Neato and ROS error

[G. Kudryavtseva]

Dear All,
I have recently got the neato_node running on my XV-11. However, when I launch roslaunch 2dnav_neato move_base.launch I get the following error:

[move_base-3]process has died[pid 5064, exit code -4]. log files /home/boris/.ros/log/(bunch of numbers i'm not going to write down)/move_base-3*.log

Thanks,

Boris.

So, this error message tells you a lot already:

If you change directory to /home/boris/.ros/log/(bunch of numbers) you will find a log file for move-base (called move_base-3.log  ... in there, you should have some error message that specifies why it has died.

The problem is, there is no such file "move_base-3.log" in the directory /home/boris/.ros/log/(bunch of numbers).

However, there is a file "neato-3.log" that has error messages:

Hello Boris,
What is your USB port? "~/ttyUSB0" or "~/dev/ttyACM0"?
 
- Camp

 

[mamagelia]

It's /dev/ttyACM0. I tried using /dev/ttyUSB0, that didn't work. So I
tried using "sudo chmod a+rw /dev/ttyUSB0" . I get: chmod: /dev/
ttyUSB0 - No such file or directory. I had to change the port in
neato.py code for it to work... However, the move_base.launch still
doesn't work. Same errors.
