[ROS Amazing Contributor Badge]
I am honored and grateful to have received the prestigious ‘ROS Amazing Contributor Badge’ an accolade granted to only 20 individuals globally by the ROS community.
The ROS Contributor Badge is categorized into three levels—Contributor, Great Contributor, and Amazing Contributor—based on the number of pull requests submitted to the official ROS GitHub repositories, verified by the ROS Discourse community. Currently, there are 535 Contributors, 126 Great Contributors, and only 20 Amazing Contributors worldwide.
ROS is a robotic software development platform that holds significant meaning for me. Since my first encounter with ROS 1 Diamondback in 2011, I have consistently utilized ROS in research and development projects for over 15 years. My Master’s and Ph.D. studies centered around ROS, and it remains an essential development tool at ROBOTIS, where I am currently employed. Additionally, I have attended ROSCon nine times between 2014 and 2022, including presenting at ROSCon 2016.
Moreover, in collaboration with Open Robotics, I contributed to developing TurtleBot3, a ROS standard platform robot launched officially in 2017. TurtleBot3 is an official Open Robotics brand, and ROBOTIS contributes part of the TurtleBot3 sales revenue back to Open Robotics. Thus, every TurtleBot3 user is significantly contributing to the growth of the ROS ecosystem.
Furthermore, I have authored nine ROS-related books translated into English, Japanese, Chinese, and Korean, including “Robot Programming with ROS 2” (Korean edition). I served as a ROS Technical Steering Committee (TSC) member from 2018 to 2019, helping guide the community’s future, and have organized approximately 60 ROS-related seminars, actively promoting the open-source community.
During the ROS 1 Kinetic era, I maintained 154 out of the 2,051 official ROS packages. Although I had slowed down in recent years, I resumed actively developing public packages again this year, regularly updating ROS 2 packages and planning further contributions beneficial to the community.
This ‘ROS Amazing Contributor Badge’ has given me an opportunity to reflect on my journey and deepened my passion for the ROS community. I look forward to continuing my contributions to help many individuals positively impact the robotics industry through ROS.
Furthermore, we are continuing active development not only on TurtleBot3, OpenManipulator, DYNAMIXEL, and Delivery Service Robot (GAEMI) but also advancing leader, follower, and humanoid robots utilizing manipulators essential for the era of Physical AI. Please stay tuned for future developments.
Thanks, Open Robotics and ROS Community. I 
ROS.
