Invalid roslaunch XML syntax
So I've created two files: robot.launch and robot.yaml. Robot.launch contains this:
Robot.yaml contains this:
nxt_robot: - type: touch frame_id: touch_frame name: my_touch_sensor port: PORT_1 desired_frequency: 20.0
When I use roslaunch robot.launch I get:
root@joel:~/learning_nxt# roslaunch robot.launch ... logging to /root/.ros/log/ea9ca04a-da59-11e4-aa30-080027df9655/roslaunch-joel-21391.log Checking log directory for disk usage. This may take awhile. Press Ctrl-C to interrupt Done checking log file disk usage. Usage is <1GB.
error loading tag: file does not exist [/opt/ros/electric/stacks/nxt/learning_nxt/robot.yaml] XML is root@joel:~/learning_nxt#
Then when I run roslaunch robot.yaml I get:
root@joel:~/learning_nxt# roslaunch robot.yaml ... logging to /root/.ros/log/158aef32-da5a-11e4-aa30-080027df9655/roslaunch-joel-21400.log Checking log directory for disk usage. This may take awhile. Press Ctrl-C to interrupt Done checking log file disk usage. Usage is <1GB.
Invalid roslaunch XML syntax: syntax error: line 1, column 0 root@joel:~/learning_nxt#
What is wrong here? I input the contents of the file robot.yaml into http://yaml-online-parser.appspot.com/ and it says that there is nothing wrong with the text.
By the way, I am following these instrucutons: http://wiki.ros.org/nxt_ros/Tutorials... - steps (3.2), (3.3) and (3.4)
