Cleaning Robot Light Detection for Restricted-Area Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning robots lack effective methods to determine the direction of light sources and navigate around restricted areas, leading to inefficient movement and potential entry into prohibited zones.
Innovation Solution
The implementation of a quasi-omnidirectional light detector and a directional light detector system, where the quasi-omnidirectional detector spins to determine the spin direction based on light beam detection, and the cleaning robot moves accordingly until the directional detector confirms the light source, allowing it to avoid restricted areas and efficiently navigate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a non-omnidirectional light detector is used to determine light source direction, then the cleaning robot can navigate away from restricted areas, but the device complexity increases due to the spinning mechanism and multiple detectors required
Solution Approach 1:
The light detection function is divided into two specialized detectors: a non-omnidirectional light detector for determining light source direction through spinning, and an omnidirectional light detector for monitoring light beam presence. This segmentation allows each detector to be optimized for its specific function, improving overall navigation reliability while managing complexity through functional specialization.
Solution Approach 2:
The non-omnidirectional light detector is designed to spin dynamically to scan the environment and determine the direction of light sources. This dynamic spinning mechanism enables the detector to cover all directions sequentially, providing reliable directional information without requiring a complex static omnidirectional detector array.
2Measurement precision
If the quasi-omnidirectional light detector spins to determine spin direction, then the cleaning robot can accurately navigate, but the loss of time increases due to the spinning and angle estimation process
Solution Approach 1:
The system performs preliminary spinning and angle estimation using the non-omnidirectional light detector before final navigation. By pre-determining the light source direction and spin angle in advance, the robot can then execute efficient navigation movements without repeated scanning, reducing overall navigation time while maintaining directional precision.
Solution Approach 2:
The omnidirectional light detector provides continuous feedback on light beam presence during navigation. This feedback allows the system to verify whether the estimated direction is correct and make real-time adjustments, ensuring measurement precision while minimizing unnecessary spinning time through adaptive navigation.

AI summary
