In other instances, well known process steps and/or structures have not been described in detail in order to not unnecessarily obscure the present invention.
- Generally, the disclosure relates to a modular robotic floor-cleaning system suitable for cleaning large spaces. Some embodiments provide a robotic floor-cleaning system that requires a minimal amount of maintenance. Some embodiments provide a robotic floor-cleaning system that can operate for extended periods of time and cover large amounts of surface area with a minimum of stoppages. Some embodiments provide a robotic floor-cleaning system that can effectively service large scale or commercial locations.
- Some embodiments provide a modular robotic floor-cleaning system. In some embodiments, a mobile cleaning robot has modules for each of its functions that collects or uses materials, substances, or resources. For example, a vacuuming module, a mopping module, a polishing module, and rechargeable battery module may be provided. In some embodiments, a separate base station stores new modules, so that when modules are expended, they may be exchanged for new modules. For example, once the vacuuming dustbin module is full, the robot returns to the base station and exchanges the full dustbin module for an empty dustbin module.
- In some embodiments, a floor-cleaning robot has modules for each of its functions that collect or consume resources. In some embodiments, the modules may be ejected and replaced as necessary. In some embodiments, a synchronized base station stores new modules and, in some embodiments, may also contain a repository for used modules. In some embodiments, the robot returns to the base station periodically, ejects expended modules, and loads new modules. In some embodiments, exchange of modules may be triggered by sensors that detect when a module has been expended. In some embodiments, exchange of modules may simply occur at predetermined intervals based on the run time of the system. In some embodiments, materials, substances, or resources of modules may be emptied or replenished after a particular amount of operational time or a particular distance travelled. In some embodiments, when the material, substance, or resource of a module must be emptied or replenished the robot may return to the base station or may switch from the functionality corresponding with the module to another functionality corresponding with another module. The system can thus continue working without waiting for human assistance in emptying, cleaning, or refilling modules.

FIG. 1A illustrates an example of an overhead view of a floor-cleaning robot 100. In the example shown, the robot has fourmodules 101. It should be noted that any number of modules may be provided without departing from the scope of the invention; the example shown is meant to be illustrative, rather than restrictive. Modules may have different functions related to the system capabilities. For example, a floor-cleaning robot may contain a dustbin module where vacuumed debris is stored, a cleaning fluid tank module where cleaning fluid for mopping the floor is stored, a water tank module where water for steaming the floor is stored, a polishing module where wax or another polishing agent for polishing a floor is stored, and a battery module where a battery for supplying power to the system is stored. Other types of modules may be provided without limitation; these examples are meant to be illustrative rather than restrictive. Modules may be devised to serve the particular capabilities of floor-cleaning system in question. -
FIG. 1B illustrates an example of abase station 102 storing extraunused modules 103. A base station is not limited in size and may contain any number of modules without limitation. - In some embodiments, the base station further comprises a repository for storing ejected/expended modules.
FIG. 2 illustrates an example of abase station 202. The base station comprises extraunused modules 203 and also has an area where used modules may be received. Used modules may be ejected into theempty slots 204. - In some embodiments, the floor-cleaning robot carries out operation as normal until it reaches any of a predetermined time limit, a predetermined stopping point, or a sensed state.
-
FIG. 3 illustrates an example of the process of exchanging modules during operation. In afirst step 300, the floor-cleaning robot operates using the modules positioned within the body of the device. In anext step 301, the system determines whether any module has been expended. In some embodiments, sensors positioned within modules detect when a module is expended. In some embodiments, sensors determine remaining capacity of modules. For example, in a vacuum dustbin module, a sensor may detect when the module is full. For example, in cleaning fluid tank modules, water tank modules, and polishing modules, a sensor may detect when the module is empty. For example, in a battery module, a voltmeter may detect when the battery is discharged. In some embodiments, a timer indicates that modules are expended after a predetermined amount of running time. In some embodiments, a user may provide input instructing the system that a module is expended. If no modules are expended, the device continues work normally. Upon detection that one or more modules has been expended, the method proceeds to anext step 302 to navigate to the base station. In some embodiments, the system may be provided with mapping technology by which the robot may localize itself and the base station within a map of the environment and navigate to the base station. In some embodiments, the robot uses a mapping system and/or odometry to navigate to the base station. In some embodiments, the floor-cleaning robot uses sensors to detect and navigate to the base station. The specific methods for navigating to the base station are not part of the scope of the invention, so a detailed description thereof is not provided. In anext step 303, the expended module or modules are ejected from the robot. Numerous methods for ejecting units from devices exist and are used across many fields; any available method may be used to eject the module from the robot. Specific methods for ejecting modules from the robot are not part of the scope of the invention, therefore a detailed description thereof is not provided. In anext step 304, a new module to replace the ejected module is loaded from the base station into the floor-cleaning robot. Numerous methods for loading units into devices exist and are used across many fields; any available method may be used to load the module into the robot. Specific methods for loading modules into the robot are not part of the scope of the invention, therefore a detailed description thereof is not provided. The system then continues operation as normal. -
FIG. 4 illustrates an example of the loading of a module from a base station into a robot. Therobot 400 contains threemodules 401 and has oneopen slot 402. The robot aligns theopen slot 402 with themodule 403 in thebase station 405 that is to be loaded into the open slot. Any method for aligning the robot with the target may be used. Methods for alignment are widely used in the field and are not part of the scope of the invention, therefore a detailed description thereof is not provided. Once the slot is correctly aligned, thenew module 403 may be loaded from the base station into the robot. The module is moved in adirection 404 into theslot 402. When the module is fully loaded into the slot, the robot may continue operation as normal. -
FIG. 5 illustrates an example of a robot including achassis 500, a set ofwheels 501, aprocessor 502, a plurality ofsensors 503, and acleaning assembly 504. - In some embodiments, a single base station may serve groups of floor-cleaning robots. In some embodiments, a base station containing modules for all the floor-cleaning robots in a group may be positioned in a central location where all the robots in the group may access it to load new modules as needed.
