A cleaning robot includes a chassis, a cleaning device, a moving device, and a control system. The control system is configured to perform functions: capturing an image in front of a cleaning robot by a camera; comparing the image with a number of reference images to determine whether the image is the same as one of the reference images; storing a position of the cleaning robot and the image when the image is the same as one of the reference images; adjusting the path of the cleaning robot to stop the cleaning robot from cleaning the object; and emitting an alarm.
Description
- This present application is a divisional application of U.S. patent application, entitled “OBJECT SEARCHING SYSTEM, OBJECT SEARCHING METHOD, AND CLEANING ROBOT”, with application Ser. No. 13/207,679, filed on Aug. 11, 2011, which claims foreign priority based on Taiwanese Patent application No. 100118565, filed in Taiwan on May 27, 2011. The contents of the above-referenced applications are hereby incorporated by reference.
- The present disclosure relates to a cleaning robot, particularly to a cleaning robot including an object searching system and an object searching method.
- Many cleaning robots can sweep the room according to commands preset by a user. However, the cleaning robot may not be able to find a non-trash object when the cleaning robot is cleaning the room.
- Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
-
FIG. 1 is a schematic diagram of an exemplary embodiment of a cleaning robot. -
FIG. 2 is a block diagram of the cleaning robot ofFIG. 1 , wherein the cleaning robot includes an object searching system. -
FIG. 3 is a block diagram of an exemplary embodiment of the object searching system ofFIG. 2 . -
FIG. 4 is a flowchart of an exemplary embodiment of an object searching method. - The disclosure, including the accompanying drawings, is illustrated by way of examples and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
- Referring to
FIGS. 1 and 2 , an exemplary embodiment of acleaning robot 1 includes achassis 10, acontrol system 11, acleaning device 12, amoving device 15, abox 16, acamera 18, anobject searching system 19, and a locatingdevice 13. - The
chassis 10 is to cover thecontrol system 11, thecleaning device 12, themoving device 15, and thebox 16. Thecleaning device 12 may be a brush for cleaning the floor. The movingdevice 15 may include a motor, and wheels driven by the motor to move thecleaning robot 1. Thecontrol system 11 is used to set a path and time, and controls thecleaning device 12 and themoving device 15 according to the path and the time. Thebox 16 is used to store dirt. - The
camera 18 is mounted on thechassis 10 to capture an image in front of thecleaning robot 1. The locatingdevice 13 tracks a location of thecleaning robot 1. In the embodiment, the moving motions of thecleaning robot 1 can be regarded as how thecleaning robot 1 arrives at the present location from a starting point. For example, thecleaning robot 1 first goes one meter forward, then turns left and goes one meter forward, and at last, turns left and goes two meters forward. At this condition, a present location of thecleaning robot 1 can be regarded as “go one meter forward, turn left and go one meter forward, turn left and go two meters forward”. - Referring to
FIG. 3 , theobject searching system 19 includes aprocessing unit 100, and astorage unit 110. Thestorage unit 110 includes animage storing module 190, acomparison module 192, aninformation storing module 195, anadjustment module 196, and aninforming module 198, which may include computer code to be executed by theprocessing unit 100. - The
image storing module 190 stores a plurality of images of different objects. Each object corresponds to a plurality of images shot from different angles. The images are regarded as reference images. The different objects are regarded as important objects. Of course, users can add more images to theimage storage module 190 or delete some images stored in theimage storing module 190. - The
comparison module 192 compares the image captured by thecamera 18 with the reference images stored in theimage storing module 190 to determine whether the image captured by thecamera 18 is the same as one of the reference images stored in theimage storing module 190. - If the image captured by the
camera 18 is the same as one of the reference images stored in theimage storing module 190, theinformation storing module 195 stores a position where the locatingdevice 13 tracks at this time and the image captured by thecamera 18. - In addition, if the image captured by the
camera 18 is the same as one of the reference images stored in theimage storing module 190, theadjustment module 196 adjusts the path of thecleaning robot 1 to stop thecleaning robot 1 from cleaning the object. Moreover, theinforming module 198 informs the user, such as by emitting an alarm. In the embodiment, theinforming module 198 may include a light-emitting diode and/or a buzzer. The user can check the position and the image stored in theinformation storing module 195 to find out the object. - If the user is not at home when the
informing module 198 informs the user, the user can check the information stored in theinformation storing module 195 to determine whether thecleaning robot 1 has found an important object during the cleaning of the room after the user comes back. If thecleaning robot 1 has found an important object, the user can check the position and the image stored in theinformation storing module 195 to find the important object. Moreover, thecleaning robot 1 further includes a button. When the button is pressed, thecontrol system 11 reads the position stored in theinformation storing module 195, and controls the movingdevice 15 to make thecleaning device 1 go to the position. As a result, the user can find the important object. - Referring to
FIG. 4 , an exemplary embodiment of an object searching method includes the following steps. - In step S1, a plurality of images of different objects are stored in the
image storing module 190. Each object corresponds to a plurality of images shot from different angles. - In step S2, the
camera 18 captures an image in front of thecleaning robot 1. - In step S3, the
comparison module 192 compares the image captured by thecamera 18 with the images stored in theimage storing module 190 to determine whether the image captured by thecamera 18 is the same as one of the images stored in theimage storing module 190. If the image captured by thecamera 18 is the same as one of the images stored in theimage storing module 190, it flows to step S4. If the image captured by thecamera 18 is not the same as any image stored in theimage storing module 190, it returns to step S2. - In step S4, the
information storing module 195 stores a position where the locatingdevice 13 is tracking at this moment and the image captured by thecamera 18. - In step S5, the
adjustment module 196 adjusts the path of thecleaning robot 1 to stop thecleaning robot 1 from cleaning the object. - In step S6, the
informing module 198 informs the user. - The foregoing description of the exemplary embodiments of the disclosure has been presented only for the purposes of illustration and description and is not intended to be exhaustive or to limit the disclosure to the precise forms disclosed. Many modifications and variations are possible in light of everything above. The embodiments were chosen and described in order to explain the principles of the disclosure and their practical application so as to enable others of ordinary skill in the art to utilize the disclosure and various embodiments and with various modifications as are suited to the particular use contemplated.
