Robot Obstacle Search Using 3D Scanning for Path Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot systems require manual input of obstacle information, which is time-consuming and prone to errors, and necessitate re-scanning of spaces when the operating range changes, leading to potential interference with obstacles.
Innovation Solution
A non-contact three-dimensional measuring unit attached to the robot automatically searches for obstacles by dividing the search space into cube regions, allowing efficient and accurate detection of obstacles without blind spots, eliminating the need for manual input and reducing human error.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual input of obstacle information is used, then obstacle data can be entered into the system, but inputting effort increases and errors occur when information is input erroneously
Solution Approach 1:
The patent replaces manual mechanical input methods with an automated optical measurement system. A three-dimensional measuring device captures obstacle information automatically, substituting the manual data entry process with non-contact optical measurement, thereby eliminating input errors and reducing time consumption
Solution Approach 2:
The system performs self-measurement of the work space including obstacles. The three-dimensional measuring device autonomously captures and records obstacle information without requiring external manual input, enabling the system to serve itself in acquiring necessary spatial data
2Adaptability or versatility
If the operating range of the robot changes, then the robot can access new areas, but spaces must be searched again including areas that have been searched before
Solution Approach 1:
The system implements feedback by storing previously measured spatial data and using it to inform future search operations. When the robot's operating range changes, the system references existing three-dimensional measurement data to identify already-searched areas, avoiding redundant scanning and reducing overall search time
Solution Approach 2:
The system performs preliminary three-dimensional measurement of the work space in advance. By capturing complete spatial information before operation begins, the system prepares a comprehensive map that can be referenced during subsequent operations, eliminating the need to re-search areas when the operating range changes

Function Achieved in This Case
This solution enables automatic generation of operation paths that avoid obstacles, reducing human error and allowing for efficient and accurate path creation, even when the search space changes, by outputting search results directly to the operation path generation device.
