@KangchengLiu Hi, I haven't encountered problems with joystick before, but I will try to help you fix it. May you comment this line 'rosrun joy joy_node & sleep 0.2;' in the trr_simulation script, and try launch it again to see whether the process die?

@KangchengLiu Do you connect a joystick to your computer?

KangchengLiu commented 5 years ago

It finally turned out that the process died because the sleep time between roslaunch trr_global_planner and roslaunch trr_global_planner was too short that my laptop can not deal with it.

You can fix it by doing roslaunch one by one or increase the sleep time in the trr_simulation script.

Thanks Gao Fei for his kind help!
