Solution Overview
Problem
Conventional robot vision systems require labor-intensive reattachment of imaging cameras and image processing units across multiple robots, degrading efficiency in measuring and correcting 3D relative position/orientation errors.
Innovation Solution
A robot system with a vision sensor that uses a communication network to transmit image data between an imaging section and image processing section, allowing for wireless or radio transmission and eliminating the need for physical reconnection, enabling efficient measurement and correction of 3D relative position/orientation errors across multiple robots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single image processing unit is shared across multiple robots, then device complexity is reduced, but the time required for detaching and reattaching the imaging camera and image processing unit increases significantly
Solution Approach 1:
The patent replaces the mechanical connection system (signal cables physically connecting imaging camera to image processing unit) with a wireless communication system. The imaging camera transmits image data via radio waves to the image processing unit, eliminating the need for physical cable connections and enabling rapid switching between multiple robots without detaching or reattaching components.
2Ease of operation
If the imaging camera is permanently connected to one robot, then ease of operation is improved, but adaptability across multiple robots deteriorates
Solution Approach 1:
The patent makes the imaging camera and image processing unit universal components that can serve multiple robots. Through wireless communication, the same imaging camera can be attached to different robots and the same image processing unit can process data from different cameras, enabling one piece of equipment to perform multiple functions across different robot systems.
3Reliability
If signal cables are used to connect the imaging camera to the image processing unit, then reliability of connection is improved, but ease of operation deteriorates due to labor-intensive handling
Solution Approach 1:
The patent substitutes the mechanical cable connection system with an electromagnetic communication system. Image data is transmitted wirelessly via radio waves from the imaging camera to the image processing unit, maintaining reliable data transmission while completely eliminating the manual handling of heavy signal cables during attachment and detachment operations.
