no gui.launch

[cyberbilly]

Everything seems to work up to roslaunch neato gui.launch. which yields "RLException: [gui.launch] is neither a launch file in package [neato] nor is [neato] a launch file name
The traceback for the exception was written to the log file"

Index of file:///home/bill/catkin_ws/src/neato-ros/neato/launch/include/ does not show any gui.launch.

@cyberbilly I can take a look at it next week. I took a look on my phone and don’t recall if that launch file was supposed to be included in this code or pulled in from somewhere else.

I found that /home/bill/catkin_ws/src/neato-ros/neato/launch/include/ did have a Display.launch and that worked, Once I figured out that your instructions did not cover installing rviz.

Next problem I think is actual communication over usb. I can communicate fine using a serial communication app with /dev/ttyAS0 and in /dev there is symlink to "neato" as per instructions. But base.launch fails. I will investigate that and let you know. the error is:

Okay so python doesn't come with serial so needs to be added by "sudo apt-get install python3-serial"

Then /dev/neato and linked /dev/ttyACM0 need 777 permissions.

These probably need to added to your most excellent instructions. Along with how to set up keyboard instead of joystick. I have not figured that out yet....

next problem display launch yields:
ERROR: cannot launch node of type [robot_state_publisher/state_publisher]: Cannot locate node of type [state_publisher] in package [robot_state_publisher]. Make sure file exists in package path and permission is set to executable (chmod +x)

I have to break, I'll look into this and let you know.

[cyberbilly]

problem was robot_state_publisher/state_publisher should be robot_state_publisher/robot_state_publisher. that's correct but node is already created in neatobase. So I deleted line out of neatobase.

Seems to be working now... cheers!
