Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators face a heavy workload and time-consuming process when confirming the motion quality of a multi-axis robot, as they need to visually check various data such as movement, speed, acceleration, torque, and temperature across multiple axes, making it labor-intensive to determine if a taught program's motion is correct.
Innovation Solution
A robot simulation device with a motion simulation execution unit and a drive sound generation unit that records and simulates drive sounds based on actual robot data, allowing operators to assess motion quality by listening to drive sounds matching the robot's state, reducing the time and effort required for motion confirmation.

Engineering Contradiction Analysis
1Measurement precision
If operators visually check various data (movement, speed, acceleration, torque, temperature) for each axis of a multi-axis robot, then they can determine motion quality, but the process becomes time-consuming and labor-intensive
Solution Approach 1:
The patent replaces the visual inspection method (mechanical observation of data) with acoustic detection (listening to drive sounds). The drive sound generation unit creates sounds corresponding to robot drive sounds based on motion simulation results, and the sound output unit outputs these sounds. Operators can determine motion quality by listening to these synthesized drive sounds, which reduces the time and effort required compared to visually checking multiple data parameters across six axes.
2Measurement precision
If operators visually check various data for each of six axes, then they can assess robot motion, but the workload becomes heavy
Solution Approach 1:
The patent substitutes the complex visual data analysis process with a simpler acoustic perception task. Instead of requiring operators to systematically review multiple numerical parameters (movement, speed, acceleration, torque, temperature) for each of the six robot axes, the system synthesizes drive sounds that naturally encode this information. Operators can assess motion quality through auditory perception, which is cognitively less demanding and reduces operational workload while maintaining assessment accuracy.
3Measurement precision
If multiple parameters (speed, acceleration, jerk, torque, current, temperature) are monitored, then motion quality can be determined, but the complexity of the system increases
Solution Approach 1:
The patent merges multiple separate monitoring parameters (speed, acceleration, jerk, torque, current, temperature) into a unified acoustic output. The drive sound generation unit integrates all these motion simulation results and synthesizes them into a single drive sound signal that reflects the overall motion quality. This consolidation reduces system complexity by transforming multiple data streams into one composite acoustic indicator that operators can perceive and evaluate.
