Mobile Tethering Control for UAV No-Fly Zone Boundaries
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned aerial vehicles (UAVs) tethered using existing systems can cross into no-fly zones when they lose control near the boundary of permissible flight zones, posing safety risks due to their inability to maintain a safe distance from boundaries.
Innovation Solution
An information processing method that determines a first destination for a mobile tethering body based on the position of the UAV, ensuring it remains at least a predetermined distance from the boundary, thereby preventing the UAV from entering no-fly zones, even if it loses control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tether is attached to an unmanned aerial vehicle to limit flight range, then safety is improved by preventing unauthorized flight areas, but the unmanned aerial vehicle may still cross the boundary into no-fly zones when problems occur and crash into the ground
Solution Approach 1:
The mobile tethering body proactively moves to a predetermined distance from the boundary before the UAV can potentially cross it. This preliminary positioning ensures that even if the UAV loses control, the tether length constraint prevents it from reaching the no-fly zone, thereby eliminating the crash risk while maintaining safety.
Solution Approach 2:
The system dynamically adjusts the position of the mobile tethering body based on the UAV's position and the boundary location. By continuously moving the tethering body to maintain the optimal safety distance, the system adapts to changing conditions while ensuring the UAV remains constrained within safe boundaries.
2Productivity
If the mobile tethering body is positioned closer to the boundary to maximize flight area, then productivity is improved by expanding permissible flight zone, but safety is reduced as the UAV may cross into no-fly zones
Solution Approach 1:
The system calculates and positions the mobile tethering body at a predetermined safe distance from the boundary in advance, before any potential boundary crossing scenario occurs. This preliminary positioning maximizes the usable flight area while inherently preventing crashes by ensuring the tether constraint maintains a safety buffer zone.

AI summary
An information processing method includes the following steps performed using a processor: obtaining first region information indicating a first region; obtaining first position information indicating the position of an unmanned aerial vehicle tethered to a mobile tethering body using a tether; determining, using the first region information and the first position information, a first destination which is a destination of the mobile tethering body; and moving the mobile tethering body to the first destination. The first destination is a position located at least a predetermined distance from a point which is on the boundary of the first region and located the shortest distance from the position of the unmanned aerial vehicle, in the direction from the point on the boundary of the first region to the position of the unmanned aerial vehicle.
