Hi, I am brand new to ROS and have had issues setting up my turtlebot_gazebo to just have the simulated turtlebot move around.
I am just trying to follow this tutorial: http://wiki.ros.org/turtlebot_gazebo/Tutorials/indigo/Make%20a%20map%20and%20navigate%20with%20it
But get stuck on Step 2, which is really just getting this http://wiki.ros.org/turtlebot_simulator/Tutorials/hydro/Explore%20the%20Gazebo%20world to work.
I run
roscore
roslaunch turtlebot_gazebo turtlebot_world.launch
roslaunch turtlebot_rviz_launchers view_robot.launch
Which both work fine.
Then I do
roslaunch turtlebot_teleop keyboard_teleop.launch
However, while my key presses to move the robot appear in the keyboard_teleop.launch terminal window, the robot doesn't move in Rviz.
How do I get my robot to listen to the turtlebot_telop_keyboard/cmd_vel topic if my robot only exists in simulation? Which node is the actual turtlebot?
Do I need to have
roslaunch turtlebot_stage turtlebot_in_stage.launch
be running? Because that gives me an error (Invalid roslaunch XML syntax: [Errno 2] No such file or directory: u'/opt/ros/kinetic/share/turtlebot_navigation/launch/includes/amcl.launch.xml').
