/Data/Drone.yaml __name:=SLAM __log:=/home/htf/.ros/log/b3cdf97a-c6ef-11e8-bd1c-80a589d234a5/SLAM-1.log].

all processes on machine have died, roslaunch will exit

here is the launch file:

  <node name="SLAM" pkg="SLAM" type="SLAM" args="/home/htf/orb_ws/src/SLAM/Data/ORBvoc.txt /home/htf/orb_ws/src/SLAM/Data/Drone.yaml"/>


does anyone know how to fix it? thanks a lot.

I'm not familiar with orb slam, but the error is that it is failing to open a bag file. You should check your configuration to make sure that all your paths are right and that you have permissions on any directory where it's going to try to read a bag or write a bag file. Sometimes it uses the current working directory too.
