Disclosed is a robot cleaner including a body having a module location portion, a traveling module for moving the body, and a sliding module having a body location portion detachably coupled to the module location portion, the sliding module being configured to slide along a floor when the body is moved. A mop fixing unit for fixing a replaceable mop is provided between the module location portion and the body location portion.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for automatically cleaning a portion of an environment. One of the methods includes detecting, by an automated cleaning system, movement within a physical environment; determining, by the automated cleaning system and using data that represents the movement, that one or more threshold criteria for cleaning at least a portion of the physical environment are satisfied; and in response to determining that the one or more threshold criteria for cleaning at least the portion of the physical environment are satisfied, sending, by the automated cleaning system, an instruction to a device in the physical environment to cause the device to initiate a cleaning process of at least the portion of the physical environment.

A cleaner includes a first cleaning module including a left spin mop and a right spin mop that come into contact with a floor while rotating in a clockwise direction or in a counterclockwise direction when viewed from an upper side, a second cleaning module that comes into contact with the floor at a position spaced apart from the left spin mop and the right spin mop in a forward-and-backward direction, a body supported by the first cleaning module and the second cleaning module, and a water supply module that supplies water to the first cleaning module. A water tank is disposed inside the body. Water supplied by the water supply module reaches the first cleaning module before reaching the floor.

A cleaner includes a first cleaning module including a left spin mop and a right spin mop configured to contact the floor while rotating in a clockwise direction or in a counterclockwise direction when viewed from an upper side, a second cleaning module configured to contact the floor in front of the first cleaning module, and a body supported by the first cleaning module and the second cleaning module. A point on the bottom surface of the left spin mop that receives the largest frictional force from the floor is located on a left-front side of the rotation center of the left spin mop, and a point on the bottom surface of the right spin mop that receives the largest frictional force from the floor is located on a right-front side of the rotation center of the right spin mop.

A robot cleaner includes a rolling cleaning module including a rolling member configured to rotate clockwise or counterclockwise when viewed from a left side while in contact with a floor, a sensor unit, and a controller. The controller is configured to determine a change in position of the robot cleaner and a change in load current of a motor connected to the rolling member based on data detected by the sensor unit, and determine that a specific area of the floor is a contaminated area when there is a change in the position and a change in the load current.

A moving robot is provided. The moving robot includes: a main body forming the exterior appearance; a moving means for moving the main body; a bumper configured to protrude on the outer perimeter of the main body; impact sensors placed at an angle on the main body to sense the movement of the bumper; and pressure parts formed in a bent shape at the end of the impact sensors.

A robot may identify a human located proximate to the robot in a physical environment based on sensor data captured from one or more sensors on the robot. A trajectory of the human through space may be predicted. When the predicted trajectory of the human intersects with a current path of the robot, an updated path to a destination location in the environment may be determined so as to avoid a collision between the robot and the human along the predicted trajectory. The robot may then move along the determined path.

A cleaning robot may determine a three-dimensional model of a physical environment based on data collected from one or more sensors. The cleaning robot may then identify a surface within the physical environment to clean. Having identified that surface, the robot may autonomously navigate to a location proximate to the surface, position an ultraviolet light source in proximity to the surface, and activate the ultraviolet light source for a period of time.

A model of a physical environment may be determined based at least in part on sensor data collected by one or more sensors at a robot. The model may include a plurality of constraints and a plurality of data values. A trajectory through the physical environment may be determined for an ultraviolet end effector coupled with the robot to clean one or more surfaces in the physical environment. The ultraviolet end effector may include one or more ultraviolet light sources. The ultraviolet end effector may be moved along the trajectory.

A washing apparatus washes a cleaner having a mop unit formed at a lower portion thereof. The washing apparatus includes a tray configured to form a space to receive the cleaner and washing water. A washing unit is disposed at a lower portion of the inside of the tray in contact with the mop unit. The washing unit includes a first spinning mop protrusion line configured to protrude upwardly, an upper end of the first spinning mop protrusion line being inclined downwardly in a first direction.
