Flying Harvester Control Using Collection Vehicle Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flying objects perform work at unintended locations, leading to inefficiencies and potential damage due to high-speed collisions with collection vehicles.
Innovation Solution
A work system comprising a flying object with a harvester, a collection vehicle, and control mechanisms using GPS positioning and range setters to ensure work is performed only at intended locations, with a delivery section to reduce impact and collision risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the flying object performs work automatically based on captured images and neural network detection, then labor required for harvesting work is reduced, but work may be performed at locations unintended by the user
Solution Approach 1:
The system implements feedback control by continuously monitoring the collection vehicle's position via GPS and using this information to adjust and control the flying object's work operations. The work controller receives position information from the collection vehicle and uses it to determine whether to perform work, creating a closed-loop control system that prevents work at unintended locations.
Solution Approach 2:
The collection vehicle position information acts as an intermediary that mediates between the automated detection system and the work execution. Instead of relying solely on image-based automated detection, the system introduces position information as an intermediate control parameter that must be satisfied before work is performed, ensuring location accuracy.
2Productivity
If the flying object delivers work-related items to the collection vehicle at high speed, then delivery efficiency is improved, but collision damage increases
Solution Approach 1:
The system applies beforehand cushioning by reducing the falling speed of work-related items before they reach the collection vehicle. The delivery section includes mechanisms that slow down items during delivery, cushioning the impact before contact with the collection vehicle to prevent damage while maintaining delivery functionality.
3Ease of operation
If the flying object operates without position control, then operational flexibility is maintained, but work is performed at unintended locations
Solution Approach 1:
The system implements dynamic position control where the work range is not fixed but dynamically adjusted based on the collection vehicle's real-time position. The work controller continuously updates the acceptable work area as the collection vehicle moves, maintaining operational flexibility while ensuring work location precision through adaptive control boundaries.

AI summary
A work system includes a flying object including a body capable of flight and a work section to perform work, a collection vehicle to collect a work-related item related to body work that is work performed by the body, a collection vehicle position acquirer configured or programmed to acquire collection vehicle position information indicating a position of the collection vehicle, and a work controller configured or programmed to control the body work based on the collection vehicle position information.
