Cargo Container Butting Using Marker-Guided Robot Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the warehousing industry, robots face inefficiencies when moving cargo containers due to placement precision issues, leading to longer times and reduced efficiency in butting and moving containers, as the actual placement position often deviates from the predetermined coordinate position.
Innovation Solution
A method and apparatus where a robot adjusts its travel direction based on the position of markers on the cargo container to accurately reach the butting position, utilizing sensors and marker identification modules to determine the practical placement position and angle, allowing precise butting and movement of the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a positioning auxiliary mark is attached on the cargo container and the robot searches back and forth around the mark to achieve precise butting, then the positioning precision is improved, but the butting time increases and efficiency decreases
Solution Approach 1:
The patent applies preliminary action by pre-calculating the reference position of the cargo container based on the position of the positioning auxiliary mark before the robot begins its butting operation. This allows the robot to directly navigate to the calculated position without performing time-consuming back-and-forth searching, thereby achieving both high positioning precision and reduced butting time
Solution Approach 2:
The patent uses feedback by continuously monitoring the position of the positioning auxiliary mark on the cargo container and adjusting the robot's travel direction accordingly. The system calculates the deviation from the predetermined position and dynamically adjusts the reference position to ensure accurate butting while minimizing search time
2Measurement precision
If the robot uses the predetermined position and positioning auxiliary mark to search for the cargo container, then the positioning accuracy is improved, but the operational efficiency decreases due to back-and-forth searching
Solution Approach 1:
The system performs preliminary calculation of the reference position based on the positioning auxiliary mark before the robot executes the butting operation. This pre-computation eliminates the need for time-consuming search operations while maintaining high positioning accuracy
Solution Approach 2:
The patent implements dynamic adjustment of the reference position based on the actual position of the cargo container. The system continuously updates the travel direction and reference position in real-time, allowing the robot to adapt to position deviations without performing static back-and-forth searches, thereby improving operational efficiency
