These instructions are intended for users with a netbook pre-installed with Ubuntu Precise.
Follow the generic Ubuntu instructions for a ros-hydro-desktop-full installation.
In addition, you will need to install the following debs for TurtleBot (please update this if you find any errors):
> sudo apt-get install ros-hydro-turtlebot ros-hydro-turtlebot-apps ros-hydro-turtlebot-viz ros-hydro-turtlebot-simulator ros-hydro-kobuki-ftdi
One last step if you have a kobuki base, you'll need to add Kobuki's udev rules (you'll need your sudo password):
> . /opt/ros/hydro/setup.bash > rosrun kobuki_ftdi create_udev_rules
For convenience, you may wish to source your setup.sh script from your .bashrc so that your environment is ready as soon as you log in. e.g.
> echo "source /opt/ros/hydro/setup.bash" >> ~/.bashrc
If you have overlaid your own development environment on top of the installed debs, point to that setup script instead.
