Robot Docking Boundary Guidance for Faster Charging Return
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for guiding outdoor robots, such as intelligent lawn mowers, to charging stations are inefficient, as they rely on random searches for boundary lines, leading to prolonged times for the robots to find and dock with the charging stations.
Innovation Solution
A method and device that control a self-moving device to move close to a docking boundary and sense boundary line signals, allowing the device to efficiently navigate to the charging station by following the boundary line signal until successful docking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the intelligent lawn mower searches for the boundary line according to random directions, then the lawn mower can eventually find the boundary line, but it takes a long time to find the boundary line
Solution Approach 1:
The patent applies preliminary action by pre-establishing a boundary line around the charging station that emits electromagnetic signals. Instead of random searching, the lawn mower is guided along this pre-prepared path, significantly reducing the time to find the boundary line and improving regression efficiency.
2Reliability
If the boundary line is laid out around the grass, then the lawn mower can follow the boundary line to the charging station, but the time to find the boundary line is prolonged due to random direction searching
Solution Approach 1:
The patent implements feedback by using electromagnetic signal sensors on the lawn mower to detect the boundary line's electromagnetic signals. The sensor provides continuous feedback about signal strength, allowing the lawn mower to adjust its position and follow the boundary line accurately to the charging station.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach significantly reduces the time for the self-moving device to find the boundary line, thereby improving the regression efficiency and enabling faster and more reliable charging operations.
Implementation Method 1
the boundary line can be a magnetic guideline that emits electromagnetic signals to the outside, the electromagnetic signal sensor of the intelligent lawn mower makes the boundary line longitudinally at the center of the intelligent lawn mower through the induced electromagnetic signal strength

AI summary
A method for docking a self-moving device to a charging station includes controlling the self-moving device to move relative to a docking boundary using a radio detection device, the radio detection device including a positioning base station and a positioning tag. The method includes judging whether the self-moving device senses a signal from a boundary line, and then taking certain steps depending on whether the boundary line signal was sensed. Related docking devices, self-moving devices, and storage media are also disclosed.
