Robot Arm Teaching Interface With Visual Joint-Angle Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing teaching devices for robots struggle to clearly convey how the operation of touch keys translates to specific attitudes of robot arms, making it difficult for workers to effectively program robot movements.
Innovation Solution
A teaching device that displays icons representing different attitudes of a robot arm's joints, allowing workers to designate and generate an operation program based on these attitudes, using a user-friendly interface with sliders and buttons to adjust joint angles, enabling accurate and intuitive programming.

Engineering Contradiction Analysis
1Ease of operation
If touch keys are used for robot arm teaching, then the operation interface is simplified, but it becomes difficult for workers to understand what operation leads to what robot attitude
Solution Approach 1:
The system displays icons representing the robot arm's current attitude on the display unit, providing visual feedback to the worker. When a touch key is operated, the corresponding icon updates to show the new attitude, creating a direct visual feedback loop that helps the worker understand the relationship between their operation and the robot's response.
Solution Approach 2:
Icons are introduced as intermediary visual elements between the touch keys and the actual robot arm. These icons serve as a mediator that translates abstract key presses into concrete visual representations of robot attitudes, making the operation-attitude relationship more comprehensible.
2Loss of information
If detailed robot arm attitude information is displayed, then workers can understand the operation better, but the device complexity increases
Solution Approach 1:
The robot arm is divided into multiple segments (first arm and second arm), and separate icons are provided for each segment's attitude representation. This segmentation allows detailed information to be displayed in a structured, organized manner that avoids overwhelming the user with a single complex visual element.
Solution Approach 2:
Instead of displaying complex numerical data or detailed mechanical diagrams, the system uses two-dimensional icons on the display unit to represent three-dimensional robot arm attitudes. This dimensional transformation simplifies the visual representation while retaining essential attitude information.

AI summary
A teaching device includes: a display unit displaying a first icon showing a first attitude of a robot arm, a second icon showing a second attitude of the robot arm, and a first operation unit for performing an operation of designating a third attitude of the robot arm, the first attitude being a state where an angle formed by a first arm and a second arm of the robot arm is a first angle, the second attitude being a state where the angle formed by the first arm and the second arm is a second angle that is different from the first angle, the third attitude being a state where the angle formed by the first arm and the second arm is a third angle equal to or greater than the first angle and equal to or smaller than the second angle; and an operation program generation unit generating the operation program, based on the third attitude designated at the first operation unit.
