The high level of English is a standard for a top student.
1. Everybody has difficult years, but a lot of times the difficult years end up being the greatest years of your whole entire life if you survive them.
2. The lucky ones inevitably do not have best of the best. They seek simply the best of what they see on their journey.
3. Do you want to take a leap of faith or become an old man，filled with regret，waiting to die alone？
4. Sometimes you need patience in order to find true happiness. It won't come fast and it won't come easy, but it will be worth it.
5. Take risks. If you win; you will be happy. If you lose; you will be wise.
6. The reason for people’s traveling is not just to reach a destination, but to enjoy all kinds of pleasures in the journey.
7. Self-confidence leads to success and mind determines destiny.
8. You can’t live your life for other people. You’ve got to do what’s right for you, even if it hurts some people you love.
9. Your present circumstances don’t determine where you can go; they merely determine where you start.
10. I will live in a house towards the sea, with spring blossoms.
11. No matter how hard the past is, you can always begin again.

1. Ros Setting
(1) The following command needs to be executed every time we open a new terminal window in order to apply the settings to current terminal window.
$ source /opt/ros/kinetic/setup.bash
$ source ~/catkin_ws/devel/setup.bash
(2) To avoid this repetitive task, we can set it to import a setting file when we open a new terminal window every time Additionally, we can configure the ROS network and create quick commands for frequently used commands.
$ gedit ~/.bashrc
# Set ROS Kinetic
source /opt/ros/kinetic/setup.bash
source ~/catkin_ws/devel/setup.bash
# Set ROS Network
export ROS_HOSTNAME=xxx.xxx.xxx.xxx
export ROS_MASTER_URI=http://${ROS_HOSTNAME}:11311
# Set ROS alias command
alias cw='cd ~/catkin_ws'
alias cs='cd ~/catkin_ws/src'
alias cm='cd ~/catkin_ws && catkin_make'
$ source ~/.bashrc

[Description]
This book is a ROS robot programming guide based on the experiences we had accumulated from ROS projects like TurtleBot3, OpenCR and OpenManipulator. We tried to make this a comprehensive guide that covers all aspects necessary for a beginner in ROS. Topics such as embedded system, mobile robots, and robot arms programmed with ROS are included. For those who are new to ROS, there are footnotes throughout the book providing more information on the web. Through this book, we hope that more people will be aware of and participate in bringing forward the ever-accelerating collective knowledge of Robotics Engineering.
[This Handbook is written for]
College students and graduate students who want to learn robot programming based on ROS (Robot Operating system) and also for professional researchers and engineers who work on robot development or software programming.
We have tried to offer detailed information we learned while working on TurtleBot3 and OpenManipulator. We hope this book will be the complete handbook for beginners in ROS and more people will contribute to the ever-growing community of open robotics.
