TIP: If you want to launch Lidar sensor, Raspberry Pi Camera, Intel® RealSense™ R200 or core separately, please use below commands.

• $ roslaunch turtlebot3_bringup turtlebot3_lidar.launch
• $ roslaunch turtlebot3_bringup turtlebot3_rpicamera.launch
• $ roslaunch turtlebot3_bringup turtlebot3_realsense.launch
• $ roslaunch turtlebot3_bringup turtlebot3_core.launch

NOTE: If lost sync with device error message is displayed on the terminal window, the sensor device of TurtleBot3 might not be securely connected.

Load a TurtleBot3 on Rviz

[Remote PC] Launch robot state publisher and Run RViz.

TIP: Before executing this command, you have to specify the model name of TurtleBot3. The ${TB3_MODEL} is the name of the model you are using in burger, waffle, waffle_pi. If you want to permanently set the export settings, please refer to Export TURTLEBOT3_MODEL page.

$ export TURTLEBOT3_MODEL=${TB3_MODEL}
$ roslaunch turtlebot3_bringup turtlebot3_remote.launch

One a new terminal window and enter the below command.

$ rosrun rviz rviz -d `rospack find turtlebot3_description`/rviz/model.rviz

In the next chapter, you will be able to test TurtleBot3 with various teleoperation methods and run various applications.
