Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robots that perform tasks based on images struggle with accuracy and efficiency when the position and posture of objects in the workspace change, as they require re-teaching and can't accurately adapt to shifts in the workspace environment.
Innovation Solution
A robot system that uses an image pickup section with a transparent member between the robot and the workspace, allowing it to operate on picked-up images to improve efficiency and accuracy by correcting for distortions and maintaining precise positioning and posture calculations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a transparent member is disposed between the robot and the workspace, then the robot can improve efficiency and accuracy of work by operating on picked-up images, but the transparent member causes distortion in the picked-up images that affects measurement precision
Solution Approach 1:
The patent introduces a reference image as an intermediary element to bridge the distorted picked-up image and the actual workspace. The reference image, captured without the transparent member causing distortion, serves as a mediator to establish accurate correspondence between image coordinates and real-world positions, thereby compensating for the distortion introduced by the transparent member.
Solution Approach 2:
The patent changes the parameter of image coordination by establishing a coordinate transformation relationship between the picked-up image (with distortion) and the reference image (without distortion). This parameter transformation allows the system to convert distorted coordinates into accurate real-world coordinates, maintaining measurement precision despite the presence of the transparent member.
2Ease of operation
If the robot operates on picked-up images through the transparent member, then it can perform work in the workspace, but the distortion caused by the transparent member makes it difficult to accurately determine object positions and postures
Solution Approach 1:
The patent creates a reference image that copies the workspace environment without the distortion caused by the transparent member. This reference copy is then used to correct and interpret the distorted picked-up images, allowing the robot to accurately determine object positions and postures despite operating through the transparent barrier.
Solution Approach 2:
The reference image acts as an intermediary that translates between the distorted visual information from the picked-up image and the actual physical positions in the workspace. By using this intermediary reference, the system can accurately map image coordinates to real-world coordinates without being affected by the transparent member's distortion.
3Productivity
If the image pickup section is moved into the workspace to pick up images, then the robot can improve efficiency and accuracy of work, but it requires the robot to enter and exit the workspace which increases complexity
Solution Approach 1:
The patent segments the image acquisition function from the robot's main body by using a separate, movable image pickup section. This allows the image pickup section to be independently positioned and moved into the workspace without requiring the entire robot system to undergo complex reconfiguration, thereby reducing overall system complexity while maintaining improved work efficiency.
