Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measurement systems using sensors installed in robots face challenges in synchronizing the operation of sensors with robots, particularly when the combination of sensor and robot is arbitrarily selected, leading to difficulties in improving measurement accuracy.
Innovation Solution
A measurement system equipped with a synchronous processing unit that acquires a robot drive signal and generates a trigger signal for the sensor to start a measurement operation, allowing for synchronization without the need to change the robot's motor drive signal program.

Engineering Contradiction Analysis
1Reliability
If a synchronization signal is incorporated into a motor drive signal output to a motor of the robot, then synchronization between sensor and robot is achieved, but a program for generating the motor drive signal on the robot side needs to be changed
Solution Approach 1:
The invention introduces a synchronous processing unit as an intermediary component that receives the robot drive signal and generates the trigger signal for the sensor. This mediator approach allows synchronization without requiring modifications to the robot control program, as the synchronous processing unit independently processes the drive signal to create synchronized sensor triggering.
Solution Approach 2:
The system separates the synchronization function into a distinct synchronous processing unit that is independent from both the robot control unit and the sensor control unit. This segmentation allows each unit to operate independently while achieving coordination, avoiding the need to modify existing control programs in either the robot or sensor units.
2Adaptability or versatility
If the combination of sensor and robot is arbitrarily selected, then versatility of measurement system is improved, but ease of building synchronized measurement system deteriorates
Solution Approach 1:
The synchronous processing unit is designed as a universal component that can work with any robot drive signal and generate appropriate trigger signals for various sensor types. This multi-functional design enables arbitrary sensor-robot combinations while maintaining synchronized operation, as the synchronous processing unit adapts to different combinations without requiring custom integration work.

AI summary
In measurements using a sensor installed in the tip of a robot arm, it is necessary to synchronize a measurement operations of the sensor with the operations of the robot in order to improve the accuracy of the measurement. However, in the cases where the combination of a sensor and a robot is arbitrarily selected, it is not easy to build a measurement system for synchronizing the operations of the sensor with that of the robot. A measurement system configured to perform a measurement using a sensor installed in a robot, includes a synchronous processing unit configured to acquire a robot drive signal transmitted from a robot control unit configured to control the robot to the robot, and generate a trigger signal for triggering the sensor to start a measurement operation when the robot drive signal includes a command signal for the robot to start driving.
