Cleaning robot device and control method thereof

Cleaning robot device that switches cleaning modes based on the location of uncleaned areas

This technology is a cleaning robot device and control method that identifies uncleaned areas based on obstacle detection and environmental information, and dynamically updates and optimizes cleaning paths by switching between path, proximity, and remote modes depending on the location of those areas.

Conventional random, spiral, and zigzag methods struggle to secure efficient cleaning paths in indoor environments with many obstacles, leading to uncleaned areas, increased battery consumption, and delayed cleaning times.

This technology uses encoders, distance sensors, and contact sensors to identify obstacles and uncleaned areas. The control unit analyzes the relationship between obstacles and the location of uncleaned areas to select the appropriate cleaning mode in real time and update the path. Applicable to both residential and commercial cleaning robots, it eliminates uncleaned areas while reducing both cleaning time and battery consumption.

Key Features:

• A sensing unit that detects the surrounding environment using encoder, distance, and contact sensors
• A path movement step that applies movement signals for the cleaning robot to travel along its cleaning path
• A detection step that determines the presence of obstacles in the surrounding environment using the sensed information
• A configuration that updates the path by selecting between path, proximity, and remote modes based on the presence of obstacles and the location of uncleaned areas
