Definitions
- the invention relates to the regular cleaning of a household.
- the invention relates to cleaning the household using an autonomous household robot.
- a household robot is set up to move autonomously in a household and to clean the floor.
- an environment map can be created, which in particular reflects a floor plan of the household. For example, sections of the household can be marked for deep cleaning or to be exempted from a cleaning run.
- the household robot is then usually controlled to clean the household on the basis of the map of the area, for example always on weekdays. If necessary, an additional cleaning run can be triggered manually.
- a robot is set up to move around in a household and perform a cleaning function.
- the household is divided into several areas, with cleaning frequencies assigned to the areas.
- a method for controlling the robot includes controlling a cleaning of each area depending on the cleaning frequency assigned to it.
- a user can individually determine for different areas how often the area is to be cleaned in each case.
- the individual Rich areas can be kept clean without requiring a sensor to determine different levels of contamination. Areas that are subject to heavier or more regular soiling can be cleaned more frequently than areas that are seldom soiled.
- the areas are each related and preferably the entire household can be disjunctively subdivided into areas. By specifying different cleaning frequencies, the areas can be cleaned individually on a regular basis. In particular, improved time-based cleaning can be implemented, with different areas being cleaned repeatedly at intervals of different lengths.
- a cleaning frequency comprises a multiple of a predetermined time interval.
- the multiple can in particular be an integer.
- the predetermined time interval can be given in minutes or hours, for example, and is either fixed or selectable by a user. Exemplary time intervals include six hours, twelve hours, and twenty-four hours. Shorter or longer time intervals are also conceivable.
- cleaning runs of the areas can be carried out in a grid, in which the cleaning of areas to be cleaned with different frequency can be combined. A person in the household can thereby be less disturbed, while at the same time the household can be automatically kept clean to an improved extent.
- the household can include several rooms and an area can affect one room in particular.
- a room of the household is identified and designated as an area. This process can take place in particular as part of a mapping of the household by the robot.
- the mapping can be done in a separate mapping run or during household cleaning, for example based on a SLAM (Simultaneous Localization and Mapping) algorithm.
- the room can thus be recognized, for example, on the basis of walls and a passageway or a door.
- a room divided off by means of a shelf can also be identified as a room.
- a user can fine-tune a detected area so that the area is improved to match a room or corresponding section of the household. can speak.
- the user can also create an area manually, whereby a room can be divided into several areas.
- a certain area can be divided and formed areas can be merged together if they are adjacent to each other. It is preferred that the ranges are disjoint from each other, but in one embodiment two ranges may be allowed to overlap.
- a type of room is recognized, it being possible for a cleaning frequency associated with the type of room to be suggested.
- the type of room can in particular reflect its usual or preferred use and can include, for example, a living room, a bedroom, a kitchen, a bathroom, a children's room, a baby room, a study, a sports room, a music room or a storage room.
- the type of a room can be recognized by a section or a location of the room in relation to neighboring rooms or in relation to the household.
- the type of room can also be determined on the basis of a piece of furniture known in the room, which can include, for example, a dining table, a work table, a bed, an instrument or sports equipment.
- a designation can be proposed for a recognized room, which can preferably be understandable and descriptive for an operator.
- the household can be completely divided into sections and each section can be assigned a unique name. The person can adapt a suggestion, accept it or replace it with an individual entry.
- a cleaning intensity is recorded for each area, it being possible for the cleaning of an area to be controlled with the associated cleaning intensity.
- a cleaning intensity can also be assigned to the type of room, which can be suggested for adoption. A user can accept the suggested cleaning intensity or replace it with an individual specification. It has been shown that in most cases a distinction between approx. three different cleaning intensities is sufficient.
- a cleaning intensity of zero is preferably not provided.
- the cleaning intensity can indicate how a cleaning device of the robot is operated during cleaning.
- the cleaning device can include a suction unit and the cleaning intensity can indicate how strongly a fan of the suction unit is activated.
- the cleaning process performed by the robot includes mechanical floor processing, for example by moving a damp cloth over the floor, then, for example, a contact pressure or a movement speed can be controlled.
- the driving speed of the robot can be reduced in order to increase the intensity of cleaning. In this way, both a cleaning frequency and a cleaning intensity can be set individually for an area. A combination of these two variables can provide sufficient flexibility to keep the area clean with relatively little expenditure of energy or time.
- an opposite change in cleaning frequency and cleaning intensity can be offered. For example, a user can decide to carry out cleaning more often and therefore less intensively than initially specified. Conversely, he can also opt for less frequent and therefore more intensive cleaning.
