A First Interaction

Description: Run your first interaction with the turtlebot - chatter!

Keywords: turtlebot

Tutorial Level: BEGINNER

Next Tutorial: Visualisation


We are going to start a talker-listener pair over the robot-pc connection as described in the Interacting with your Turtlebot tutorial.


Bootstrap the turtle, i.e. launch minimal.



Install rocon_remocon to use rocon_remocon and rqt_remocon

  > sudo apt-get install ros-indigo-rocon-remocon ros-indigo-rocon-apps

RQT Remocon

> rqt_remocon



This begins a talker on the robot and a listener on the pc.


Rocon Remocon

The rocon remocon gives you the ability to connect to the running turtlebot and run the same interactions from a different master. It basically sandboxes an environment with ROS_MASTER_URI/ROS_HOSTNAME configured to the turtelbot's settings and runs whatever pc side applications need to be run (roslaunch/rosrun/chrome/qt app) inside that sandbox.

Note: This is not true multimaster as you are still running components in a sandboxed environment locked into to the turtlebot's master. It does however let you discover/cache your robot uri's and let you run without having to continually reset your ROS_MASTER_URI/ROS_HOSTNAME.
