Transport Control Using Object Feedback for Slippage Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport control methods for automated guided robots and vehicles fail to accurately transport objects due to variations in floor surface conditions, object mass, and slipping, leading to inappropriate transport operations.
Innovation Solution
A transport control method that obtains operation information from the object and identifies second control information to adjust transport parameters, such as velocity and pressure, based on actual movement characteristics, enabling more precise control of transport apparatuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard transport control methods are used, then the transport apparatus can operate with simple control logic, but the object cannot be transported appropriately due to variations in floor surface, slipping, and object mass
Solution Approach 1:
The patent implements feedback control by detecting the actual position of the transported object and comparing it with the target position. The control apparatus adjusts transport parameters (velocity, acceleration, pressure) based on the detected position deviation, enabling accurate transport despite variations in floor surface, slipping, and object mass.
Solution Approach 2:
The control apparatus dynamically changes transport parameters including velocity, acceleration, and pressing force based on detected object position and operational conditions. This parameter adjustment allows the system to adapt to varying conditions such as floor unevenness, slipping, and different object masses to maintain transport accuracy.
2Reliability
If transport parameters are adjusted to accommodate varying conditions, then transport accuracy improves, but the response time and control delay increase
Solution Approach 1:
The control apparatus pre-calculates and stores optimal transport parameters for different operational conditions and object types. When transporting an object, the system quickly retrieves pre-computed parameters based on object identification, reducing calculation time while maintaining transport accuracy.
Solution Approach 2:
The system continuously monitors object position and provides real-time feedback to the control apparatus. This enables dynamic adjustment of transport parameters during movement, allowing the system to respond quickly to position deviations and maintain accuracy without excessive delay.
3Manufacturing precision
If the control apparatus monitors object position continuously, then transport precision is maintained, but the measurement and detection complexity increases
Solution Approach 1:
The patent introduces a position detection device as an intermediary between the transport apparatus and the control apparatus. This detector automatically measures object position and provides data to the control system, simplifying the detection process while maintaining high transport precision through continuous monitoring.
