Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UAVs face challenges in providing intuitive, simple, and reliable controllability for semi-autonomous inspection and surveying tasks, particularly in complex environments, due to the complexity of control systems and the need for precise navigation and obstacle avoidance.
Innovation Solution
A UAV system with a directional distance measuring module, such as a lidar, and a touch-sensitive interface on a mobile control device allows for intuitive control through touch inputs, enabling semi-autonomous navigation and inspection by maintaining a constant distance from object surfaces and aligning the main view direction, using touch inputs like strokes and pinches to guide movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a control system with environment sensor system and motion generation system is used to enable semi-autonomous inspection and surveying, then the functionality and automation level of the UAV is improved, but the device complexity and difficulty of control increases
Solution Approach 1:
The UAV autonomously performs inspection and surveying tasks by automatically processing sensor data and generating control commands without continuous human intervention. The system serves itself by independently navigating, detecting obstacles, and capturing environmental data while maintaining semi-autonomous operation capability.
Solution Approach 2:
The control system integrates multiple functions including environment sensing, obstacle detection, autonomous navigation, and inspection/surveying operations into a single unified platform. This multi-functional approach enables the UAV to perform diverse tasks such as building inspection, terrain surveying, and real-time mapping without requiring separate specialized systems.
2Reliability
If a control system with environment sensor system is used to enable obstacle detection and avoidance, then the safety and reliability of the UAV is improved, but the device complexity increases
Solution Approach 1:
The environment sensor system continuously monitors the UAV's surroundings and provides real-time feedback to the motion generation system. This feedback loop enables dynamic obstacle detection and avoidance by comparing current sensor readings with previously mapped environments, allowing the UAV to adjust its trajectory automatically when potential obstacles are detected.
Solution Approach 2:
The system performs preliminary mapping of the environment during initial flight phases, creating a reference model of the inspection area. This pre-established environmental model serves as a baseline for subsequent obstacle detection, enabling the UAV to identify unexpected obstacles more efficiently and respond proactively before collisions occur.
