Autonomous Mobile Body Inspection via Control and Sensor Deviation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an effective technique to inspect movable bodies that operate autonomously or through remote control, ensuring appropriate detection of abnormalities in their operation.
Innovation Solution
An inspection system that includes a processor configured to generate control instructions for the movable body and execute an abnormality process if differences between physical quantities related to the body's operation exceed predetermined criterion values, using internal and external sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If remote or autonomous inspection is implemented for movable bodies, then inspection capability is improved, but reliability of abnormality detection deteriorates due to difficulty in appropriately detecting abnormalities
Solution Approach 1:
The system compares multiple physical quantities (first physical quantity from control instruction, second physical quantity from internal sensor, third physical quantity from external sensor) to detect abnormalities. This feedback mechanism continuously monitors the movable body's operation and compares actual values against expected values, enabling reliable autonomous inspection by identifying deviations that indicate abnormal conditions
Solution Approach 2:
The system introduces an intermediary comparison process that mediates between control instructions and actual sensor readings. By comparing physical quantities through this intermediary step, the system can detect abnormalities without requiring direct human intervention, thus maintaining reliable detection in remote or autonomous scenarios
2Measurement precision
If multiple physical quantities are compared for abnormality detection, then inspection accuracy is improved, but device complexity increases
Solution Approach 1:
The processor serves multiple functions: it generates control instructions, calculates physical quantities from various sensors, compares these quantities to determine abnormalities, and executes abnormality processes. This multi-functionality allows the system to achieve high inspection accuracy through multiple physical quantity comparisons without proportionally increasing device complexity, as a single processor handles all these tasks

AI summary
An inspection system of remotely or autonomously inspecting a mobile body movable through unattended operation includes: a processor that generates and outputs a control instruction that causes the mobile body to operate; and executes an abnormality process in a case where a difference obtained by comparing at least two of physical quantities for the mobile body as a target is more than a criterion value, the physical quantities including a first physical quantity related to operation of the mobile body achieved according to the control instruction, the first physical quantity being calculated using the control instruction, a second physical quantity related to the operation, calculated using a detection result from an internal sensor mounted on the mobile body, and a third physical quantity related to the operation, calculated using a detection result from an external sensor positioned outside the mobile body.
