Robot Work Teaching via Pose and Operation Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot teaching systems require manual and repetitive input of commands for grasping and operating work target objects and tools, leading to increased man-hours for developing teaching programs as tasks become more complex.
Innovation Solution
A work teaching device for robots that includes units to measure and detect the position, grasping, functional operation, and work state of objects, generating a teaching program in synchronization with a teacher's actions, allowing for automatic program generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual input of commands for grasping and operating work target objects and tools is used, then the robot can execute complex tasks, but the man-hours for developing teaching programs increases
Solution Approach 1:
The system uses motion capture technology to record and copy the teacher's natural hand movements, grasping actions, and tool operations. Instead of manually programming each command, the robot learns by observing and reproducing the teacher's demonstrated actions, automatically generating teaching programs from the captured motion data
Solution Approach 2:
The patent replaces the mechanical process of manual command input with an optical measurement system. Motion capture cameras and sensors automatically detect and record the teacher's movements, substituting the manual programming mechanism with an automated visual detection and data processing system
2Manufacturing precision
If detailed commands for each process step are manually input, then the robot can perform precise operations, but the debugging work and input work by the teacher increases
Solution Approach 1:
The system enables self-service teaching where the robot automatically generates its own teaching program by observing the teacher's demonstrations. The motion capture system automatically records positions, postures, and operation timings, eliminating the need for the teacher to manually input and debug detailed commands for each step
3Extent of automation
If synchronization between motion measurement and operation detection is implemented, then automatic program generation is enabled, but the system complexity increases
Solution Approach 1:
The patent merges the motion measurement function and operation detection function into a unified teaching system. The motion capture cameras and sensors work together with detection units that simultaneously track both the teacher's movements and their operations, combining multiple functions into an integrated system that generates teaching programs automatically

AI summary
A work teaching device for a robot that teaches work by a teacher to the robot is configured to include a teaching pose measurement unit that measures a position and posture of an object grasped by the teacher, a positioning detection unit for detecting that the object moved by the teacher is positioned, a grasping motion detection unit for detecting that the object is grasped by the teacher, a functional operation detection unit for detecting that the teacher operates a function of the object, a work state confirming motion detection unit that detects that confirmation of a work state of the object by the teacher is performed, a teaching program generation unit that receives signals from the teaching pose measurement unit, the positioning detection unit, the grasping motion detection unit, the functional operation detection unit, and the work state confirming motion detection unit and generates a teaching program for the robot in which the signals are divided for each movement of the teacher, and a teaching program execution unit that executes the teaching program generated by the teaching program generation unit.
