Hello again to all university students, graduate students, and researchers dedicating yourselves to the study of aerospace engineering and autonomous drones! Through [Series 1] and [Series 2], we eliminated mechanical play in our hardware, minimized control latency, and successfully completed “Filter Tuning” by analyzing flight logs to block out vibrations. Now, your drone is in…
Hello, this is QUAD Drone Laboratory.I’m Geunchan Lee, Senior Researcher at QUAD Drone Lab. In the previous post, I introduced the propulsion system selection process for the 911 FALCON drone. Using the mission requirements as fixed KPIs, I explained how the frame and propeller class, target AUW, motor, ESC, and battery were progressively refined through…
