hls_lfcd_lds_driver error when trying to bring up turtlebot3 waffle Pi
2018-09-12 01:28:03 senake

When running 'roslaunch turtlebot3_bringup turtlebot3_robot.launch', I got the two errors below:


ERROR: cannot launch node of type [hls_lfcd_lds_driver/hlds_laser_publisher]: hls_lfcd_lds_driver


and


[ERROR] [1536681890.083161]: Error opening serial: [Errno 2] could not open port /dev/ttyACM0: [Errno 2] No such file or directory: '/dev/ttyACM0' [turtlebot3_core-1] process has finished cleanly


The terminal full output is shown below.


Could this is related to an initial failure when running the 'rosrun turtlebot3_bringup create_udev_rules' command that allows the openCR board to access the Raspberry Pi port without root permission? When I first ran it without the OpenCR board connected and before the openCR setup, it failed. I then ran it afterwards with everything connected and it seemed to work fine...
