UAV Diagonal Flight Control Along Sloping Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing unmanned aerial vehicle (UAV) control systems find it difficult for operators, especially beginners, to navigate UAVs in diagonal directions, particularly on sloping surfaces like roads or stairs, due to the complexity of coordinating horizontal and vertical movements.
Innovation Solution
An information processing device that calculates and adjusts movement amounts based on the ratio of horizontal to vertical distances from the UAV to the surface, using sensors to measure these distances and adjust the UAV's movement accordingly, allowing for easier diagonal navigation.

Engineering Contradiction Analysis
1Ease of operation
If conventional two-stick control is used for UAV operation, then basic flight control is achieved, but diagonal movement control becomes difficult and requires extensive training
Solution Approach 1:
The control device introduces an intermediary calculation mechanism that automatically computes the relationship between stick displacement amounts and UAV movement amounts. This intermediary processing layer translates simple stick inputs into appropriate diagonal movement commands, eliminating the need for operators to manually coordinate complex horizontal and vertical movements.
Solution Approach 2:
The system dynamically changes the movement amount parameters based on the ratio between horizontal and vertical distances to the sloping surface. By adjusting the movement amount in response to distance ratio changes, the system adapts to different diagonal angles and slopes, making control easier across various terrain conditions.
2Measurement precision
If manual coordination of horizontal and vertical movements is required, then precise control is possible, but operation difficulty increases significantly for beginners
Solution Approach 1:
The control device performs self-service by automatically calculating and adjusting movement amounts based on measured distance ratios. The system independently determines the appropriate horizontal and vertical movement components without requiring operator intervention, thereby maintaining precision while reducing operational difficulty.
Solution Approach 2:
The system implements feedback by continuously measuring distances to the sloping surface and using this information to adjust movement amounts. The calculation unit receives feedback from distance measurements and automatically modifies control outputs to maintain accurate diagonal movement along the slope.
3Ease of operation
If automatic movement adjustment is implemented, then diagonal navigation becomes easier, but system complexity increases
Solution Approach 1:
The control device achieves multi-functionality by integrating distance measurement, ratio calculation, and movement amount adjustment within a single unified system. This universal approach handles various diagonal navigation scenarios (different slopes, angles, and distances) using the same core mechanism, avoiding the need for separate complex subsystems.

AI summary
A controller obtains a first horizontal distance and a first vertical distance which are respectively a component in a horizontal direction and a component in a vertical direction among distances from an unmanned aerial vehicle to a surface of a particular place where elevation gradually increases or decreases along the horizontal direction, decides, based on a ratio of the first horizontal distance to the first vertical distance, a movement amount by which the unmanned aerial vehicle is to be moved simultaneously in both the horizontal direction and the vertical direction, and moves the unmanned aerial vehicle based on the movement amount.
