Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport robots require complex and esoteric instructions, consuming control device resources and making system management difficult for factory and warehouse managers and workers.
Innovation Solution
A transport system and robot using a tree structure address format for instructions, allowing the transport robot to follow a predetermined loading priority order based on inventory information, reducing the need for detailed control device instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If detailed instructions for all robot arm operations are given from the control device, then the transport robot can execute precise loading and unloading operations, but the control device consumes excessive resources and the instruction system becomes complex
Solution Approach 1:
The patent segments the control system into two parts: the control device provides high-level transport instructions (what to transport and where), while the transport robot autonomously generates detailed robot arm control instructions (how to load/unload). This segmentation reduces control device resource consumption and simplifies the instruction system while maintaining precise loading operations through the robot's autonomous control program selection based on inventory information.
2Manufacturing precision
If detailed instructions for all robot arm operations are given from the control device, then the transport robot can execute precise loading and unloading operations, but control device resources are consumed excessively
Solution Approach 1:
The transport robot performs self-service by autonomously generating its own robot arm control instructions based on inventory information stored in its database. The robot selects appropriate control programs from its recording unit without requiring the control device to provide detailed operation instructions, thereby significantly reducing control device resource consumption while maintaining precise loading and unloading operations.
3Extent of automation
If esoteric detailed instructions are used for transport operations, then precise control is achieved, but system management becomes difficult for factory and warehouse managers and workers
Solution Approach 1:
The patent uses a tree structure address format that mirrors the physical layout and organizational hierarchy of the factory or warehouse. This address copying approach makes instructions intuitive and easy to understand for managers and workers, as they directly reflect the actual facility structure. Meanwhile, the transport robot maintains high automation by autonomously interpreting these simple addresses and generating the complex control instructions needed for precise operations.

AI summary
The present invention makes an instruction for causing a transport robot to carry out transport easier for a person to understand. A transport system (1) is such that an address indicating a transport destination or a transport source is represented by a tree structure including a node indicating loading locations and a node indicating equipment to which the loading locations are provided, and when the address of the transport destination indicates equipment, a transport robot (20) sequentially loads objects to be transported in accordance with a preset loading priority order in loading locations where no objects to be transported have been loaded, from among the loading locations belonging to that equipment.
