Robot Teaching Display Control for Misalignment Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display techniques for robot operation teaching become overly complex when visualizing position, orientation, and force misalignments simultaneously, hindering intuitive understanding.
Innovation Solution
A display control apparatus that obtains measurement information, generates emphasized display information to highlight key features, and composes it with non-emphasized information to create a composite image for improved visibility, outputting it to a display unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all position misalignment, orientation misalignment, and force information are visualized simultaneously using arrows and graphs, then complete information is provided, but the displayed content becomes very complicated and may impede intuitive understanding
Solution Approach 1:
The patent divides the display content into multiple segments: a background image showing the overall scene, and multiple foreground images showing different aspects (position misalignment, orientation misalignment, force) that can be selectively superimposed. This segmentation allows complete information to be available while avoiding the complexity of showing all elements simultaneously in a single view.
Solution Approach 2:
The patent implements dynamic switching between different display modes where the teacher can select which type of information to emphasize at different times. The display system dynamically adjusts what information is superimposed on the background image based on teaching needs, allowing the complexity level to change dynamically rather than being static.
2Loss of information
If multiple types of measurement information are displayed together, then comprehensive understanding is achieved, but the teacher's intuitive understanding is impeded due to overwhelming visual complexity
Solution Approach 1:
The patent applies partial action by displaying only the necessary subset of information at any given time rather than all information simultaneously. The teacher can select which measurement information (position, orientation, force) to display based on current teaching needs, providing comprehensive understanding over time while maintaining intuitive understanding at any moment.
Solution Approach 2:
Different regions or aspects of the display have different qualities - the background image provides contextual information while foreground images provide specific measurement information. This local differentiation allows the display to be both comprehensive (covering all aspects) and intuitive (clear presentation of each aspect in its appropriate context).

AI summary
A display control apparatus operable to display an operation of a robot comprising: an obtaining unit configured to obtain measurement information of a processing target that includes at least one of the robot and a target that the robot operates; an emphasizing unit configured to generate emphasized display information that emphasizes a feature of a portion of the processing target, based on the measurement information; a composition unit configured to generate composite display information in which the emphasized display information and non-emphasized display information other than the emphasized display information are composed; and an output unit configured to output the composite display information to a display unit.
