Design Process
Our UAV platform is built on the Holybro X650 Dev Kit , fitted with RTK-GNSS for centimeter-level navigation and powered by a Tattu 8000 mAh LiPo battery for extended endurance.
-
Requirements & Research: Identified payload, endurance, and environmental constraints alongside agronomy experts.
-
Concept & CAD Modeling: Sketched layouts and built detailed Fusion 360 assemblies, optimizing center-of-gravity and rigidity.
-
Holybro H-RTK F9P GNSS Integration: Installed and configured the RTK base/rover pair for centimeter-level positioning.
-
Iterative Prototyping: Bench-tested wiring, firmware, and mounts on the X650 frame, then refined through field trials.

Pre-flight
Frame Construction
Mounted the Holybro X650 arms to the carbon-fiber center plate, torquing all screws to spec and verifying structural rigidity.
Electronics Stack
Installed Pixhawk controller, ESCs, PDB, and neatly routed wiring for clean signal paths and easy maintenance.
Sensor Integration
Secured the RTK-GPS module, LiDAR height sensor, and Jetson Nano bracket to enable precision navigation and onboard vision.
Power Systems
Connected the Tattu 8000 mAh LiPo battery via XT60 harness, balanced leads, and calibrated the battery monitor.
Pre-flight Checks
Ran motor spin-up tests, completed compass and accelerometer calibration, and verified all fail-safe settings before lift-off.
Test Flight
🏁 First Hover
Checked hover stability at 3 meters above ground, ensuring ±0.2 m altitude hold before moving on.
🛣️ Coverage Path
Executed a 10-waypoint square pattern—verified GPS track versus planned route with 1.5 % max deviation.
🔊 Deterrence Test
Triggered audio repellents over simulated deer targets; measured reaction distance and response time.
