From Washington, D.C., NewsRx journalists report that a patent application by the inventors LAI, Qinwei (Zhuhai, Guangdong, CN); WANG, Yuelin (Zhuhai, Guangdong, CN); XU, Yimian (Zhuhai, Guangdong, CN), filed on November 24, 2020, was made available online on February 8, 2024. No assignee for this patent application has been made. News editors obtained the following quote from the background information supplied by the inventors: “Existing cleaning robots plan maps and navigate by means of inertial navigation, light detection and ranging or cameras. When using a cleaning robot, a user can see division of cleaning areas from a mobile device in real time. However, the cleaning areas are randomly divided into a plurality of areas only according to their coordinate information, instead of room units. Area division is mainly used for coverage planning, but at present, it’s still impossible to mark the information of an uncleaned area in advance on a map constructed in real time by means of a visual technology, resulting in ineffective division of rooms. “In the prior art, in the patent for invention with the application number of 2015100760659 filed by LG Electronics Inc. in China on Feb. 12, 2015, a pure-image visual means is used to identify positions of doors and shapes of door frames, so as to distinguish rooms. However, the requirement for positions where a robot acquires images is relatively strict, and the robot is required to acquire images repeatedly at multiple angles, such that the predetermined accuracy is not easy to achieve during identifying the positions of the doors.”
