Transport Robot Retrieval Control Using 3D Goods Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport robots in intelligent storage systems require tedious labeling processes, such as attaching two-dimensional codes or RFID tags, to identify and retrieve goods, which decreases operational efficiency.
Innovation Solution
A control method for transport robots that utilizes three-dimensional imaging and status information of target goods to accurately determine their position and posture, eliminating the need for pre-labeling by adjusting the carrying apparatus's position and posture accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transport robots use labeling processes (two-dimensional codes, RFID tags) to identify goods, then goods can be accurately identified and retrieved, but the labeling process becomes tedious and reduces operational efficiency
Solution Approach 1:
The patent replaces the mechanical labeling system (attaching physical labels, RFID tags, or two-dimensional codes to goods) with an optical scanning system. The transport robot uses its carrying apparatus to directly scan and acquire imaging information of the goods' barcodes or codes during the retrieval process, eliminating the need for pre-labeling operations while maintaining accurate goods identification.
2Loss of information
If transport robots perform pre-labeling operations on containers, then goods can be located and retrieved, but the labeling process consumes time and reduces retrieval speed
Solution Approach 1:
The patent applies preliminary action by having the transport robot acquire the code information of the target goods in advance through scanning before the actual retrieval operation begins. The control system then uses this pre-acquired information to guide the carrying apparatus to the correct position, enabling direct retrieval without time-consuming labeling steps during the operation.
Solution Approach 2:
The patent introduces an intermediary mechanism where the carrying apparatus serves dual functions: both as the retrieval tool and as the scanning device. By integrating the barcode scanning capability into the carrying apparatus itself, the system eliminates the need for separate labeling operations and directly acquires goods information during the normal retrieval process.
3Reliability
If transport robots use manual labeling processes for goods identification, then goods can be tracked in the intelligent storage system, but the complexity of the system increases due to labeling requirements
Solution Approach 1:
The patent applies universality by making the carrying apparatus multi-functional. It serves both as the mechanical tool for retrieving goods and as the scanning device for acquiring goods information. This consolidation eliminates the need for separate labeling equipment and processes, reducing system complexity while maintaining reliable goods tracking through the integrated scanning capability.

AI summary
The present disclosure provides a control method for goods retrievement and storage, a control apparatus, and a transport robot. The control method for goods retrievement includes: receiving a retrievement instruction, and acquiring locating information of target goods according to the retrievement instruction; moving a transport robot to a target position according to the locating information; obtaining status information of the target goods and/or position relationship information between a carrying apparatus and the target goods; and adjusting a position and posture of the carrying apparatus according to the status information and/or the position relationship information, and causing the carrying apparatus to take out the target goods. According to the present disclosure, the position of the target goods can be accurately determined by obtaining status information of the target goods and/or position relationship information between the carrying apparatus and the target goods, so that the target goods can be accurately retrieved.
