Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robot systems often operate with minimal supervision, leading to challenges in identifying errors, especially when interacting with peripheral devices, which can accumulate errors over time and are difficult to pinpoint, particularly after reprogramming.
Innovation Solution
A method and system for monitoring robot systems by establishing a communicative connection between peripheral devices and a robot controller, recording and storing operation signals as an operation signal history, allowing for tracking and analysis of system performance and errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If robot systems operate with minimal supervision to maintain productivity, then productivity is improved, but error detection capability deteriorates
Solution Approach 1:
The patent implements a monitoring system that continuously records operation signals from robot controllers and peripheral devices, creating a feedback loop that enables error detection without requiring constant human supervision. The system compares actual operation signals against expected patterns and generates alerts when deviations are detected, maintaining both high productivity and reliable error detection.
Solution Approach 2:
The patent introduces an intermediary monitoring system that acts as a bridge between the autonomous robot system and human operators. This intermediary automatically analyzes operation signals, identifies errors, and only engages human attention when necessary, allowing the robot system to operate autonomously while maintaining error detection capability through the intermediary monitoring layer.
2Adaptability or versatility
If peripheral devices are integrated into robot systems to expand functionality, then adaptability is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal monitoring interface that can handle multiple types of peripheral devices through a common communication protocol. The system records and analyzes operation signals from various devices (conveyors, sensors, safety systems) using the same monitoring architecture, allowing the robot system to integrate diverse peripheral devices without proportionally increasing monitoring complexity.
3Reliability
If operation signals are recorded and stored for monitoring purposes, then error detection capability is improved, but data management complexity increases
Solution Approach 1:
The patent extracts and records only the essential operation signals from robot controllers and peripheral devices that are relevant for error detection. The monitoring system selectively captures key operational parameters rather than all possible data, reducing the volume of data that needs to be managed while maintaining sufficient information for effective error detection and analysis.
