Warning

The contents in this chapter corresponds to the Remote PC (your desktop or laptop PC) which will control TurtleBot3. Do NOT apply this instruction to your TurtleBot3.

Note

This instruction was tested on Ubuntu 16.04 and ROS Kinetic Kame.

5.1. Install Ubuntu on Remote PC (Desktop or Laptop PC)

[Remote PC] Download Ubuntu 16.04 on the remote PC from the following link.

[Remote PC] There are two ways to install ROS. If you prefer manual installation, please take the second method. In order to develop source code from the remote PC, please configure ROS environment after completing ROS installation.

5.2.1. First Method

Install ROS by using a simple installation script file

Tip

The terminal application can be found with the Ubuntu search icon on the top left corner of the screen. Shortcut key for terminal is Ctrl-Alt-T.

sudo apt-get update
sudo apt-get upgrade
wget https://raw.githubusercontent.com/ROBOTIS-GIT/robotis_tools/master/install_ros_kinetic.sh && chmod 755 ./install_ros_kinetic.sh && bash ./install_ros_kinetic.sh

5.2.2. Second Method

You can start from “1.2 Setup your sources.list” and keep following the instruction until “1.7 Getting rosinstall” from below ROS installation instruction link.

Note

In order to check which packages are installed, please check this link out. https://raw.githubusercontent.com/oroca/oroca-ros-pkg/kinetic/ros_install.sh

5.2.3. Configure ROS Environment

If you are going to modify or develop source code from the remote PC, you’ll have to configure ROS environment. Simple instructions are described in the below link and it will take a couple minutes.

5.3. Install dependent packages

[Remote PC] The next step is to install dependent packages for TurtleBot3 control.

sudo apt-get install ros-kinetic-joy ros-kinetic-teleop-twist-joy ros-kinetic-teleop-twist-keyboard ros-kinetic-laser-proc ros-kinetic-rgbd-launch ros-kinetic-depthimage-to-laserscan ros-kinetic-rosserial-arduino ros-kinetic-rosserial-python ros-kinetic-rosserial-server ros-kinetic-rosserial-client ros-kinetic-rosserial-msgs ros-kinetic-amcl ros-kinetic-map-server ros-kinetic-move-base ros-kinetic-urdf ros-kinetic-xacro ros-kinetic-compressed-image-transport ros-kinetic-rqt-image-view ros-kinetic-gmapping ros-kinetic-navigation
cd ~/catkin_ws/src/
git clone https://github.com/ROBOTIS-GIT/turtlebot3_msgs.git
git clone https://github.com/ROBOTIS-GIT/turtlebot3.git
cd ~/catkin_ws && catkin_make

If catkin_make command is completed without any errors, the preparation for TurtleBot3 is done.

5.4. Network Configuration
