AI Technical Summary
Technical Problem
Unexploded landmines pose a significant safety hazard in areas with dense grass growth, hindering detection and delaying removal due to the risk of detonation and reduced accuracy, making traditional weeding methods dangerous and inefficient.
Method used
An unmanned aerial vehicle (UAV) equipped with rotating blades and sensors is used to cut grass in stages from higher to lower altitudes, avoiding ground contact and entanglement, while incorporating obstacle detection and altitude control to ensure safety and precision.
Benefits of technology
The method enhances the safety and workability of weeding operations by minimizing ground contact and entanglement risks, allowing for consistent quality weeding regardless of operator skill, and improving detection accuracy.

Abstract
Applying unmanned aerial vehicle technology to weed control operations will improve safety and efficiency. [Solution] A weeding method is provided, which includes a weeding step in which an unmanned aerial vehicle equipped with multiple rotors, a cutter unit that cuts grass with rotating blades, and a ground altitude sensor repeatedly moves along a predetermined flight path while gradually lowering its ground altitude while rotating the blades. The problem is solved by an unmanned aerial vehicle equipped with multiple rotors, a control unit that controls the operation of each rotor, a cutter unit that cuts grass with rotating blades, and a ground altitude sensor, wherein when the aircraft is manually controlled, the control unit restricts the operation of each rotor so that the aircraft's ground altitude does not fall below a predetermined height.
