Swimming Pool Cleaning Robot Path Planning for Missed-Area Sweeping

Solution Overview

Problem

Current swimming pool cleaning robots employ parallel round-trip sweeping paths that result in repeated sweeping and prolonged cleaning times, reducing efficiency and coverage rate.

Innovation Solution

A method involving acquiring map information, planning an initial sweeping path based on set parameters, performing the initial sweep, and then conducting supplementary sweeps in missed areas to ensure complete coverage without redundancy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If parallel round-trip sweeping paths are employed to achieve high coverage traversal, then sweeping coverage rate is improved, but sweeping time is prolonged and redundant sweeping paths increase

Engineering Contradiction:

Improvesweeping coverage rateVSAvoidsweeping time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by performing a preliminary sweeping pass along the first sweeping path before conducting the supplementary sweeping pass. This initial pass covers the majority of the cleaning area, allowing the second pass to focus only on missed areas rather than re-sweeping already cleaned regions, thereby reducing redundant sweeping and total cleaning time

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent segments the sweeping operation into two distinct phases: a first sweeping pass along a primary path and a second supplementary sweeping pass targeting only missed areas. This segmentation allows each pass to have a specific focus, improving overall efficiency by avoiding redundant coverage while ensuring complete cleaning coverage

Inventive Principle:

Principle #1Segmentation

AI summary

The present application discloses a sweeping method of a swimming pool cleaning robot and a cleaning robot, the method including: acquiring map information about an area to be cleaned; planning a first sweeping path based on the map information, the first sweeping path meeting pre-set cleaning parameter requirements; controlling the cleaning robot to travel and perform a cleaning operation based on the first sweeping path; determining whether the cleaning operation is ended, and if so, controlling the cleaning robot to travel to a missed area so as to perform supplementary sweeping. This application can improve sweeping coverage rate and sweeping efficiency.
