Robotic Object Update Mechanism for Misdetection Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robotic systems face challenges in adapting to unexpected conditions, such as incorrect object identification, which can lead to errors in motion planning and execution, resulting in collisions or grip failures during object transfer.
Innovation Solution
The robotic system employs a mechanism to register expected objects based on physical characteristics and uses sensors to verify the identity of objects by comparing actual measurements with expected data. If discrepancies are found, the system adjusts its motion plan and updates its registration records accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the robotic system uses object identification to generate motion plans, then the system can automate object transfer tasks, but the system may incorrectly identify objects with similar physical characteristics, leading to detection errors
Solution Approach 1:
The system implements feedback by comparing actual sensor measurements (weight, dimensions) against expected values from registration records. When discrepancies are detected, the system triggers correction procedures including pausing the motion plan, notifying operators, or automatically adjusting parameters to resolve the identification error before execution
Solution Approach 2:
The system performs preliminary verification of object identity by comparing multiple physical characteristics (weight, dimensions, appearance) against pre-stored registration records before generating the motion plan. This preliminary check prevents incorrect identification from propagating through the system
2Measurement precision
If the system verifies object identity by comparing measurements with registration records, then detection accuracy improves, but the system complexity increases due to additional verification steps
Solution Approach 1:
The system uses multi-functional sensors that can measure multiple physical characteristics (weight, dimensions, appearance) simultaneously. A single sensor array performs verification across multiple parameters, reducing the need for separate verification devices and minimizing system complexity while maintaining high detection accuracy
3Reliability
If the robotic system corrects detection errors by pausing and notifying operators, then object transfer reliability improves, but productivity decreases due to manual intervention requirements
Solution Approach 1:
The system dynamically adjusts its response to detection errors based on the severity and type of discrepancy. For minor discrepancies, the system automatically corrects parameters and continues operation. For major discrepancies, the system pauses and notifies operators. This dynamic response strategy maintains high reliability while minimizing productivity loss from manual interventions
Data Source
AI summary
A system and method for determining a misdetection of an object and subsequent response is disclosed. A robotic system may use a motion plan, which is derived based on an initial detection result of a package, to transfer the package from a start location to a task location. During implementation of the motion plan, the robotic system may obtain additional sensor data, which can be used to deviate from the initial motion plan and implement a replacement motion plan to transfer the package to the task location.
