Robot Interference Region Setting via 3D Camera Color Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for setting an interference region around a robot require manual input and preparation of 3D shape models, which are time-consuming and labor-intensive, and cannot handle complex or changing obstacle shapes effectively.
Innovation Solution
An interference region setting apparatus using a 3D camera to acquire camera images with distance and color information, generating a 3D map, and setting an interference region based on color-distinguishable point sequences, allowing automatic detection and exclusion of the robot's position from the map to define the interference zone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual input and 3D shape model preparation are used to set interference region, then interference region can be accurately defined, but the process requires a great deal of time and labor
Solution Approach 1:
The system enables automatic self-service by having the robot itself provide the data needed for interference region definition through its own movement and sensor outputs, eliminating the need for external manual measurement and 3D model preparation
Solution Approach 2:
The patent replaces manual mechanical measurement and 3D modeling processes with an automated sensor-based system that uses camera images and distance information to automatically generate the interference region
2Measurement precision
If manual input is used to set interference region, then interference region can be defined, but the process is labor-intensive
Solution Approach 1:
The robot performs self-service by automatically capturing images and providing distance information through its own sensors, eliminating the need for external operators to manually measure and define interference regions
Solution Approach 2:
The system creates a digital copy of the physical environment by capturing camera images and distance data, which are then processed to generate the interference region, replacing manual physical measurement with automated digital copying
3Measurement precision
If 3D shape model is prepared in advance, then interference region can be set, but complex or changing obstacle shapes cannot be handled effectively
Solution Approach 1:
The system transitions from static pre-prepared 3D models to dynamic real-time data collection, where the robot captures current environmental information through camera images and distance sensors, allowing adaptation to complex or changing obstacle shapes
Solution Approach 2:
The patent changes the approach from using fixed geometric models to using variable sensor data parameters (camera images, distance information) that can automatically adapt to any obstacle shape and configuration
