Sweeping robot and walking control method for same

Abstract

The invention provides a sweeping robot and a walking control method for the same. The method comprises the following steps of: mounting a plane mirror on a wall of a room to be swept, wherein a vertical non-reflective surface is arranged in the center of the plane mirror; the normal direction of the non-reflective surface is the positive direction of an X axis; a horizontal direction parallel to the plane mirror is the direction of a Y axis; and the central point of the vertical non-reflective surface is the original point of the X axis and the Y axis; calibrating the walking direction of the sweeping robot and the position of the original point according to the change of reflected laser which is transmitted to the plane mirror by a laser transmitter and received by a photoelectric conversion receiving head; calculating the walking distance of the sweeping robot in the X and Y directions by using a control module of the sweeping robot and positioning the sweeping robot on an indoor ground; and according to the positioning in a walking process, recording swept areas and identifying un-swept areas to finish the full sweeping of the indoor ground. The sweeping robot and the walking control method can realize a high-efficiency cleaning task and have a low cost.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a cleaning robot and a walking control method of the cleaning robot. Background technique [0002] At present, fully automatic indoor cleaning robots have been widely promoted and used in the market. In order to control costs, most cleaning robots rely on infrared or ultrasonic probes to detect obstacles, identify distances, and then combine some algorithm programs to formulate indoor walking control strategies to basically cover the area to be cleaned. The biggest problem brought about by the method of the prior art is the low work efficiency, which is manifested by the fact that the cleaning robot walks seemingly irregularly. Usually, each area in the room will be cleaned repeatedly 4 to 5 times, and often individual areas are not cleaned once. clean up. Some cleaning robots use technologies such as high-precision GPRS global satellite positioning technology, laser ...

Problems solved by technology

The biggest problem brought about by the methods in the prior art is the low work efficiency, which is manifested by the fact that the cleaning robot walks seemingly irregularly. Usually, each area in the room will be cleaned repeatedly 4 to 5 times, and often individual areas are not cleaned once. clean up

Some cleaning robots use technologies such as high-precision GPRS global satellite positioning technology, laser projection combined with CCD digital photoelectric image sensor technology, and high-precision electronic compass. growth, the market's acceptance capacity is also greatly reduced
