Indoor Drone Navigation With Privacy-Aware Damage Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for unmanned vehicle surveillance within structures lack effective communication and navigation methods to ensure privacy and appropriate access control, particularly in sensitive areas like bedrooms or bathrooms, and struggle to provide real-time feedback on mission progress and damage assessment.
Innovation Solution
The system employs an unmanned vehicle equipped with sensors, a data analysis engine, route determination engine, and sensor management engine, which communicates with a network and server to generate and update maps, navigate through structures, and provide feedback through graphic representations like heat maps, while implementing virtual knocks for access control and sensor deactivation based on user presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the unmanned vehicle continuously surveys and maps the entire structure, then the completeness of surveillance data is improved, but the time required to complete the mission and the energy consumption increase
Solution Approach 1:
The system performs partial surveillance by identifying and focusing only on areas requiring assessment rather than continuously surveying the entire structure. The unmanned vehicle uses sensors to detect changes from baseline data and selectively surveys only those areas where damage or changes are detected, rather than uniformly scanning all areas.
Solution Approach 2:
Baseline data is collected and stored before the actual surveillance mission. This preliminary action creates a reference framework that allows the unmanned vehicle to quickly identify areas of change during the mission, eliminating the need to survey every area from scratch and significantly reducing mission time.
2Loss of information
If the unmanned vehicle enters sensitive areas like bedrooms or bathrooms for surveillance, then the completeness of damage assessment is improved, but privacy concerns and access control issues arise
Solution Approach 1:
The system applies different surveillance rules and sensor activation patterns to different areas of the structure. Sensitive areas like bedrooms and bathrooms have specific access protocols, virtual knock requirements, and sensor deactivation rules that differ from non-sensitive areas, allowing appropriate privacy protection while still enabling damage assessment where needed.
Solution Approach 2:
A virtual knock mechanism serves as an intermediary between the unmanned vehicle and occupants of sensitive areas. The system notifies occupants of approaching surveillance in private spaces, allowing them to prepare or restrict access, thus mediating between the need for complete damage assessment and the need for privacy protection.
3Measurement precision
If multiple sensors are deployed on the unmanned vehicle to gather comprehensive data, then the accuracy of damage assessment is improved, but the device complexity and cost increase
Solution Approach 1:
The sensor system is dynamic and adaptive rather than static. Sensors are selectively activated and deactivated based on the current mission phase, location, and detected conditions. The sensor management engine adjusts which sensors are active at any given time, reducing overall system complexity while maintaining high measurement precision when needed.
Solution Approach 2:
The unmanned vehicle is designed with multi-functional sensors that can perform multiple detection tasks. A single sensor system can detect structural damage, map environments, identify changes from baseline data, and assess various types of conditions, reducing the total number of specialized sensors needed while maintaining comprehensive assessment capability.

AI summary
Unmanned vehicles can be terrestrial, aerial, nautical, or multi-mode. Unmanned vehicles may be used to survey a property in response to or in anticipation of a security threat or damage to the property. For example, an unmanned vehicle may analyze information about the property and based on the information provide graphics and information associated with the surveying of the property.
