Solution Overview
Problem
There is no technology capable of measuring the movement accuracy of autonomous mobile vehicles, such as autonomous mobile robots (AMR) or automated guided vehicles (AGV), after they are purchased, limiting the ability to verify true movement accuracy.
Innovation Solution
An accuracy measurement kit is provided, comprising at least one marker with a reference pattern, a light beam device, an image capture device, and a calculating device. The kit measures the accuracy of the autonomous mobile vehicle by capturing images of light spots and markers, processing these images to calculate X-axis and Y-axis distances, and determining offsets to achieve accurate movement measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If no measurement technology is provided for autonomous mobile vehicles, then the device complexity remains low, but the measurement precision of movement accuracy cannot be obtained
Solution Approach 1:
The measurement system is segmented into distinct functional modules: light beam device for emitting reference beams, image capture device for capturing marker positions, and calculating device for computing movement accuracy. This segmentation allows each component to be optimized independently while maintaining overall measurement precision.
Solution Approach 2:
A marker with reference pattern serves as an intermediary between the autonomous mobile vehicle and the measurement system. The marker is attached to the vehicle and captured by the image capture device, enabling indirect measurement of vehicle position and movement accuracy without requiring direct sensors on the vehicle.
2Reliability
If manual specifications are used to obtain movement accuracy, then the device complexity remains low, but the reliability of accuracy information cannot be verified
Solution Approach 1:
The system implements feedback by capturing the marker position through the image capture device, comparing it with the known reference pattern, and calculating the actual movement accuracy. This closed-loop feedback mechanism verifies the reliability of movement accuracy information by providing measurable, objective data rather than relying on manufacturer specifications.
Solution Approach 2:
The patent replaces manual verification methods with an automated optical measurement system. The light beam device, image capture device, and calculating device work together to automatically measure and verify movement accuracy, eliminating the need for manual inspection of manufacturer specifications and providing reliable, objective measurement data.
3Productivity
If no accuracy measurement capability is provided, then the ease of operation remains high, but the productivity through collision prevention is reduced
Solution Approach 1:
The autonomous mobile vehicle participates in its own measurement process by carrying the marker that is captured by the image capture device. The vehicle's own movement and position information are used to calculate its movement accuracy, enabling self-verification without requiring external measurement equipment or complex operational procedures.
