METHODS FOR REPURPOSING TEMPORAL-SPATIAL INFORMATION COLLECTED BY SERVICE ROBOTS

FIELD OF INTEREST

[0001] The present inventive concepts relate to methods for repurposing temporal- spatial information collected by service robots.

BACKGROUND

[0002] Service robots have traditionally been tasked with doing the dull and dirty jobs in human facilities, such as homes, commercial and industrial buildings. However, that very action of performing the service creates a large fund of temporal-spatial information and knowledge about the facility in which the work is performed.

[0003] Previous service robots have ignored this large fund of information and knowledge as an asset, resulting in its waste.

SUMMARY OF INVENTION

[0004] According to one aspect of the invention, provided is a method of servicing a facility with at least one service robot that obtains temporal-spatial information. The method includes: navigating a robot through an environment using automatic self-control by the robot; sensing the temporal-spatial information while performing a primary service function; and storing the temporal-spatial information.

[0005] The method can further include communicating the temporal-spatial information via a wireless network to a control system.

[0006] The method can further include at least one other service robot accessing the temporal-spatial information from the control system via the wireless network.

[0007] The method can further include at least one other autonomous control system accessing the temporal-spatial information from the control system.

[0008] The method can further include the service robot directly communicating the temporal-spatial information via a wireless network to at least one other service robot.

[0009] The method can further include the service robot performing a secondary service using the temporal-spatial information.

[0010] The method can further include the service robot analyzing the temporal- spatial information to improve the effectiveness and efficiency of the primary service that originally generated the temporal-spatial information.

[0011] The method can further include creating a three dimensional (3D) model of the environment using the temporal-spatial information.

[0012] The method can further include creating virtual tours from the 3D model.

[0013] The method can further include porting the 3D model of the environment to another system.

[0014] The method can further include recognizing and classifying objects in the environment using the temporal-spatial information.

[0015] The method can further include generating a catalog of objects and using the catalog to subsequently locate selected objects in the environment.

[0016] The at least one service robot can be a robotic vacuum cleaner.

[0017] In accordance with another aspect of the invention, provided is a service robotic system. The service robot includes: a platform supporting a servicing subsystem; a navigation controller coupled to a drive mechanism and configured to navigate the platform through an environment; one or more sensors configured to sense collect temporal-spatial information while performing a primary service; and a storage media on which the temporal- spatial information is stored.

[0018] The system can further include a communication module configured to communicate the temporal-spatial information via a wireless network to a control system.

[0019] At least one other service robot can be configured to access the temporal - spatial information from the control system via the wireless network.

[0020] The system can further include a communication module configured to directly communicate the temporal-spatial information via a wireless network to at least one other service robot.

[0021] The service robot can be configured to perform a secondary service using the temporal-spatial information.

[0022] The service robot can be further configured to analyze the temporal-spatial information to improve the effectiveness and efficiency of the primary service that originally generated the temporal-spatial information.

[0023] The service robot can be further configured to create a three dimensional (3D) model of the environment using the temporal-spatial information.

[0024] The service robot can be further configured to recognize and classify objects in the environment using the temporal-spatial information.

[0025] The service robot can be further configured to generate a catalog of objects and to use the catalog to subsequently locate selected objects in the environment.

[0026] The service robot can be a robotic vacuum cleaner.

[0027] The system can further include at least one other autonomous control system configured to access the temporal-spatial information from the control system.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT [0033] Hereinafter, aspects of the present invention will be described by explaining illustrative embodiments in accordance therewith, with reference to the attached drawings. While describing these embodiments, detailed descriptions of well-known items, functions, or configurations are typically omitted for conciseness.

[0034] It will be understood that, although the terms first, second, etc. are be used herein to describe various elements, these elements should not be limited by these terms.

These terms are used to distinguish one element from another, but not to imply a required sequence of elements. For example, a first element can be termed a second element, and, similarly, a second element can be termed a first element, without departing from the scope of the present invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

[0035] It will be understood that when an element is referred to as being "on" or

"connected" or "coupled" to another element, it can be directly on or connected or coupled to the other element or intervening elements can be present. In contrast, when an element is referred to as being "directly on" or "directly connected" or "directly coupled" to another element, there are no intervening elements present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., "between" versus "directly between," "adjacent" versus "directly adjacent," etc.).

