getting permissions

Question

I installed ROS on both the Robot (netbook) and the desktop computers after installing UBUNTU.

I am running a roomba, but not a 5XX or a create. I just need to CHANGE the port settings.

I tried to change a file by gedit turtlebot_node.py which was supposed to have the tty,usb0 inside. Once I changed it, it would not let me save it because I did not have permissions.

I have read the manuals and tried every which way to change it. Once I can see the port on the roomba and the kinect, then I can start doing the turtlebot, etc.

Any ideas welcome.

Answer 1

There is a parameter to set the port for the node. This is a much better solution than editing the code installed on your system. The parameter is ~port. See the turtlebot_node wiki page
