UAV Diagonal Flight Control on Sloped Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing unmanned aerial vehicle (UAV) control systems face difficulties in assisting operators to move the vehicles diagonally, particularly on sloping surfaces like roads or stairs, requiring complex and training-intensive operations.
Innovation Solution
An information processing device that calculates and adjusts movement amounts based on the ratio of horizontal and vertical distances to a surface, allowing the UAV to move diagonally by simultaneously controlling horizontal and vertical movements, assisted by sensors and a decision unit that adjusts movement based on operator input and surface topography.

1Ease of operation
If conventional two-stick control is used for UAV operation, then basic flight control is achieved, but diagonal movement operation becomes difficult and requires extensive training
Solution Approach 1:
The control device introduces a conversion unit as an intermediary between the operator's simple diagonal direction input and the UAV's complex horizontal and vertical movement commands. This conversion unit automatically calculates and converts the single diagonal direction and magnitude input into appropriate horizontal and vertical movement amounts, eliminating the need for operators to manually coordinate multiple stick movements while maintaining precise control.
Solution Approach 2:
The system changes the control parameter from separate horizontal and vertical movement commands to a unified diagonal direction and magnitude parameter. By detecting the diagonal direction via sensors and accepting magnitude input through a simple interface, the system then converts this unified parameter into the necessary horizontal and vertical movement commands, simplifying the operator's task while achieving the desired complex motion.
2Ease of operation
If automatic movement amount adjustment is implemented, then ease of operation improves, but device complexity increases
Solution Approach 1:
The control device performs self-service by automatically detecting the diagonal direction using sensors and autonomously calculating the appropriate horizontal and vertical movement amounts based on the detected direction and operator input magnitude. This self-service capability eliminates the need for complex manual coordination by the operator while keeping the overall system relatively simple through automated conversion rather than adding multiple complex control mechanisms.

AI summary
A controller (2) 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 (1) 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 (1) is to be moved simultaneously in both the horizontal direction and the vertical direction, and moves the unmanned aerial vehicle (1) based on the movement amount.
