Delivery Robot Camera-Based Item Detection for Partitioned Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Delivery robots face challenges in safely transporting items over uneven terrain and navigating obstacles, particularly in environments where high manufacturing costs and limited space are concerns, requiring advanced sensors and safety features to prevent item loss and ensure safe operation.
Innovation Solution
A delivery robot equipped with a camera that determines the presence of items inside its storage compartment using image analysis, along with elastic sensors and a sliding shelf system, allows for safe operation by detecting obstacles and preventing item loss, and includes a locking mechanism to ensure safe delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a delivery robot is equipped with advanced sensors and safety features to detect obstacles and prevent item loss, then the safety and reliability of item transport is improved, but the manufacturing cost increases
Solution Approach 1:
The camera system serves multiple functions: it detects obstacles during navigation, verifies item presence in storage, and monitors the delivery environment. This multi-functionality reduces the need for separate specialized sensors, thereby improving safety while controlling manufacturing costs.
Solution Approach 2:
The robot uses its own camera system to perform safety checks and obstacle detection without requiring external monitoring equipment. The system self-verify item presence and self-navigate by detecting obstacles, reducing the need for additional safety infrastructure and lowering overall system cost.
2Reliability
If the delivery robot uses multiple sensors to make quick decisions for obstacle avoidance, then the response speed and safety are improved, but the device complexity increases
Solution Approach 1:
A single camera system performs multiple detection tasks including obstacle detection, item verification, and environmental monitoring. This consolidates what would traditionally require multiple specialized sensors into one multi-functional device, reducing system complexity while maintaining comprehensive safety capabilities.
Solution Approach 2:
The patent combines obstacle detection, item presence verification, and navigation functions into a unified camera-based system. By merging these functions into a single integrated system rather than using separate sensors for each task, the overall device complexity is reduced while maintaining quick response capabilities.
3Reliability
If the delivery robot equips with a camera system for item detection, then the reliability of item transport is improved, but the device complexity increases
Solution Approach 1:
The camera system is designed to serve multiple purposes: verifying item presence in storage, detecting obstacles during transport, and monitoring the delivery environment. This multi-functionality justifies the added complexity by providing comprehensive safety and reliability improvements through a single integrated system rather than multiple separate components.

AI summary
Provided is a delivery robot including a body housing including a storage defined therein and a body opening defined in a front surface thereof, a door that operates in a closed state to cover the body opening or an open state to open the body opening, a detachable partition partitioning the inside of the storage in a left and right direction, an internal camera disposed inside the storage overlapping the partition and facing rearwards, and a controller that determines whether an item exists inside the storage based on an image collected from the internal camera. The controller determines whether the item exists by separating the image of the internal camera into a left image and a right image when the partition is mounted, and determines whether the item exists by analyzing the image of the internal camera as a whole when the partition is detached.
