Problems solved by technology

[0009] However, in Related Art 2, since the steep slope sensor is provided behind the auxiliary wheels, the auxiliary wheels may obstruct the sensing by the steep slope sensor or limit the sensing range of the steep slope sensor, and in particular, when the cleaner moves forward, Sensing via steep slope sensor does not work correctly
[0010] In addition, when the cleaner according to Related Art 2 is turned, the steep slope sensor may not be able to detect the steep slope until the auxiliary wheels reach and fall from the steep slope

Abstract

A robotic vacuum cleaner is provided. A robotic vacuum cleaner according to one embodiment of the present invention includes a body, a first rotating plate, a second rotating plate, a first wipe, a second wipe, a first support wheel, a second support wheel, and a first lower sensor. The first lower sensor senses a relative distance to the floor. A first lower sensor is disposed between the first support wheel and the second support wheel and is disposed farther away from the first and second rotating plates than the first and second wheels are away from the first and second rotating plates. According to an embodiment of the present invention, the robot cleaner may move while being supported by the first wipe, the second wipe, the first support wheel, and the second support wheel, and may easily avoid a steep slope where a floor accidentally descends.

Description

technical field [0001] The present disclosure relates to a robot cleaner (hereinafter referred to as a robot cleaner), and more particularly, to a robot cleaner including a pair of mops contacting a floor and rotating to wipe the floor, and a pair of wheels contacting the floor together with the mops. Background technique [0002] Robotic cleaners can include motors, various sensors, and artificial intelligence technology to clean areas that need to be cleaned while traveling autonomously. [0003] Robotic cleaners can be configured to vacuum dust, sweep dust, or mop the surface to be cleaned. [0004] As a related art document related to a robot cleaner, Korean Patent No. 1613446 (hereinafter referred to as “Related Art 1”) discloses “a robot cleaner and a method for operating a robot cleaner”. A robot cleaner disclosed in Related Art 1 includes a main body, a driver, a first rotating member, and a second rotating member. In addition, the robot cleaner disclosed in Relate...
