ROSCon 2023, our twelfth annual ROS developers' conference, was held in New Orleans, Louisiana on October 18-20, 2023. The conference was a success, bringing together over 700 ROS developers from 42 countries to learn from each other and share the latest advances in ROS and robotics technology. We were also thrilled to see the Dronecode Foundation’s flagship PX4 Developers’ Summit hosted immediately after ROSCon in the same venue, allowing a number of attendees to attend both events and learn from others in a closely-related field (not to mention see a fantastic drone show put on by the Dronecode Foundation and UVify!).
