xv_11_laser_driver
Hello I want to install the xv_11_laser_driver http://www.ros.org/wiki/xv_11_laser_driver/Tutorials/Running%20the%20XV-11%20Node
when I write: rosrun xv_11_laser_driver neato_laser_publisher _port:=/dev/ttyUSB0
a message appears [rospack] couldn't find package [xv_11_laser_driver]
UPDATE 1: I tried the command . ~/cwru-ros-pkg/setup.bash in each terminal
But it gives me an other error message: ERROR [1326667355.420881814]: Error instantiating laser object. Are you sure you have the correct port and baud rate? Error was No such file or directory
When I looked in the file dev, I could not find files that are called ttyUSB
UPDATE 2: You are right the problem was the cable. Now in the "dev" I find the file "ttyUSB0", and when I put "lsusb": Bus 006 Device 003: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC But the problem is not fully resolved, when I run rviz, a message appears:
Fixed Frame No tf data. Actual error: Fixed Frame [/map] does not exist
Note: when I put the command "roscore", he writes a few lines, then: started core service [/rosout]. After it no longer gives me the opportunity to write other commands, I have to open a new terminal, where I write: rosrun xv_11_laser_driver neato_laser_publisher _port:=/dev/ttyUSB0 . Is this normal?
When I add Laser Scan, a message appears Topic: No messages received [URL=http://imageshack.us/photo/my-images/28/capture1du.png/][IMG=http://img28.imageshack.us/img28/8113/capture1du.png][/IMG][/URL]
