Delivery Robot Stop Positioning Around Shelf Obstacles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Delivery robots face challenges in determining an appropriate stop position near storage shelves when obstacles are present, preventing them from successfully storing articles.
Innovation Solution
A delivery system equipped with a detection unit and control unit that determines a stop position and direction for the robot relative to the storage shelf based on the obstacle's position, allowing the robot to store articles without removing the obstacle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the delivery robot stops in a predetermined area near the storage shelf, then the robot can successfully store articles in the storage shelf, but the robot cannot determine an appropriate stop position when an obstacle is present in the predetermined area
Solution Approach 1:
The patent makes the stop position dynamic by allowing the delivery robot to determine its stop position based on the detected obstacle position. Instead of using a fixed predetermined area, the stop position is adjusted dynamically according to the environment, enabling the robot to adapt to obstacles while maintaining reliable article storage functionality.
2Ease of operation
If the delivery robot requires a predetermined stop area near the storage shelf, then the robot can execute storage operations, but the system must remove obstacles from this area which increases system complexity
Solution Approach 1:
The patent converts the harmful effect of obstacles into a beneficial adaptation mechanism. Instead of requiring obstacle removal, the system uses obstacle detection information to dynamically determine stop positions, transforming the obstacle from a problem into a reference point for position calculation, thereby simplifying the system by eliminating the need for obstacle removal mechanisms.
3Device complexity
If the delivery robot uses a fixed stop position approach, then the control system is simple, but the robot cannot adapt to obstacles present in the predetermined area
Solution Approach 1:
The patent changes the parameter of stop position from a fixed value to a dynamically calculated value based on obstacle position. The control unit calculates the stop position by considering the distance and direction to the detected obstacle, transforming the control approach from simple fixed-position control to adaptive control that responds to environmental parameters.

AI summary
A delivery system includes a storage shelf, a delivery robot capable of moving to the storage shelf and delivering an article to the storage shelf, a detection unit that detects an obstacle present near the storage shelf, and a control unit that controls an operation of the delivery robot. The control unit is configured to, when the detection unit detects an obstacle present in a predetermined area near the storage shelf and the control unit determines that the delivery robot can deliver an article to the storage shelf, determine a stop position and a stop direction of the delivery robot relative to the storage shelf based on a position of the detected obstacle and a position of the storage shelf.
