Drone Landing Coordination With a Moving Takeoff Platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current drone systems lack adequate safety measures for autonomous flight, particularly when used for agricultural chemical agent dispersal, as they do not ensure proper coordination between drones and movable bodies for takeoff and landing, which can lead to accidents.
Innovation Solution
A drone system that includes a movable body capable of transporting the drone, with coordinated communication and control mechanisms allowing the drone to safely take off and land, using a takeoff-landing area, movement control, and information exchange between the drone and movable body to ensure safe operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If autonomous flight control is implemented, then operational efficiency is improved, but safety is worsened due to lack of coordination between drone and movable body
Solution Approach 1:
The patent implements a feedback mechanism where the drone and movable body continuously exchange information about their states, positions, and operational parameters. The flight control section receives information from the movable body transmission section and sends control commands back, creating a closed-loop control system that ensures safe autonomous operation while maintaining coordination between the drone and movable body.
Solution Approach 2:
The patent introduces an information exchange system as an intermediary between the drone and movable body. This intermediary mechanism transmits critical data such as position coordinates, operational status, and control commands, enabling autonomous operation while maintaining safety through coordinated communication without requiring direct mechanical connection or manual intervention.
2Reliability
If coordination mechanisms are added between drone and movable body, then safety is improved, but system complexity is worsened
Solution Approach 1:
The patent designs the information exchange system to serve multiple functions simultaneously: position tracking, coordination control, safety monitoring, and operational management. By making the communication system multi-functional, the patent avoids adding separate dedicated systems for each function, thereby improving safety without proportionally increasing system complexity.
Solution Approach 2:
The patent merges the coordination functions between drone and movable body into a unified control architecture. The flight control section and movable body transmission section are integrated to share information and coordinates, combining multiple safety and coordination functions into a single integrated system rather than separate independent systems, thus improving safety while controlling complexity.
3Measurement precision
If information exchange system is implemented, then coordination accuracy is improved, but communication requirements are worsened
Solution Approach 1:
The patent implements preliminary action by pre-establishing communication protocols and information exchange formats between the drone and movable body before operation begins. The system pre-defines the structure and content of messages to be exchanged, ensuring that all necessary coordination information is communicated accurately without requiring complex real-time negotiation or additional communication overhead during actual operation.

AI summary
There is provided a drone system in which a drone and a movable body operate in coordination with each other, the movable body being capable of moving with the drone aboard and allowing the drone to make a takeoff and a landing, the movable body including: a takeoff-landing area on which the drone can be placed and that serves as a takeoff-landing point from and on which the drone takes off and lands; a movement control section capable of moving the movable body together with the drone aboard; and a movable body transmission section that sends information on the movable body, the drone including: a flight control section that causes the drone to fly; and a drone reception section that receives information on the movable body, wherein the drone sends, to the movable body, a position of a takeoff-landing point at a time when the drone takes off.
