Robot Interference Data Sharing Without Exposing 3D Models
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to enhance convenience while maintaining security when transmitting and storing data related to industrial robots, particularly sensitive three-dimensional data, which is often confidential and not suitable for cloud servers due to security concerns.
Innovation Solution
A robot data processing server equipped with a communication device to receive interference data associating teaching point candidates with interference results, indicating potential robot interactions with surrounding objects, and a storage device to store this data, allowing for secure and convenient data management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If three-dimensional data such as workshop or workpiece data is transmitted and stored in a cloud server, then convenience is improved through data sharing and processing, but security deteriorates due to exposure of highly confidential data
Solution Approach 1:
The patent extracts only the necessary interference determination results from the three-dimensional data, separating the confidential geometric information from the operational data that needs to be shared. By transmitting only the interference results rather than the complete three-dimensional data, the system achieves data sharing convenience while protecting the confidentiality of workshop and workpiece designs.
Solution Approach 2:
Instead of transmitting the original three-dimensional data, the patent creates and transmits a processed copy in the form of interference determination results. This copy contains the essential operational information needed for robot path planning while excluding the sensitive geometric details, thus resolving the contradiction between sharing convenience and security protection.
2Productivity
If three-dimensional data is transmitted to enable cloud processing, then productivity is improved through centralized data access, but loss of information increases due to potential data breaches
Solution Approach 1:
The patent extracts only the interference determination results from the complete three-dimensional data set. This extraction process retains the functional information necessary for robot operation optimization while removing the confidential geometric details, thereby enabling productivity improvement through cloud processing without risking information loss through data breaches.
Solution Approach 2:
The interference determination results serve as an intermediary data form between the original three-dimensional data and the robot control system. This intermediary layer enables centralized cloud processing and productivity improvement while acting as a protective barrier that prevents direct exposure of confidential three-dimensional data, thus avoiding information loss.
Data Source
AI summary
A server includes a communication device and a storage device. The communication device receives the interference data from the client device connected via the wide area network. The interference data is data which associates teaching point candidates indicating candidates for the teaching points of the industrial robot with interference results indicating whether or not the robot interferes with surrounding objects when the position and posture of the robot is aligned with the teaching point candidate. The storage device stores the interference data received by the communication device.
