Remote Robot Work Audio Filtering for Machining Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote work using robots often results in reduced machining accuracy and efficiency due to insufficient information transfer between the worker and the remote operation robot.
Innovation Solution
A remote work support system that includes a sound collector, a sound generator, and a control device to extract and emphasize specific frequency ranges of sounds generated during the work, allowing the worker to improve accuracy and efficiency by listening to these sounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If remote operation robot is used to perform work from a remote location, then worker safety is improved and operational flexibility is increased, but machining accuracy and work efficiency are likely to be lowered due to reduced information transfer
Solution Approach 1:
The patent introduces sound as an intermediary medium to transfer information from the remote work site to the operator. The sound collector captures acoustic signals generated during machining operations, and the sound generator reproduces these sounds at the operator's location, enabling the operator to perceive work progress and machining states without direct visual contact, thus maintaining machining accuracy while enabling remote operation
Solution Approach 2:
The patent replaces direct visual-mechanical observation with acoustic sensing and reproduction. Instead of requiring the operator to directly see the machining process, the system substitutes this with sound collection, signal processing, and acoustic reproduction, allowing the operator to infer machining states through sound characteristics such as frequency, intensity, and timbre
2Loss of information
If all sounds from the work area are transmitted to the worker, then information completeness is improved, but noise and irrelevant sounds reduce work efficiency
Solution Approach 1:
The patent extracts only the useful sound components from the complex acoustic environment during machining operations. The control device analyzes the collected sounds and selectively outputs only those frequency ranges and sound characteristics that provide meaningful information about work progress and machining states, filtering out irrelevant noise and background sounds that would distract the operator
Solution Approach 2:
The patent applies different processing qualities to different sound components. Rather than uniformly transmitting all sounds, the system enhances specific frequency ranges that contain useful machining information while suppressing or eliminating other frequency ranges that contain noise or irrelevant sounds, creating a differentiated sound output that optimizes information delivery

AI summary
A remote work support system that supports work using a remote operation robot in which a worker operates an operation robot and a work robot operates in a cooperative manner in response to an operation of the operation robot to perform work, the system includes: a sound collector that collects sounds generated during the work performed by the work robot; a sound generator that generates sounds to allow the worker who operates the operation robot to listen to the sounds; and a control device that extracts a sound having a specific frequency range from the sounds collected by the sound collector and causes the sound generator to output the extracted sound, in which the control device is capable of determining the specific frequency range.
