Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual pickup is replaced by robot pickup to improve logistics efficiency, then productivity increases, but positioning accuracy deteriorates leading to high failure rate
Solution Approach 1:
The patent replaces manual mechanical positioning with an automated vision-based positioning system. The camera captures images of slot identifiers and goods identifiers, and the processor automatically determines the target slot position and goods position within the slot, eliminating reliance on manual positioning skills and achieving consistent, accurate results.
Solution Approach 2:
The patent introduces an intermediary vision system consisting of a camera and image processing module. This intermediary captures visual information about slot identifiers and goods identifiers, processes the images to extract position information, and provides accurate positioning data to the pickup robot, bridging the gap between automated operation and precise positioning.
2Measurement precision
If robot travels to each slot to acquire target image for accurate identification, then positioning accuracy improves, but time consumption increases
Solution Approach 1:
The patent performs preliminary image acquisition by capturing the target image containing slot identifier and goods identifier before the pickup operation. The processor analyzes these identifiers in advance to determine the target slot position and goods position within the slot, so that when the robot arrives at the target slot, the positioning is already complete, reducing on-site time consumption.
Solution Approach 2:
The patent creates a visual copy of the slot and goods information through image capture. The camera captures the slot identifier and goods identifier, creating a digital representation that the processor analyzes to determine position information. This copying approach allows accurate positioning without requiring complex physical measurement or trial-and-error searching.
3Manufacturing precision
If image processing is performed to filter goods identifier from target image, then pickup accuracy improves, but device complexity increases
Solution Approach 1:
The patent segments the image processing task into distinct functional modules: the image processing module filters and extracts the goods identifier from the target image, while the position determining module calculates the position information based on the extracted identifier. This segmentation allows each module to focus on a specific function, improving pickup accuracy while keeping the overall system manageable through modular design.

AI summary
The present disclosure provides a pickup robot, a pickup method, and a computer-readable storage medium. First, obtain a target image captured when a pickup component moves to each slot where a commodity is stored; then, when it is determined, on the basis of the slot identifier in the target image, that the current slot is a target slot which stores a commodity to be picked, screen a commodity identifier from the target image; when the commodity identifier is obtained by means of screening, determine, on the basis of the commodity identifier, the position information of the commodity to be picked up in the target slot; finally, pick up, on the basis of the position information, said commodity from the target slot. In the technical solution above, the target slot where the commodity to be picked up is stored, and the position information of said commodity in the target slot can be accurately determined by using the slot identifier and the commodity identifier, and said commodity can be accurately picked up on the basis of the determined position information, thereby effectively improving the pickup success rate, and also helping to improve the logistics efficiency of logistics industry.
