Self-Moving Device Reachability Scanning for Blocked Destinations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-mobile devices face challenges in responding timely to environmental changes, such as closed doors, leading to errors in path planning and inability to continue tasks effectively.
Innovation Solution
The method involves scanning the target position to determine its reachability, sending prompt information to a remote terminal, and resuming movement if the position becomes reachable, using scanning sensors to update environment information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the self-mobile device relies on historical map information for path planning, then the device can operate autonomously without real-time updates, but the device cannot respond timely to environmental changes such as closed doors or moved obstacles
Solution Approach 1:
The system performs preliminary path planning based on historical map information before execution. When the device encounters an unreachable destination, it preliminarily scans the target position to detect environmental changes before attempting alternative paths, allowing proactive adaptation rather than reactive correction
Solution Approach 2:
The system implements feedback by continuously monitoring whether the destination is reachable during path execution. When unreachable state is detected, the system triggers a scanning operation to obtain updated environmental information, then feeds this information back to the path planning module to generate new paths, creating a closed-loop control system that adapts to real-time changes
2Reliability
If the device continuously scans the environment to detect changes, then the device can respond timely to environmental changes, but the device consumes more energy and operates more slowly
Solution Approach 1:
Instead of continuously scanning the entire environment, the system performs partial scanning only when needed - specifically when the destination is detected as unreachable. The scanning is focused on the target position and relevant areas rather than comprehensive environmental monitoring, reducing energy consumption while maintaining detection effectiveness
Solution Approach 2:
The scanning operation is performed periodically or event-driven rather than continuously. The system scans the target position at intervals or when triggered by specific conditions (unreachable destination detection), allowing the device to conserve energy during normal operation while maintaining the capability to detect environmental changes when necessary

AI summary
A method and apparatus for causing a device to advance to a designated location, and a self-moving device. The method comprises: when it is detected that a designated location is in an unreachable state, scanning a target location, so as to obtain a scanning result (101); and if the scanning result indicates that the designated location is currently in a reachable state, continuing to advance to the designated location (102).
