Remote Controlled Boat Autonomous Navigation via Dual GPS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote-controlled unmanned vessels lack advanced navigation capabilities, as they often rely solely on onboard global positioning systems without communication with a remote controller, limiting their ability to autonomously navigate to the controller's location.
Innovation Solution
Incorporating both a global positioning system and a communication unit into the remote controller and the unmanned vessel, allowing for remote communication and coordination between the two, enabling various modes of operation such as remote control, stay here, and come to me modes, with features like handles, sensors, cameras, and propulsion units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a global positioning system is installed only on the unmanned vessel, then the vessel can be remotely controlled, but the vessel cannot autonomously navigate to the controller's location
Solution Approach 1:
The patent merges the global positioning system functionality into both the unmanned vessel and the remote controller. The vessel includes a first global positioning unit to determine its own location, while the controller includes a second global positioning unit to determine the controller's location. This combination enables the vessel to autonomously navigate to the controller by comparing location data from both units, resolving the limitation of not having controller location information.
2Adaptability or versatility
If autonomous navigation features are added to the unmanned vessel, then navigation versatility is improved, but the device complexity increases
Solution Approach 1:
The patent implements multi-functionality by enabling the same hardware components (global positioning units, communication units, and central processing units) to support multiple navigation modes. The system can switch between remote control mode, stay here mode, and come to me mode using the same underlying hardware, thereby achieving navigation versatility without proportionally increasing device complexity.
Solution Approach 2:
The navigation system is segmented into distinct operational modes (remote control mode, stay here mode, come to me mode) that can be independently activated. Each mode utilizes the same hardware components but applies different control logic, allowing the system to provide diverse navigation capabilities while maintaining a relatively simple unified hardware architecture.
3Measurement precision
If real-time communication between controller and vessel is implemented, then navigation accuracy is improved, but energy consumption increases
Solution Approach 1:
The communication system implements periodic data transmission rather than continuous communication. The vessel's central processing unit determines navigation commands based on received controller commands and current location data, then transmits execution results periodically. This periodic action maintains real-time navigation accuracy while significantly reducing energy consumption compared to continuous communication.
