Given that AUVSI Xponential is by far the largest drone trade show, I assume quite a few people here will attend this year. The Ardupilot guys will have quite a large booth. Maybe we could organize a meetup of PX4 users and developers? I suggest a lunch on the last day when things are less busy.
RCbenchmark will be attending. If everything goes according to plan, we will have a PX4 based quadcopter flying in a small netted area with our motion capture tool the Otus tracker. We are eventually planning to offer a kit for research and education that is already setup to work out of the box with motion capture and Dronekit. We hope it will help researchers to cut their development time by a few months. We will also demo our thrust and torque measurement tools.