- areas to be cleaned are determined, which are to be cleaned simultaneously with regard to their cleaning frequencies. Areas to be cleaned at the same time can nominally have the same start time due to the cleaning frequency assigned to them and are preferably cleaned within a coherent cleaning run. Although the areas are actually cleaned sequentially by the robot, their cleaning is usually associated with the same time interval. If the time interval is, for example, three hours and the first area is to be cleaned every six hours and the second every nine hours, a simultaneous cleaning of both areas can be planned every eighteen hours in this sense.
- the cleaning process of the areas can be interrupted by a charging process.
- the cleaning of the specific areas can be interrupted by charging the energy store of the robot in such a way that during charging each of the specific areas is either completely cleaned or completely uncleaned.
- charging can preferably be controlled whenever the robot has finished cleaning a first area and has not yet started cleaning a subsequent second area. This can prevent a partially cleaned area from being re-contaminated by members of the household, for example.
- this area can also be divided into two sub-areas, which are then either completely cleaned or completely uncleaned while the robot recharges its energy storage device.
- An amount of energy can be determined for the specific areas, which is required for their cleaning.
- the charging can be planned with respect to the determined amounts of energy and a state of charge of an energy store of the robot. In this way, it can be predicted with a good degree of certainty which areas can be cleaned in a joint cleaning run and between which processes a charging process should be inserted.
- a sequence in which the individual areas are processed can be adapted in such a way that the energy store is better utilized. Scheduling can be done before a cleaning run begins, during the cleaning run, or during a charging process. In this case, it is preferable for a predetermined safety reserve to be planned in order to prevent the robot from having to leave an area partially cleaned behind or even stopping with an empty energy store.
- an energy consumption of a cleaning device of the robot can be considered.
- one for the movement the energy required for movement of the robot must be taken into account.
- both amounts of energy can be expressed per distance traveled by the robot.
- a combined energy consumption per distance traveled during cleaning can also be specified. This amount of energy can depend on a driving speed and/or a cleaning intensity. An amount of energy to be expended can thus easily be determined for the area whose size is known.
- areas to which the same cleaning intensities are assigned are cleaned as continuously as possible.
- the cleaning of areas with the same cleaning intensities is preferably not interrupted by charging. An acoustic load caused by the cleaning process can be reduced as a result.
- Charging is preferably planned in such a way that at the start of a charging process there is still a predetermined amount of energy in the energy store. This amount of energy can be used as collateral to ensure the robot returns to a charging station. This certainty can be increased with increasing age of the robot or the energy store in order to depict an aging effect. This can prevent the energy store from being exhausted at an unfavorable point in time.
- a device for controlling a robot is set up to move the robot in a household and to carry out a cleaning function.
- the household is divided into several areas and cleaning frequencies are assigned to the areas.
- the device is preferably set up to control cleaning of each area depending on the cleaning frequency assigned to it.
- the device can include a processing device that is set up to carry out a method described herein in whole or in part.
- the processing device preferably includes a programmable microcomputer or microcontroller, and the method is more preferably in the form of a computer program product with program code means.
- the computer program product can also be stored on a computer-readable data carrier be. Additional features or advantages of the method can be transferred to the device and vice versa.
- a household robot comprises a control device as described herein.
- FIG. 1 shows a household robot with a control device
- FIG. 2 shows a flow chart of a method for controlling a household robot
- Figure 3 illustrates a floor plan of an exemplary household.
- FIG. 1 shows a household robot 100 with a control device 105.
- the household robot 100 is set up to move autonomously in a household 110 and to carry out a predetermined cleaning activity.
- the cleaning function includes vacuum cleaning.
- the robot 100 usually includes a drive 115, an energy store 120, a cleaning device 125 and a processing device 130.
- the drive 115 is presently realized by two individually controllable wheels.
- An electric motor can be attached to each wheel.
- the electric motors can be fed from the energy store 120, which is preferably formed out as a chargeable electrical energy store 120.
- the cleaning device 125 comprises a suction unit, which usually comprises a suction mouth, a dust filter and a blower.
- the blower can also be operated using energy from the energy store 120 .
- Processing device 130 preferably controls the interaction between the movement of robot 100 by means of drive 115 and the execution of a cleaning function by means of cleaning device 125.
- a data memory 135 is preferably provided, in which a map of the surroundings of the person who is or may be is stored.
- One or more sensors 140 are provided for scanning an environment of the robot 100 .
- a position of the robot 100 in the household 110 can be determined based on readings of the sensors 140 .
- the scans can be used as a basis for creating or updating the map of the surroundings in the data memory 135 .
