An autonomous floor cleaner or floor cleaning robot can include an autonomously moveable housing and a drive system for autonomously moving the autonomously moveable housing over a surface to be cleaned based on inputs from a controller. A brush chamber, a debris receptacle, and a supply tank can be formed as a unitary assembly removable from the autonomously moveable housing.

A robot floor cleaning system features a mobile floor cleaning robot and an evacuation station. The robot includes: a chassis with at least one drive wheel operable to propel the robot across a floor surface; a cleaning bin disposed within the robot and arranged to receive debris ingested by the robot during cleaning; and a robot vacuum configured to pull debris into the cleaning bin from an opening on an underside of the robot. The evacuation station is configured to evacuate debris from the cleaning bin of the robot, and includes: a housing defining a platform arranged to receive the cleaning robot in a position in which the opening on the underside of the robot aligns with a suction opening defined in the platform; and an evacuation vacuum in fluid communication with the suction opening and operable to draw air into the evacuation station housing through the suction opening.

A pouch designed for administration of an active ingredient in the oral cavity is disclosed, the pouch containing a matrix composition including a combination of nicotine and a water-soluble composition.

A vacuum cleaner that can perform cleaning after grasping a shape of a cleaning area, and perform cleaning more efficiently. The vacuum cleaner includes a main casing, a driving wheel, a travel control part, a cleaning unit, a periphery detection sensor, and a map generation part. The driving wheel enables the main casing to travel. The travel control part controls driving of the driving wheel to make the main casing travel autonomously. The cleaning unit performs cleaning. The periphery detection sensor detects a shape of a periphery area of the main casing. The travel control part controls the driving of the driving wheel to make the main casing perform a specified initial operation in a specified range, whereby the periphery detection sensor performs scanning. The map generation part generates a primary map of the cleaning area on the basis of the shape of the scanned periphery area.

A cleaning robot includes a propulsion mechanism to propel the robot on a floor, a robotic arm with a gripper at its distal end, and a plurality of different cleaning tools, each cleaning tool including a handle that is configured to be grasped by the gripper. At least one of a plurality of receptacles is configured to hold one of the cleaning tools. A controller is configured to autonomously operate the propulsion system to transport the robot to region to be cleaned, operate the robotic arm to bring the gripper to a receptacle that is holding a selected cleaning tool, operate the gripper to grasp a handle of the selected cleaning tool and to manipulate the cleaning tool when cleaning the region, and operate the robotic arm and the gripper to return the selected cleaning tool to its receptacle.

Systems and methods for a universal connection interface between a robot and a plurality of modular attachments are disclosed. Also disclosed are autonomous robotic system and devices comprising a control module in operative connection to a drive module and at least one task module, the drive module configured to move the system through a space as instructed by the control module, the at least one task module configured to perform a task or set of tasks as instructed by the control module. The robotic device also includes a data receiving unit. A command is given by the user to the robotic device to perform a function, and the device then transmits the data to the accessory task module through the data receiving unit. In one exemplary implementation, a robot may be assigned a plurality of different tasks to be accomplished by connecting to a plurality of different modular attachments to using a single universal connection interface. The robotic system and/or device can perform multiple cleaning or yard maintenance tasks.

An automatic cleaning device including a first light sensor and a controller is provided. The first light sensor is disposed at a side position of a device body. The controller is coupled to the first light sensor. When the controller performs an automatic charging operation, the controller controls the device body of the automatic cleaning device to move forward and determines whether the first light sensor senses a light signal emitted by a light emitter of the charging dock. When the first light sensor senses the light signal, the controller records a first time parameter, and when the first light sensor no longer senses the light signal, the controller records a second time parameter. The controller determines whether to execute a first return mode or a second return mode according to a first time difference between the first time parameter and the second time parameter. In addition, an automatic charging method is also provided.

A cleaner may include a main body configured to be ascendable and descendable with respect to a suspension assembly provided to absorb shocks applied to a wheel assembly, thereby enabling the suspension assembly to continuously absorb shocks even when the height of the main body is adjusted. The cleaner may further include a charging terminal configured to connect to an external docking device to charge the cleaner and provided on a bottom surface of the main body, a drive assembly including a wheel assembly to drive the main body, a height adjuster coupled to the main body to ascend or descend together with the main body and mounted to the drive assembly so as to be ascendable and descendable, and a controller to ascend the height adjuster and raise the main body when the main body is set to be docked with the docking device.

A debris monitoring system includes a receptacle, a first and a second emitter, and a first receiver. The receptacle defines an opening to receive debris into the receptacle. The first and second emitter are each arranged to emit a signal across at least a portion of the opening. The first receiver is proximate to the first emitter to receive reflections of the signal emitted by the first emitter, and the first receiver is disposed toward the opening to receive an unreflected portion of the signal emitted by the second emitter across at least a portion of the opening.

A mother-child robot cooperative work system and a work method thereof include a mother robot and a charging base0, in which the mother robot is provided with a control unit and a work unit. The system also includes child robot, communicatively coupled to the mother robot. The mother robot performs cleaning for a work area under the control of the control unit, and recognizes cleanable area and assisted cleaning area in a cleaning process. After cleaning work in the cleanable area is completed, the control unit in the mother robot controls the child robot to cooperatively complete the cleaning work in the assisted cleaning area. The mother robot is provided with a child robot pose sensing unit. The unit inputs child robot pose information to the control unit; and the control unit controls the child robot to act as indicated.
