Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robot teaching methods, whether using a teaching pendant or direct teaching, are difficult for non-experts and require manual movement of the robot, making it challenging to perform tasks that require precise positional adjustments, especially with heavy robots.
Innovation Solution
A teaching device that includes an image acquisition unit, movement control unit, and teaching information acquisition unit, allowing users to teach robots by acquiring and processing images of the manipulation target object and reference target object, enabling automatic movement of the robot to specified positions without direct manual manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct teaching or teaching pendant is used, then the robot can be taught to perform tasks, but the teaching process becomes difficult and requires extensive knowledge or manual movement
Solution Approach 1:
The patent replaces manual mechanical teaching methods (direct teaching and teaching pendant operation) with an automated image-based teaching system. The system uses image acquisition devices to capture the robot's movement and automatically extracts teaching information, eliminating the need for operators to manually manipulate the robot or understand complex teaching pendant operations.
Solution Approach 2:
The patent creates a visual copy of the robot's movement through image acquisition. By capturing images of the robot's actual movement and automatically processing these images to extract teaching information, the system creates an automated record of the teaching process that can be stored and reused without requiring repeated manual teaching operations.
2Measurement precision
If manual movement of the robot is required for teaching, then teaching can be performed, but it becomes difficult to perform precise positional adjustments and teaching of heavy robots
Solution Approach 1:
The patent replaces manual mechanical positioning with automated image-based positioning. The image acquisition device captures the robot's position, and the teaching information extraction unit automatically processes these images to determine precise teaching positions, eliminating the need for manual positioning while achieving high precision.
Solution Approach 2:
The system uses image feedback to automatically determine teaching information. By continuously acquiring images of the robot's movement and processing these images to extract positional data, the system provides automated feedback that enables precise positional adjustments without manual intervention.
3Adaptability or versatility
If teaching pendant manipulation is used, then the robot can be controlled during teaching, but extensive knowledge of the teaching pendant and robot movement is required
Solution Approach 1:
The patent replaces the teaching pendant interface with an automated image processing interface. Instead of requiring operators to understand teaching pendant operations and robot kinematics, the system automatically captures images and extracts teaching information, making the teaching process accessible to users without specialized knowledge.
Solution Approach 2:
The system performs self-service by automatically extracting teaching information from captured images without requiring manual interpretation or manipulation. The teaching information extraction unit autonomously processes the image data to generate teaching information, eliminating the need for operators to have extensive knowledge of robot movement and teaching procedures.

AI summary
A teaching device includes an image acquisition unit which acquires an image including a manipulation target object which is linked to operations of an arm of a robot and a teaching position of the manipulation target object, a movement control unit which controls the arm to move the manipulation target object in the image to the teaching position, and a teaching information acquisition unit which acquires a state of the arm in a state in which the manipulation target object in the image is present at the teaching position as teaching information.
