Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous mobile robots often fail to detect homing signals from charging stations due to distant or obstructed locations, leading to manual intervention and poor user experience.
Innovation Solution
The method involves determining an optimal point on the boundary of an effective region to move towards, ensuring the robot navigates towards an open area where signal detection is more probable, using a processor-controlled apparatus with sensors to avoid obstacles and confined regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the autonomous mobile robot uses conventional signal reception method, then the robot can be charged when near the charging station, but the robot cannot detect the signal when far from or obstructed from the charging station
Solution Approach 1:
The robot performs preliminary actions by determining an effective region and optimal point before attempting signal reception. The robot proactively navigates to positions with higher signal detection probability rather than passively waiting for signal detection, thereby improving reliability in distant or obstructed locations.
Solution Approach 2:
The patent introduces an intermediary approach by using effective region determination and optimal point calculation as intermediate steps between the robot's current position and the charging station. This intermediary methodology enables the robot to systematically improve its signal detection probability through structured navigation.
2Ease of operation
If the robot manually places near the charging station, then the robot can be recharged, but the operation becomes complex and user experience deteriorates
Solution Approach 1:
The robot performs self-service by autonomously determining its effective region, calculating optimal points, and navigating to positions with higher signal detection probability. This self-service capability eliminates the need for manual user intervention to place the robot near the charging station, thereby improving ease of operation despite the increased internal system complexity.
3Area of stationary object
If the robot expands the effective region radius, then the signal detection coverage increases, but the navigation time to optimal point increases
Solution Approach 1:
The patent applies partial action by using a fixed-radius effective region that provides sufficient coverage without excessive expansion. This balanced approach ensures the robot achieves adequate signal detection coverage while minimizing navigation time to the optimal point, avoiding the time loss that would result from overly large effective regions.

AI summary
An autonomous mobile robot and a pile seeking method therefor, a control apparatus, and a smart cleaning system. The pile seeking method comprises: S1: using the center of an autonomous mobile robot to determine a first effective region; S2: determining an optimal point on the boundary of the first effective area, the remaining area at the optimal point being the largest, and the remaining area being defined as: the area of the remaining area of a second effective region that does not overlap with the first effective region, the second effective region being determined by taking the optimal point as the center; S3: controlling the center of the autonomous mobile robot to move to the optimal point; and S4: repeating steps S1-S3 until the autonomous mobile robot receives a signal from a charging pile for the first time. The pile seeking method can improve the possibility that a device automatically finds a pile signal by autonomous pile-seeking, ensuring the smart and reliability of the device, and improving the user experience.
