Shelf Handling Robot Alignment Using Mark-Point Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional manual sorting methods in the express delivery industry face challenges such as high error rates, labor intensity, low space utilization, and management difficulties, leading to inefficiencies in logistics handling, particularly when shelves need to be accurately placed at preset coordinates.
Innovation Solution
A handling method and system that involves a handling device with a walking mechanism, docking head, lifting mechanism, target identification assembly, and control module, which advances at different speeds to accurately identify and align with shelves, reducing the need for repeated searches and enhancing efficiency by moving directly to the preset position after alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the logistics robot stops to search for the shelf after arriving at the coordinate position but fails to identify it, then the shelf can be located, but the operating time of the logistics robot is prolonged
Solution Approach 1:
The patent applies preliminary action by having the logistics robot slow down before reaching the preset coordinate position and start identifying the shelf in advance, rather than stopping completely to search. This preparatory identification process ensures the shelf is located while minimizing time loss, as the robot maintains forward motion at a reduced speed during identification.
2Productivity
If the logistics robot advances at high speed to the coordinate position, then efficiency is improved, but the ability to accurately identify and align with the shelf is reduced
Solution Approach 1:
The patent applies dynamics by changing the robot's speed dynamically based on its distance from the target shelf. The robot advances at a first (higher) speed when far from the shelf to maintain efficiency, then automatically slows down to a second (lower) speed when approaching the preset coordinate position to enable accurate identification and alignment. This dynamic speed adjustment optimizes both productivity and measurement precision.
3Reliability
If the logistics robot repeatedly stops and searches for the shelf, then the shelf can be found, but the handling efficiency is reduced
Solution Approach 1:
The patent applies continuity of useful action by eliminating repeated stopping and searching. The robot continuously moves forward toward the shelf while maintaining identification capability through continuous movement at the second speed. This continuous action ensures the shelf is located through ongoing identification rather than intermittent searching, thereby maintaining both reliability and productivity.

AI summary
Disclosed are a handling method, a handling device, and a handling system. The handling method includes: advancing toward a position of the target object at a first speed according to a navigation route; advancing toward the position of the target object at a second speed in response to the distance between a current position of the handling device and the position of the target object becoming less than or equal to a first distance, the second speed being less than the first speed; identifying a mark point on the target object when advancing at the second speed, and aligning with the target object according to the mark point of the target object in response to having identified the mark point on the target object; stopping advancing and lifting up the target object after aligning with the target object; and advancing toward a preset position after lifting up the target object.
