I do the tutorial "Autonomous Navigation of a Known Map with TurtleBot" This tutorial assumes that we have a real TurtleBot or we can do it with gazebo turtlebot?

I am follwoing the tutorial: http://wiki.ros.org/pr2_simulator/Tut... I run the command: rosrun gazebo spawn_model -urdf -file drawer.urdf -model drawer1 -x 1.0 I take the error: [rospack] Error: stack/package gazebo not found

In http://wiki.ros.org/gazebo we are informed that package gazebo is replaced with 3 gazebo_ros_pkgs: gazebo_msgs | gazebo_plugins | gazebo_ros. So, my question is how I spawn the drawer.urdf model to gazebo?

the solution is roslaunch pr2_nav_tutorial.launch and no roslaunch ~/pr2_nav_tutorial.launch

i run the "PR2 Simulator Workshop" and in section 8.PR2 Navigation Stack Demo I create a launch script for starting all necessary navigation components, and save it as ~/pr2_nav_tutorial.launch in my home directory (user@ubuntu). When i run: roslaunch ~/pr2_nav_tutorial.launch I take: /home/user/pr2_nav_tutorial.launch] is not a launch file name. Also, i have not the pr2_nav_tutorial package.

i type "ssh hal" and i get "ssh: Could not resolve hostname hal: Name or service not known"
