Perception

Vision and LiDAR, fused on board

360° LiDARForward, upward and downward sensingOnboard fusion

Omnidirectional LiDAR

360°· 15 m radius

Obstacle detection all the way around the aircraft.

Forward vision

120°FOV

Wide-angle forward obstacle sensing.

Upward LiDAR

500Hz · 0.2–20 m

Overhead ranging in flight; 40 m clearance scan before take-off.

Downward LiDAR

mmlevel AGL

Height above ground for precision landing and terrain following.

Sensor fusion

The YOLO vision model identifies what an object is; 2D LiDAR measures how far away it is. Both are fused on the edge computer for real-time avoidance.

Also on board

Upward wide-angle vision camera, and temperature and humidity sensors that feed the take-off weather checks.

Rings every 5 m. The forward field shows angle only; a range for the forward vision sensor is not published.

Elevation

System architecture

Data flow on the aircraft and to the ground segment

VAJRON AI Inspection Drone system architecture On the aircraft, perception sensors and the gimbal camera feed an onboard NVIDIA Jetson edge computer, which provides obstacle data to flight control and sends results to the communications link. RTK GNSS navigation, corrected by a ground base station, feeds flight control. The 4G link serves the mobile application and the ground control station. A protected battery tray with battery management supplies all subsystems.
