 Dear AtsushiSakai, <br>thank you for building this cool repo for robotics. <br>I am still learning robotics and this will give me a good starting point. <br>I hope this note gets to you. <br> <br>

 Dear AtsushiSakai, <br>WE found your project from google when first searching for a rosbag to csv converter. We are a small team in MCity working on Connected (and Automated) vehicles. We are working with an opensource platform that serve as the AI to control the vehicle. Your code and documentation helped us a lot! <br> <br>Thank you! Have a nice day!
