Shared Map Updating for Multi-Machine Obstacle Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In scenarios where multiple autonomous working machines operate in a shared monitoring area, the lack of shared map information leads to safety concerns and decreased efficiency due to potential obstacles not being accurately accounted for, as machines may not detect or update information about objects in their environment effectively.
Innovation Solution
An information processing device that collects monitoring information from multiple units, detects objects, updates map information based on object positions, and provides this information to working machines to ensure safe route planning, using first and second map information to differentiate between likely and temporary object presence, and includes features for object attribute evaluation, notification, and potential removal instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each working machine manages its own map information independently, then device complexity is reduced and ease of operation is improved, but safety decreases due to inability to detect objects detected by other machines
Solution Approach 1:
The patent merges map information from multiple working machines into a shared map information management system. The map information management unit consolidates monitoring information from multiple machines, integrates object detection data, and provides unified map information to all machines, enabling collective awareness of the work area while maintaining individual machine independence.
Solution Approach 2:
The map information management unit acts as an intermediary between multiple working machines. It receives monitoring information from various machines, processes and integrates the data, then distributes the consolidated map information back to the machines, enabling indirect information sharing without direct machine-to-machine communication complexity.
2Measurement precision
If map information is updated frequently to ensure accuracy, then measurement precision of object positions is improved, but loss of time increases due to continuous updates and route recalculations
Solution Approach 1:
The system performs preliminary actions by continuously collecting monitoring information from multiple working machines and pre-processing this data to update map information proactively. This allows the map to be updated with object positions before they become critical obstacles, reducing the need for emergency route recalculations and minimizing time loss.
Solution Approach 2:
The map information management unit implements feedback mechanisms by continuously receiving monitoring information from working machines, comparing it with existing map data, and updating the map information accordingly. This feedback loop ensures measurement precision is maintained while optimizing update frequency to avoid unnecessary time consumption.
3Reliability
If shared map information is implemented across multiple machines, then safety improves through better obstacle awareness, but device complexity increases due to information integration requirements
Solution Approach 1:
The map information management unit serves multiple functions: it collects monitoring information from various working machines, integrates object detection data, maintains updated map information, and distributes this information back to all machines. This multi-functional approach consolidates complexity into a single universal system rather than requiring complex peer-to-peer integration between machines.
4Reliability
If working machines bypass all detected objects to ensure safety, then safety is improved, but productivity decreases due to unnecessary route deviations
Solution Approach 1:
The system applies local quality by differentiating between permanent obstacles and temporary objects in the map information. The map information management unit identifies object characteristics and marks them with different attributes, allowing working machines to bypass only necessary obstacles while proceeding directly through areas with temporary or removable objects, thus maintaining safety while improving productivity.
