RoboCamp 2026
The second Flix RoboCamp event took place in July 2026 in Saint Petersburg. The main goal for the competitors was to build a Flix-based quadcopter and implement autonomous position control using distance sensors and an overhead camera. Several participants were able to implement altitude hold, and two participants implemented stable position hold.
Highlights
The winning project performed an automatic takeoff, stable position hold (2 min+), and navigation to a point selected by the user by clicking on the camera image.
