Picking Robot Position Display for Faster Item Location
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Picking robots face challenges in efficiently locating items due to the lack of a fixed placement rule in warehouses, leading to low picking efficiency, especially for pickers unfamiliar with the storage layout.
Innovation Solution
A position display method and apparatus for picking robots that determine the item to be picked, identify the robot and compartment positions, and display their relative relationship in a preset interface, enabling intuitive item location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the picking robot stays at a point near an item without displaying position information, then the robot can simply wait for manual picking, but the picker cannot quickly locate the item among multiple shelves
Solution Approach 1:
The patent introduces a display interface as an intermediary between the picking robot and the picker. This interface visually presents the robot's current position and the item's storage position, enabling the picker to quickly locate the item without physically searching through multiple shelves. The display interface acts as a mediator that transfers position information from the robot's internal state to the picker's visual perception.
Solution Approach 2:
The patent creates a visual copy or representation of the robot's position and the item's location on the display interface. Instead of requiring the picker to physically navigate to the item's location, the system displays a simplified visual model (map or schematic) showing where the robot is and where the item is stored, allowing the picker to mentally translate this information into physical location.
2Productivity
If the picker checks shelves one by one to locate the item, then the picker can ensure accurate item identification, but the picking time increases significantly
Solution Approach 1:
The system performs preliminary action by pre-calculating and displaying the robot's position and the item's storage position before the picker arrives. The display interface is updated in advance with the necessary position information, so when the picker approaches, the information is already ready and visible, eliminating the need for the picker to spend time checking shelves sequentially.
Solution Approach 2:
The display interface provides real-time feedback to the picker about the robot's current position and the item's location. This feedback loop allows the picker to immediately understand where the item is without having to physically search, significantly reducing the time required to locate and pick the item.
3Adaptability or versatility
If multiple shelves are placed around the robot position, then the warehouse can store diverse items, but it becomes difficult for the picker to quickly locate the specific item
Solution Approach 1:
The display interface serves as an intermediary that processes the complex spatial relationships between multiple shelves and the robot. It translates the physical arrangement of shelves and items into a simplified visual representation, making it easier for the picker to detect and understand the item's location without being overwhelmed by the complexity of multiple surrounding shelves.
Solution Approach 2:
The patent transitions from a physical three-dimensional search problem to a two-dimensional visual representation on the display interface. By projecting the spatial relationship onto a graphical plane, the system makes it easier for the picker to perceive and locate the item without having to physically navigate through the complex arrangement of multiple shelves.

AI summary
A position display method, a picking robot, and a storage medium are provided. The method includes: obtaining a picking task, and determining, based on the picking task, an item to be picked, where the picking robot includes at least one container for carrying the item to be picked, the picking robot moves between a plurality of shelves in a warehouse to transport items, the shelf includes a plurality of goods storage compartments for storing different items respectively, and the item to be picked is an item that needs to be manually picked; determining a robot position of the picking robot between the shelves and a compartment position of the goods storage compartment where the item to be picked is located; and displaying, in a preset display interface of the picking robot, a relative position relationship between the compartment position and the robot position.
