Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If human pilots manually control the drone, then the drone can navigate courses, but the speed and agility are limited
Solution Approach 1:
The patent replaces the mechanical manual control system with an AI-based autonomous navigation system. The AI controller processes visual data from cameras and sensor data from IMUs to automatically determine flight paths and control drone movements, eliminating the need for manual pilot input and enabling higher speeds and agility through intelligent decision-making algorithms.
Solution Approach 2:
The drone system performs self-navigation by autonomously processing sensor data and determining its own flight paths. The AI controller independently analyzes camera feeds, processes IMU data, and controls the drone's movements without external human intervention, allowing the system to self-optimize its navigation for maximum speed and agility.
2Extent of automation
If multiple cameras and sensors are added for AI navigation, then autonomous flight capability is improved, but device complexity increases
Solution Approach 1:
The patent employs a multi-functional sensor system where cameras serve dual purposes: capturing visual data for AI navigation and providing first-person view footage for remote monitoring. The IMU sensors simultaneously provide orientation data for autonomous flight control and calibration information for the AI algorithms, reducing the need for separate dedicated components.
Solution Approach 2:
The patent merges the navigation and monitoring functions into a single integrated system. The same camera array used for autonomous navigation also provides visual feedback for the flight controller, and the IMU data serves both autonomous path planning and real-time drone state monitoring, thereby reducing overall system complexity despite having multiple sensors.
3Measurement precision
If AI controller processes real-time camera and sensor data, then flight path determination is improved, but processing time and computational load increase
Solution Approach 1:
The patent performs preliminary processing of sensor data by continuously calibrating the IMU sensors and pre-processing camera feeds to identify key features and establish reference frames. This preliminary action reduces the computational burden during real-time flight path determination, allowing the AI controller to quickly process new data without significant delays.
Solution Approach 2:
The system implements feedback mechanisms where the AI controller continuously adjusts its processing based on real-time performance. If processing time exceeds thresholds, the system dynamically adjusts the level of processing detail, prioritizing critical navigation data over less critical analysis, thereby maintaining accurate flight path determination while reducing unnecessary processing delays.
Data Source
AI summary
A method of simulating a quadcopter includes recording camera output for one or more video cameras under constant conditions and subtracting a constant signal from the recorded camera output to obtain a camera noise recording. Simulated camera noise is generated from the camera noise recording and is added to a plurality of simulated camera outputs of a quadcopter simulator to generate noise-added simulated camera outputs. The noise-added simulated camera outputs are sent to an Artificial Intelligence (AI) controller coupled to the quadcopter simulator for the AI controller to use to pilot a simulated quadcopter of the quadcopter simulator.
