Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for setting restricted regions for robot arms are complex and time-consuming, especially when determining the position and shape of prohibited areas, making efficient automation challenging.
Innovation Solution
A setting device and method that includes a display section for showing a restriction region setting image with input sections for selecting permitted or prohibited regions and inputting boundary information, and a processing section that acquires and sets the restriction region based on user input, allowing for easy and quick configuration of restricted areas for robot arms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a robot arm is used to perform automated operations, then productivity is improved, but the complexity of setting restricted regions increases
Solution Approach 1:
The system creates a virtual model (operation prohibited region) that copies and represents the physical restricted area in the robot's workspace. This virtual model allows the robot to understand and avoid restricted regions through software representation rather than physical barriers or complex mechanical constraints, thereby reducing setting complexity while maintaining productivity.
2Reliability
If the operation prohibited region is set to ensure safe robot operation, then reliability is improved, but the time required for setting increases
Solution Approach 1:
The system replaces complex manual measurement and physical marking processes with automated image processing and coordinate transformation algorithms. The operation prohibited region is defined through software-based coordinate systems and mathematical transformations of captured images, eliminating time-consuming manual setting operations while ensuring reliable safe operation through precise digital boundary definition.
3Ease of operation
If manual setting of the operation prohibited region is performed, then ease of operation is maintained, but productivity is reduced due to time consumption
Solution Approach 1:
The system enables self-service setting by automatically capturing images of the workspace, processing these images to identify restricted regions, and generating the operation prohibited region definition without requiring manual measurement or complex user input. The robot system itself performs the setting operation through automated image processing and coordinate transformation, greatly improving setting speed while maintaining ease of use through simple image capture and confirmation.

AI summary
A setting device includes a display section configured to display a restriction region setting image including a first input section for selecting and inputting either a restriction region of a permitted region where intrusion of a robot arm of a robot is permitted or a prohibited region where intrusion of the robot arm is prohibited and a second input section for inputting a boundary of the restriction region; an acquisition section configured to acquire setting information input and set in the first input section and the second input section; and a process section configured to set the restriction region for the robot arm based on the setting information acquired by the acquisition section.
