Method and apparatus for detecing unknown obstacle and medium and electronic device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous mobile robots face challenges in detecting unknown obstacles within a short distance range, leading to potential collisions due to limited recognition capabilities of their sensors, particularly cameras, which can only accurately detect obstacles within a specific range.
Innovation Solution
The method involves moving the autonomous mobile robot away from the unknown obstacle to a position where the sensor, such as a camera, can effectively detect it, ensuring the detection distance exceeds the sensor's limitations, and then navigating based on the detection result to avoid collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the autonomous mobile robot uses a sensor or camera to detect obstacles, then it can identify ground conditions and navigate, but it cannot accurately detect unknown obstacles within a short distance range due to limited sensor recognition capabilities
Solution Approach 1:
Instead of moving the sensor to detect close obstacles, the patent inverts the approach by moving the robot body away from the obstacle to increase the detection distance. The robot receives a first instruction to move away from the obstacle to a first position, ensuring the distance is within the sensor's effective detection range, then detects the obstacle and navigates based on the detection result.
2Reliability
If the autonomous mobile robot moves closer to unknown obstacles for detection, then it can potentially identify them, but it risks collision due to insufficient detection distance
Solution Approach 1:
The patent resolves this contradiction by inverting the conventional approach: instead of moving the sensor toward the obstacle to improve detection, it moves the robot body away from the obstacle to achieve both safety and effective detection. The processing device generates a first movement instruction to relocate the robot to a position where the obstacle is within detectable range but at a safe distance.
3Adaptability or versatility
If the autonomous mobile robot uses fixed sensor detection range, then the system structure is simple, but it cannot adapt to unknown obstacles at varying distances
Solution Approach 1:
The patent applies dynamics by making the detection distance adjustable through robot movement rather than relying on fixed sensor ranges. The processing device dynamically generates movement instructions to position the robot at an appropriate distance from unknown obstacles, allowing the detection system to adapt to varying obstacle distances without changing the sensor hardware.

AI summary
A method and apparatus for detecting an unknown obstacle, and a medium and an electronic device. During a moving process of a autonomous mobile robot, if an obstacle of an unknown type is detected within a distance from which detection cannot be performed, the autonomous mobile robot moves away from the obstacle to be within an effective detection distance, and then navigation is performed by means of an effective detection result.
