Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal drones require dedicated wireless remote control devices, necessitating skill and practice for operation and are not usable without them, making them cumbersome for single-person use.
Innovation Solution
The development of voice-controlled drone systems that allow users to issue voice commands for functions like altitude control, camera operations, and movement, enabling autonomous flight and image capture, with onboard and offboard microphones for voice recognition and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated wireless remote control device is used to control the drone, then the drone can be operated with precise control, but the operation becomes complex and requires skill and practice
Solution Approach 1:
The patent replaces the mechanical remote control system with an acoustic control system. The drone uses onboard microphones to capture voice commands and processes them through speech recognition algorithms, substituting the mechanical controller with an acoustic field-based control mechanism. This eliminates the need for physical remote control devices and reduces operational complexity while maintaining control precision.
2Adaptability or versatility
If a dedicated wireless remote control device is required for drone operation, then control functions can be implemented, but the system becomes cumbersome and requires carrying multiple devices
Solution Approach 1:
The patent merges the control device and the drone into a single integrated system. The voice recognition processor and microphones are incorporated directly into the drone, eliminating the need for separate remote control devices. This consolidation reduces system complexity and improves portability while maintaining full control functionality.
Solution Approach 2:
The drone's onboard processing unit serves multiple functions: it controls flight operations, processes voice commands, recognizes speech patterns, and executes control functions. This multi-functionality eliminates the need for dedicated remote control devices, as the drone can independently process and respond to voice commands while maintaining full operational capability.
3Ease of operation
If voice control is implemented without remote control device, then portability and ease of operation are improved, but voice recognition accuracy must be maintained in noisy environments
Solution Approach 1:
The patent implements feedback mechanisms where the drone continuously monitors audio input, processes voice commands through speech recognition algorithms, and adjusts its response based on recognition confidence levels. The system can request clarification or filter out background noise dynamically, maintaining high accuracy even in noisy environments while preserving the simplicity of voice-based operation.
Data Source
AI summary
A drone system is configured to capture an audio stream that includes voice commands from an operator, to process the audio stream for identification of the voice commands, and to perform operations based on the identified voice commands. The drone system can identify a particular voice stream in the audio stream as an operator voice, and perform the command recognition with respect to the operator voice to the exclusion of other voice streams present in the audio stream. The drone can include a directional camera that is automatically and continuously focused on the operator to capture a video stream usable in disambiguation of different voice streams captured by the drone.
