Pallet Stocker Coordinate Teaching for Automated Robot Gripping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport systems require significant labor for robot teaching operations, which is inefficient and time-consuming.
Innovation Solution
A transport system and automatic teaching method that includes a pallet stocker with a shelf plate, a robot with a hand to grip pallets, and a robot control unit that detects and generates a user coordinate system based on specific portions of the pallet stocker, reducing the need for manual teaching by automating the detection and calculation of grip positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual teaching operation is used to teach robot movement, then the robot can be controlled to transport pallets, but the labor required for teaching operation is significant and time-consuming
Solution Approach 1:
The system enables automatic teaching where the robot autonomously detects positions of three portions of the pallet stocker and calculates grip portion positions using coordinate system generation, eliminating the need for manual teaching operations and significantly reducing teaching time
Solution Approach 2:
The patent replaces manual mechanical teaching operations with an automated detection and calculation system that uses coordinate geometry and positional relationships to determine robot movement parameters, substituting human labor with computational processes
2Extent of automation
If automatic teaching method is implemented using coordinate system generation, then labor required for teaching operation is reduced, but the system complexity increases due to detection and calculation processes
Solution Approach 1:
The patent introduces a robot control unit as an intermediary that bridges the detection of physical positions and the calculation of grip portion coordinates, managing the complex automated teaching process through structured control logic and coordinate system transformations

AI summary
A transport system includes a robot control unit. The robot control unit operates a robot to detect positions of three portions of a pallet stocker distant from one another and generates a user coordinate system in the pallet stocker based on the detected positions. The robot control unit operates the robot to detect a position of a specific portion of a shelf plate and calculates a position of a grip portion of the pallet in the user coordinate system based on the detected position and a positional relationship between the specific portion and the grip portion with the pallet being placed on the shelf plate.