- control device 105 is installed on board the home robot 100 .
- part of the control device 105 can also be provided externally, for example the data memory 135 and/or the processing device 130.
- Information between the control device 105 and the household robot 100 can then be transmitted using a preferably wireless interface.
- the robot 100 be set up to clean different areas of the household 110 with respectively assigned cleaning frequencies and/or cleaning intensities.
- the determinations required for this can be carried out by means of the processing device 130 or also by means of another control device, the results of which are then transmitted to the control device 105 .
- FIG. 2 shows a flow chart of a method 200 for controlling a household robot 100.
- a map of the surroundings of the household 110 can be created.
- the map of the environment can be created by the robot 100 as it drives through the household 110, or it can come from an external source. For example, a user can provide information to provide the environment map.
- areas within the household 110 can be determined.
- the household 110 can be divided or segmented into areas.
- an area can correspond in particular to a room in the household 110 .
- a type of room can be determined automatically, for example based on furniture found in the room.
- a name can be assigned to the area.
- a suggestion can be made based on the determined type of room, which a user can accept or change.
- cleaning frequencies for the areas can be recorded and assigned to the areas.
- a cleaning frequency is preferably assigned individually to each area.
- a suggestion for a possible cleaning frequency can be provided based on a specific type of room. A user can accept this suggestion or specify a different value.
- cleaning intensities can be recorded and assigned to the individual areas. Again, a suggested cleaning intensity can be provided based on a specific type of room. A user can accept such a suggestion or enter it manually. Finally, the entered or specified information can be verified and, if necessary, changed. For example, cleaning frequencies or cleaning intensities in different areas can be better coordinated.
- a cleaning trip can be planned.
- Cleaning trips usually begin at integral multiples of a predetermined time frame, which can be six hours, for example.
- cleaning trips can be started at 6 a.m., 12 p.m., 6 p.m. and 10 p.m.
- An area that is scheduled to be cleaned every twelve hours then has a cleaning frequency of two, and another region that is scheduled to be cleaned every eighteen hours has a cleaning frequency of three.
- those areas can be specified which are to be cleaned at this point in time.
- An amount of energy required to clean each of the designated areas can then be determined. If a sum of the determined amounts of energy exceeds an amount of energy taken up in the energy store 120, the cleaning run can be subdivided once or several times in a step 230. Between Charging of the energy store 120 can be planned for the individual cleaning trips.
- Each cleaning run includes at least one area that is completely cleaned in it. Only partial cleaning of an area during a cleaning run is preferably avoided. Areas can be assigned to cleaning trips in such a way that the amount of energy available in the energy store 120 is utilized as well as possible. A predetermined reserve that should remain in the energy store 120 can be taken into account in this determination. In addition, the areas can be assigned to cleaning trips such that a cleaning trip has as few different cleaning intensities as possible. Areas with the same cleaning intensities are preferably cleaned one after the other.
- a cleaning run over the assigned areas can be controlled. If all areas have been cleaned, then in a step 240 charging of the energy store 120 can be controlled.
- the household robot 100 can in particular drive to a predetermined charging station, where optionally collected dirt can also be disposed of.
- step 235 If it is determined in step 235 that an area included in the current cleaning trip that has not yet been cleaned can no longer be cleaned completely due to a development in the amount of energy stored in energy store 120, charging can take place before the cleaning of this area begins and remaining areas that still have to be cleaned can be redistributed to cleaning runs.
- FIG. 3 shows an exemplary household 110 in the form of a floor plan.
- the household 110 includes a number of areas 305-350, each containing a room.
- the table gives an example of the assignment of names, types, frequencies and cleaning intensities to areas 305-350:
- rooms 325, 330 and 345 are to be cleaned at the same time, i.e. in the same cleaning run. However, since the rooms 325, 330 and 345 are relatively large, only two of them can be cleaned in a continuous cleaning run before the energy storage device 120 of the household robot 100 has to be recharged.
- the cleaning intensities of rooms 325 and 330 are the same, only the cleaning intensity of room 345 differs, so that the cleaning run is divided and rooms 325 and 330 are cleaned before the robot 100 recharges the energy storage device 120 .
- Room 345 is only cleaned afterwards and can be combined with the cleaning of rooms 315 and 350 in a joint cleaning cycle in order to avoid delays in the cleaning of rooms 315 and 350 due to their cleaning frequency. Since the cleaning intensity of room 345 differs from the cleaning intensities of rooms 315 and 350, rooms 315 and 350 are preferably cleaned together and room 345 is cleaned either before or after rooms 315 and 350.
