Robot Teaching Interface With Voice-Key Input Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In industrial robot teaching, operators often face a burden as they need to perform tasks alongside teaching the robot, and existing teaching devices do not effectively reduce this burden by allowing seamless switching between key operation and voice input.
Innovation Solution
A robot teaching device equipped with a display, operation keys, a microphone for voice input, voice recognition, and a storage system that associates voice commands with corresponding actions, enabling operators to switch between key and voice input for efficient teaching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice input function is added to teaching device, then operator burden is reduced, but device complexity increases
Solution Approach 1:
The patent combines voice input functionality with the existing key operation input interface into a unified teaching device. The voice recognition section integrates with the operation keys and display device, allowing operators to switch between voice and key input modes without requiring separate devices. This merging approach reduces operator burden while managing device complexity through integrated design.
Solution Approach 2:
The teaching device is designed to perform multiple functions: it can accept both traditional key operations and voice inputs for robot teaching. The operation key serves dual purposes as both a physical input device and a control interface for voice input mode. This multi-functionality allows the same device to reduce operator burden through voice input while maintaining compatibility with existing teaching workflows.
2Productivity
If switching between key operation and voice input is enabled, then teaching efficiency is improved, but operation complexity increases
Solution Approach 1:
The input changeover switch enables dynamic switching between key operation mode and voice input mode. The device adapts its input acceptance based on the current mode selected by the operator. This dynamic capability allows operators to choose the most efficient input method for different teaching scenarios, improving overall teaching efficiency while providing clear mode transitions to manage operation complexity.
3Speed
If voice recognition processing is implemented, then input speed is increased, but processing accuracy may be reduced
Solution Approach 1:
The display device provides visual feedback to operators during voice recognition processing, showing recognized commands and current input mode. This feedback mechanism allows operators to verify voice recognition accuracy in real-time and correct any misrecognitions. The system balances input speed through voice recognition with accuracy through visible confirmation and the ability to switch to precise key input when needed.

AI summary
A robot teaching device includes: a display device; an operation key formed of a hard key or a soft key and including an input changeover switch; a microphone; a voice recognition section; a correspondence storage section storing each of a plurality of types of commands and a recognition target word in association with each other; a recognition target word determination section configured to determine whether a phrase represented by character information includes the recognition target word; and a command execution signal output section configured to switch, in response to the input changeover switch being operated, between a first operation in which a signal for executing the command corresponding to an operation to the operation key is outputted and a second operation in which a signal for executing the command associated with the recognition target word represented by the character information is outputted.
