UAV Obstacle Feedback Control During Automatic Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current UAV systems lack effective obstacle notification methods, leading to user confusion when obstacle avoidance operations are triggered, as operation commands may be blocked, and the lack of clear notifications can result in misconceptions about UAV malfunctions.
Innovation Solution
A method and device for controlling UAVs that involve obtaining depth data of obstacles using sensors, determining information about obstacles that trigger avoidance operations, and transmitting this information to a control terminal for real-time mapping onto interactive devices, allowing users to understand the UAV's current state and operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the smart control system controls the UAV to execute obstacle avoidance operation, then the safety of the UAV and ground objects is ensured, but the operation commands input by the user are blocked and the user cannot understand the current operation state
Solution Approach 1:
The patent implements a feedback mechanism where the smart control system sends notifications to the control terminal when automatically controlling the UAV for obstacle avoidance. The notification includes obstacle information such as type, location, and distance, allowing the user to understand the current operation state while maintaining the safety benefits of automatic obstacle avoidance
Solution Approach 2:
The control terminal acts as an intermediary between the smart control system and the user. It receives obstacle information from the smart control system via the notification module and displays it through the display module, bridging the information gap when the user's direct control is blocked during automatic obstacle avoidance operations
2Reliability
If the smart control system blocks operation commands during obstacle avoidance, then collision is avoided, but the user may have the illusion that the UAV has malfunction or lost control
Solution Approach 1:
The notification module provides real-time feedback to the user by sending obstacle information to the control terminal during automatic obstacle avoidance. This feedback explains why the UAV is executing avoidance maneuvers, preventing user confusion or misconception about system malfunction while maintaining collision avoidance effectiveness
Solution Approach 2:
The display module uses visual indicators such as different colors to represent various obstacle types and states (e.g., red for high-risk obstacles, yellow for medium-risk). This visual coding system makes the obstacle information intuitive and easy to understand, maintaining ease of operation during automatic avoidance maneuvers

AI summary
A method for controlling an unmanned aerial vehicle (“UAV”) includes obtaining depth data of one or more obstacles in a flight space. The method also includes determining information of an obstacle that triggers an obstacle avoidance operation based on the depth data. The method further includes transmitting the information of the obstacle to a control terminal of the UAV.
