Drone and Movable Body Coordination for Safe Autonomous Takeoff
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of safety technologies specifically designed for autonomous drones used in agricultural chemical spraying, particularly in ensuring safe take-off, flight, and landing operations, and coordinating these processes with a movable body that transports the drone.
Innovation Solution
A drone system that includes a movable body capable of loading and unloading the drone, with a flight controller and communication systems to manage flight operations, restrict movable body movements during flight, and indicate flight status, ensuring safe autonomous flight and landing procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the movable body moves during drone flight, then transportation efficiency is improved, but safety is compromised
Solution Approach 1:
The movable body dynamically adjusts its operational state based on real-time communication with the drone. The system transitions between movable and immovable states, and between different operational modes, to optimize both transportation efficiency and flight safety. This dynamic adaptation resolves the contradiction by making the system flexible rather than fixed.
Solution Approach 2:
The system implements continuous feedback through communication between the drone's flight controller and the movable body's controller. The drone transmits flight status information, and the movable body receives and processes this data to determine whether to move or remain stationary. This feedback loop ensures safety while maintaining operational efficiency.
2Reliability
If the movable body restricts movement during flight, then safety is improved, but operational flexibility deteriorates
Solution Approach 1:
The movable body employs dynamic mode switching between movable and immovable states based on real-time flight conditions. This dynamic behavior allows the system to be restrictive when safety is paramount while remaining flexible when operational needs arise, resolving the contradiction between safety and operational flexibility.
Solution Approach 2:
The movable body autonomously determines its operational state by receiving flight status information from the drone and independently deciding whether to move or remain stationary. This self-service capability eliminates the need for constant external control, maintaining both safety and operational flexibility.
3Reliability
If the system implements comprehensive safety monitoring, then safety is improved, but system complexity increases
Solution Approach 1:
The safety monitoring system uses straightforward feedback mechanisms where the drone transmits flight status information to the movable body, which then adjusts its operational state accordingly. This feedback-based approach provides comprehensive safety monitoring without requiring complex coordination systems, as each component independently processes information and acts autonomously.

AI summary
A drone system that includes a drone and a movable body which is movable with loading the drone and where the drone can take off and land, cooperate to operate and that is able to maintain a high level of safety even during autonomous flight, is provided. The drone has a flight controller controlling a flight of the drone, and a drone transmitter transmitting an information possible to distinguish whether the drone is in flight. The movable body has a take-off and landing area where the drone is loaded, takes off and lands, a movement controller loading the drone on the take-off and landing area and moving the movable body with the drone, a movable body receiver receiving an information from the drone, and a display unit.
