Robot Arm Teaching Interface for Accurate Attitude Programming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing teaching devices for robots struggle to provide accurate and efficient methods for beginners to teach robot arm attitudes, as they only display coordinate system names, making it difficult to select the correct coordinate system for desired robot attitudes.
Innovation Solution
A teaching device with a display unit showing first and second operation units for designating the proximal and distal arms of a robot, allowing users to change the robot arm's attitude and position of control points, and an operation program generation unit that generates programs based on these designations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only coordinate system names are displayed, then the device complexity is reduced, but the ease of operation deteriorates for beginners
Solution Approach 1:
The patent introduces graphical icons representing robot arm attitudes as an intermediary between the coordinate system names and the beginner user. These icons visually depict the actual attitudes (positions and orientations) that each coordinate system command will produce, allowing beginners to understand the effect of each command without needing to comprehend complex coordinate system transformations. This mediator bridges the gap between simple operation and accurate control.
Solution Approach 2:
The patent creates visual copies (graphical icons) of the robot arm attitudes that will result from each coordinate system command. Instead of directly showing abstract coordinate system names, the system generates and displays visual representations (copies) of the actual arm positions and orientations, making it easier for beginners to select the correct attitude by visually matching the desired pose with the displayed icons.
2Manufacturing precision
If multiple operation units are provided for attitude designation, then the manufacturing precision of robot arm attitude is improved, but the device complexity increases
Solution Approach 1:
The patent segments the attitude designation function into multiple specialized operation units: a first operation unit for designating the proximal arm attitude and a second operation unit for designating the distal arm attitude. Each operation unit is optimized for specific teaching scenarios, allowing beginners to select the appropriate unit based on which part of the robot arm needs adjustment. This segmentation provides precise control over different parts of the robot arm while keeping each individual operation unit relatively simple to understand and use.

AI summary
A teaching device generating an operation program for executing an operation of a robot having a base and a robot arm including a proximal arm coupled to the base and a distal arm coupled to a side opposite to the base of the proximal arm is provided. The teaching device includes: a display unit displaying a first operation unit accepting an operation of designating the proximal arm of the robot arm and changing an attitude of the robot arm and a second operation unit accepting an operation of designating a position of a control point set for the robot arm and changing the attitude of the robot arm; and an operation program generation unit generating the operation program, based on the attitude designated at the first operation unit or the second operation unit.
