Robot Arm Error Display With Chronological Value Graphs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices for robot arms fail to intuitively convey the type of error occurring during operations, merely displaying various graph information without clear indication of the specific error type.
Innovation Solution
A control device and display device that acquires chronological operation information of a robot arm, determines the error type, and displays corresponding actual measured values chronologically to intuitively convey the error through graphical and simulation representations.

Engineering Contradiction Analysis
1Loss of information
If various graph information related to current values, positions, speeds, accelerations, position deviations, speed deviations, and acceleration deviations are displayed, then comprehensive error information is provided, but it becomes difficult to intuitively grasp what kind of error has occurred
Solution Approach 1:
The display is segmented into multiple regions: a notification area showing the error type in large text, a graph display area showing chronological changes in actual measured values, and a simulation image area showing the robot arm's pose. This segmentation allows comprehensive error information to be presented while making the error type immediately recognizable through the notification area.
Solution Approach 2:
The notification area uses distinct color coding to indicate different error types (e.g., red for speed abnormalities, yellow for position abnormalities, green for torque abnormalities). This color-changing approach enables operators to quickly and intuitively grasp the error type at a glance while maintaining comprehensive information display.
2Quantity of substance
If all operation information is displayed simultaneously, then complete data is available, but the operator cannot quickly identify the relevant error information
Solution Approach 1:
The display divides information into prioritized segments: the notification area prominently displays the error type determination result, the graph area shows chronological changes in actual measured values, and the simulation area depicts the robot arm's pose. This segmentation enables operators to quickly identify relevant error information without being overwhelmed by all operation data.
Solution Approach 2:
The system performs preliminary determination of the error type based on operation information before displaying it to the operator. The notification area is pre-configured to show the determined error type in large, prominent text, so that when an error occurs, the operator immediately sees the identified error type without needing to search through comprehensive data.
3Measurement precision
If detailed graph information is displayed, then comprehensive analysis is possible, but the display becomes complex and difficult to interpret quickly
Solution Approach 1:
The display is divided into functionally distinct segments: a notification area for error type identification, a graph display area for chronological value analysis, and a simulation image area for pose visualization. Each segment serves a specific purpose, maintaining measurement precision while reducing overall display complexity through functional organization.
Solution Approach 2:
The system adds dimensional variety to the display by incorporating not only graphical charts but also simulation images of the robot arm's pose. This multi-dimensional presentation approach (combining 2D graphs with 3D-like simulation visuals) provides comprehensive error analysis while making the information more engaging and easier to interpret quickly.

AI summary
A control device includes an acquisition section configured to acquire chronological operation information of a robot arm to which a plurality of arms are rotatably coupled; a determination section configured to determine, when an error occurs in the operation of the robot arm, a type of the error based on the operation information; and a display control section configured to control a display section to display chronological change information in actual measured values of the operation information corresponding to the type of error determined by the determination section based on error information in which the operation information and the type of error are associated with each other.
