Interactive Markers Teleop (pre-groovy)

Description: A tutorial describing how to use rviz interactive markers for controlling the TurtleBot.

Tutorial Level: BEGINNER

Introduction

TurtleBot interactive markers are an alternative way to control your TurtleBot. They allow you to teleoperate the robot from rviz.

Running the Marker Server

Do these steps on the PC, not the TurtleBot for best performance. First, if you installed from source, make sure the package has been made:

> rosmake turtlebot_interactive_markers

Then launch the turtlebot_marker_server, which will host an interactive_markers server.

> rosrun turtlebot_interactive_markers turtlebot_marker_server

Running rviz

Next, start up a copy of rviz displaying the marker topics. On the PC, type:

> rosrun rviz rviz -d `rospack find turtlebot_interactive_markers`/config/interactive_markers.vcg

Interact!

Check the "Interactive Makers" display component and select the "Interact" tool in the tool palette on the top of the screen (shown below) to bring up the interactive markers for the turtlebot.

You can now drag the red arrows to drive the TurtleBot forward and backward, and the green circle to rotate the TurtleBot. You can also drag the green circle to both rotate and translate the TurtleBot at the same time.