[0036] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms "a," "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises," "comprising," "includes" and/or "including," when used herein, specify the presence of stated features, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and/or groups thereof.

[0037] Spatially relative terms, such as "beneath," "below," "lower," "above," "upper" and the like may be used to describe an element and/or feature's relationship to another element(s) and/or feature(s) as, for example, illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use and/or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" and/or "beneath" other elements or features would then be oriented "above" the other elements or features. The device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0038] FIG. 1 is a flowchart 100 of an embodiment of a method for controlling a service robot using temporal-spatial information. In this embodiment the service robot is a cleaning robot, such as a robotic vacuum.

[0039] In step 102, the robot performs the service functions, such as vacuuming. In step 104 the robot collects temporal-spatial information while performing the service, e.g., as in step 102. In step 106 the temporal-spatial information is made available for other uses by other applications and/or robots - and/ or by the robot collecting the information. For example, in some implementations robots can work in teams and communicate such information back and forth via wireless networks. One robot could scout locations requiring service and note whether they are occupied and communicate the need and availability to another one or more robots - as an example.

[0040] The robots can include sensors to collect such temporal-spatial information, such as those generally known in the art. For example, sensors could include acoustic, motion detection, camera or other sensors.

[0041] As will be appreciated by those skilled in the art, a service robot (e.g., vacuum) includes a memory for storing instructions and data, and a processor for executing the instructions. Thus, the methods discussed above can be programmed into the service robot for execution to accomplish the functions disclosed herein.

[0042] Also, while the service robot was indicated as a robotic cleaner in this embodiment, those skilled in the art will appreciate that methods in accordance with the present invention could be applied to any number of service robots, and could implement any number and types of sensors.

[0043] In another embodiment the service robot would communicate the temporal- spatial data collected to a server or other computer, which would include the processor for manipulating the data and a storage system for storing the data. This server could be used to communicate the re-purposed information back to the original robot, or to other robots or servers which can make use of it.

[0044] As an example, the following description will describe a potential application for this method and illustrate its operation. A service robot is used to clean the floors in an industrial facility. It is programmed to follow a path which carries it throughout the facility. A temperature sensor is mounted to the robot, and as it is doing its primary function, it is also recording the temperature of the environment at intervals along the programmed path. The temperature-location data is transmitted to the facility heating system, which maps the position data from the robot to its control zones. It thus can use the recorded temperatures to adjust the heating output of the different zones.

[0045] FIG. 2 shows an embodiment of a service robot 200 including an upward facing sensor 210. The sensor 210 can be used to determine characteristics of the environment in the area. The determination may be based on other perceptual techniques such as acoustics, motion detection, etc. In still other embodiments, the determination method may be based on a combination thereof.

[0046] FIG. 3 shows an embodiment of a service robot 300 with multiple sensors 310 that allow the robot 300 to determine the characteristics of the environment in the area.

[0047] FIG. 4 shows an embodiment of a system for repurposing temporal-spatial information from a robot. Component 400 is the service robot, component 410 is the sensor mounted to the robot, component 420 is the localization system of the robot which provides the location, or spatial information, component 430 is the robot executive controller which manages the autonomous operation of the robot, component 440 is a communication means to transmit the spatial-temporal information to the data storage system 450. The data storage system 450 stores the temporal-spatial information, and any meta-data required for its interpretation. Component 460 is a transformation system that adapts the information to a form usable by a requesting application.

[0048] While reference has been made to using wireless networks, in various embodiments any of a variety of data communication schemes can be used, such as wired, (batch) wireless, networked, Point-to-point, and so on.

[0049] While the foregoing has described what are considered to be the best mode and/or other preferred embodiments, it is understood that various modifications can be made therein and that the invention or inventions may be implemented in various forms and embodiments, and that they may be applied in numerous applications, only some of which have been described herein.
