Coordinated Drone and Carrier Planning for Safe Field Spraying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current drone systems for agricultural chemical agent application lack a foolproof safety mechanism and efficient operation planning, particularly for autonomous flight, as they do not coordinate the drone's flight plan with the movable body's movement plan, leading to potential accidents and operational inefficiencies.
Innovation Solution
A drone system that includes a plan determining section to coordinate flight and movement plans between the drone and the movable body, allowing for automatic operation planning, relay points, and dynamic adjustments based on battery charge and chemical agent levels, ensuring safe and efficient operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a drone executes predetermined operation by automatic flight without coordinated planning with movable body, then autonomous operation capability is improved, but operational safety deteriorates due to lack of foolproof mechanisms
Solution Approach 1:
The plan determining section continuously monitors the drone's operational status, battery level, and chemical agent remaining amount, dynamically adjusting the flight plan and movable body movement plan based on real-time feedback to ensure safe operation throughout the mission
Solution Approach 2:
The system determines the complete flight plan and movement plan in advance before the drone takes off, including predetermined landing points and relay points, ensuring that all safety-critical decisions are made before autonomous operation begins
2Adaptability or versatility
If flight plan is determined without coordinating movable body movement plan, then flight operation flexibility is improved, but operational efficiency deteriorates due to lack of coordinated scheduling
Solution Approach 1:
The system merges the flight plan determination and movable body movement plan determination into a single integrated process, where both plans are generated simultaneously with coordinated timing and spatial information, ensuring optimal operational efficiency
3Reliability
If takeoff-landing equipment is separate from movable body, then drone operation safety is improved, but operational flexibility deteriorates due to fixed takeoff-landing points
Solution Approach 1:
The movable body is designed to serve dual functions: it transports the drone to various locations and simultaneously acts as the takeoff and landing equipment, eliminating the need for separate fixed infrastructure while maintaining safe operation through coordinated planning
4Ease of operation
If operation plan is not dynamically adjusted based on battery and chemical agent levels, then operational simplicity is improved, but operational efficiency deteriorates due to inability to adapt to changing conditions
Solution Approach 1:
The system dynamically adjusts the flight plan and movement plan based on real-time conditions including battery charge level and chemical agent remaining amount, automatically determining relay points and landing points to optimize operational efficiency without requiring complex manual intervention

AI summary
In a drone system in which a drone and a movable body operate in coordination with each other, the drone performing a predetermined operation in an agricultural field, the movable body being capable of moving with the drone aboard and allowing the drone to make a takeoff and a landing, the plan determining section determines a flight plan for the drone and a movement plan for the movable body in accordance with the flight plan, and the instructing section instructs the drone to execute an operation in accordance with the flight plan and instructs the movable body to move or to be on standby in accordance with the movement plan.
