Marker-Guided Flight Control Without GPS or Stored 3D Routes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large indoor facilities, preparing and storing a three-dimensional flight route for a flying object is time-consuming and labor-intensive, and requires significant storage capacity, making it inefficient and costly.
Innovation Solution
A control system for a flying object that uses markers with control information, including movement vectors, fail-safe codes, and flight state data, which are read by a control device to autonomously guide the object without pre-storing the entire flight route, allowing for safe and accurate navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a three-dimensional flight route is stored in the control device, then the flying object can be controlled to fly autonomously along the stored flight route, but the amount of information prepared becomes enormous and it takes time and labor to prepare the entire route
Solution Approach 1:
The flight route is segmented into multiple markers positioned at different locations along the route. Each marker contains only the control information necessary for that specific segment, rather than storing the entire route in one place. This segmentation reduces the information preparation burden while enabling autonomous flight through sequential marker recognition.
Solution Approach 2:
The essential control information is extracted from the complete flight route and embedded directly into markers positioned at key locations. Instead of storing and processing the entire route in the control device, only the necessary directional and positional information is extracted and placed in markers, reducing preparation time and computational load.
2Extent of automation
If a three-dimensional flight route is stored in the control device, then autonomous flight along the route is enabled, but a storage device for storing the entire flight route becomes large
Solution Approach 1:
The flight route information is segmented and distributed across multiple markers rather than stored centrally. Each marker contains only the control information relevant to its location, significantly reducing the storage requirements in the control device while maintaining autonomous flight capability through sequential marker reading.
Solution Approach 2:
Instead of storing the complete flight route in the control device, simplified copies of the route information are created in the form of markers positioned at key locations. These markers contain condensed control information that can be read sequentially, reducing storage device size while preserving autonomous navigation functionality.
3Loss of time
If markers with control information are used to guide the flying object, then storage needs are reduced and preparation time is decreased, but the system requires reading units and marker positioning infrastructure
Solution Approach 1:
The mechanical system of storing and processing large amounts of route data in the control device is replaced with an optical/information-based system using markers and reading units. This substitution reduces preparation time and storage requirements, as markers can be quickly positioned and read without complex data processing, though it introduces new system components.

AI summary
Problem: To provide a control system and a control device for a flying object that autonomously flies the flying object without using a GPS and without storing a flight route. Means for solving the problem: A control system 2 for a flying object includes at least one marker 6, which corresponds to control information related to the control of the flying object, a reading unit 12 for reading the control information, and a flight information transmitting unit 14 for transmitting flight information to the flying object based on the control information read by the reading unit.
