slam problem in main.launch

See original GitHub issue

Hi, I recently bought a LoCoBot. When I was trying the examples, I run into a problem. $ roslaunch locobot_control main.launch use_base:=true use_vslam:=true use_camera:=true The error message is, [orb_slam2_rgbd-6] process has died [pid 2152, exit code -6, cmd /home/locobot/low_cost_ws/devel/lib/orb_slam2_ros/orb_slam2_rgbd __name:=orb_slam2_rgbd __log:=/home/locobot/.ros/log/39afd322-4b12-11ea-86ed-48f17fdf7f9b/orb_slam2_rgbd-6.log]. log file: /home/locobot/.ros/log/39afd322-4b12-11ea-86ed-48f17fdf7f9b/orb_slam2_rgbd-6*.log

As a result, I cannot run the navigation examples with slam involved.

Do I need to reinstall PyRobot? Because PyRobot is pre-installed on LoCoBot so I didn’t do anything with it.

@yimengli46,

Were you SSHing into the robot when running that command? If you were, did you make sure to add the ‘-X’ flag? I’ve seen a similar error to what you are describing, and it resolves itself when you do this. The ‘-X’ flag allows graphical applications on the robot computer (such as orb slam) to work. Otherwise, those applications will just crash and burn.
