Transfer Robot Package Verification via Dual Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transfer robots may inadvertently convey objects other than the predetermined package due to lack of effective verification methods, leading to incorrect loading on the load-carrying platform.
Innovation Solution
Incorporating a first determining device to assess if an object is loaded on the platform and a second determining device to confirm the presence of the predetermined package, with sensors and a controller to prevent conveyance and issue warnings when the package is not loaded, utilizing features like recessed and projecting portions, load sensors, and temperature sensors for accurate identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no verification method is used, then the transfer robot can operate simply and quickly, but incorrect objects may be conveyed on the load-carrying platform
Solution Approach 1:
The verification system is divided into two independent determining devices: a first determining device that detects whether any object is present on the platform, and a second determining device that verifies whether the specific predetermined package is present. This segmentation allows each device to focus on a specific verification task, improving overall reliability while keeping individual device complexity manageable
Solution Approach 2:
Physical features such as recessed portions and projecting portions are introduced as intermediaries between the package and the sensing system. These features create detectable interactions (e.g., a projecting portion of the package fitting into a recessed portion of the platform) that enable reliable detection without requiring complex verification mechanisms
2Measurement precision
If physical verification features are added to the platform, then package verification accuracy improves, but the platform structure becomes more complex
Solution Approach 1:
Rather than making the entire platform complex, the verification features (recessed portions and projecting portions) are introduced only at specific local locations on the platform where package interaction occurs. This localized approach provides precise package identification capability while minimizing overall structural complexity
Solution Approach 2:
The verification system utilizes asymmetric physical features - a recessed portion in the platform and a corresponding projecting portion on the package - that create a unique geometric relationship. This asymmetry ensures that only the correct predetermined package can be properly verified, enhancing measurement precision through distinctive physical characteristics

AI summary
A transfer robot that conveys a predetermined package loaded on a load-carrying platform includes: the load-carrying platform; a first determining device configured to determine whether an object is loaded on the load-carrying platform; a second determining device configured to determine whether the predetermined package is loaded on the load-carrying platform; and at least one of a controller configured to control the transfer robot such that the transfer robot performs a predetermined operation and a warning device configured to issue a warning, when the first determining device determines that the object is loaded on the load-carrying platform and the second determining device determines that the predetermined package is not loaded on the load-carrying platform.
