Description

Autonomous vacuum cleaner, control method of autonomous vacuum cleaner, and program

The present invention relates to an autonomous traveling type vacuum cleaner that autonomously travels and cleans a predetermined space, a control method of the autonomous traveling type vacuum cleaner, and a program.

Conventionally, when the autonomous traveling type vacuum cleaner (also called a robot vacuum cleaner) travels while sucking dust on the floor surface, the floor surface may be lifted upward and affect the floor surface. Therefore, an autonomous traveling type vacuum cleaner that reduces the influence on the floor surface has been proposed (see, for example, Patent Document 1).

The autonomous traveling type vacuum cleaner disclosed in Patent Document 1 travels along the tatami mats when traveling on the tatami mats. As a result, the influence of the autonomous traveling vacuum cleaner on the tatami mats can be reduced.

However, for example, when cleaning a carpet, if the autonomous traveling type vacuum cleaner travels in various directions to clean the carpet, the fur of the carpet (hereinafter, also referred to as carpet grain) may not be aligned and may be disturbed. As a result, the cleaning performance (in other words, the appearance of the carpet) deteriorates.

Therefore, for example, the X-axis and the Y-axis, which are axes orthogonal to each other, are predetermined on the map 300. That is, the area information includes, for example, two XY coordinates (X, Y). Specifically, when the area information 173 includes, for example, (X, Y) = (x1, y1) and (X, Y) = (x2, y2), the carpet area is (X, Y) =. It is indicated by a rectangular region having two vertices (x1, y1) and (X, Y) = (x2, y2).

[Processing procedure]
Next, the processing procedure of the autonomous traveling type vacuum cleaner 100 of the present embodiment will be described with reference to FIGS. 7 to 10.

FIG. 7 is a flowchart showing a processing procedure of the autonomous traveling type vacuum cleaner 100 according to the present embodiment. FIG. 8 is a diagram showing an example of the map 300 corresponding to the cleaning information 171. Specifically, FIG. 8 shows the carpet area 401 shown in the XY coordinates and the cleaning information 171 on the map 300 held by the autonomous traveling vacuum cleaner 100 shown in FIG. 5 (for example, stored in the storage unit 170). Is a diagram schematically showing.

As shown in FIG. 7, the autonomous traveling type vacuum cleaner 100 first starts cleaning from an arbitrary position on the map 300.

The position of the autonomous traveling vacuum cleaner 100 is represented by (X, Y) coordinates represented by pixel values or distances when the upper left corner of the map 300 is the origin of the coordinates, for example, as shown in FIG. Suppose it is done. That is, the position at the start of cleaning of the autonomous traveling type vacuum cleaner 100 starts from an arbitrary position set by the user. Then, the autonomous traveling type vacuum cleaner 100 sequentially cleans a predetermined space for each area from the cleaning start position set by the user. As a result, the autonomous traveling type vacuum cleaner 100 travels over the entire cleaning area (here, the travelable area 302 shown in FIG. 8) for cleaning.

Next, the cleaning information acquisition unit 130 acquires the cleaning information 171 stored in the storage unit 170 in advance and the map information (step S101).

Note that the map information may be acquired via communication from an external communication device. Further, the map information may be generated by the autonomous traveling type vacuum cleaner 100 by the mounted SLAM.

Further, in step S101, the plan generation unit 150 calculates the travel route of the autonomous traveling type vacuum cleaner 100 based on the acquired map information.

Next, the self-position detection unit 140 detects (calculates) the self-position by using the sensor data acquired by the sensor data acquisition unit 110 and the map information acquired by the map information acquisition unit 120 (step S102). That is, the self-position detection unit 140 detects the position of the autonomous traveling vacuum cleaner 100 in a predetermined space (map 300). At this time, the self-position detecting unit 140 repeatedly detects the self-position while the autonomous traveling type vacuum cleaner 100 is running, for example.

Next, the plan generation unit 150 uses the self-position calculated in step S102, the map information, and the cleaning information 171 acquired in step S101 to determine whether the autonomous traveling type vacuum cleaner 100 is located in the carpet area. It is determined whether or not (step S103).

At this time, when it is determined that the autonomous traveling type vacuum cleaner 100 is located in the carpet area (Yes in step S103), the plan generation unit 150 sets the traveling pattern for the carpet area as the planning information (step S104). ). That is, when the plan generation unit 150 determines that the autonomous traveling type vacuum cleaner 100 is located in the carpet area based on the detected self-position, the plan generation unit 150 plans for the carpet area based on the cleaning information 171 and the map information. Generate information. Here, the traveling pattern for the carpet region is a traveling route of the autonomous traveling type vacuum cleaner 100 in the carpet region. Specifically, the autonomous traveling type vacuum cleaner 100 travels in a comb shape, for example, in the carpet region, and travels in a bow shape, for example, in a region other than the carpet region. The comb-shaped traveling refers to traveling when the traveling route of the outward route and the traveling route is the same when the autonomous traveling type vacuum cleaner 100 reciprocates. On the other hand, the bow-shaped traveling means traveling when the traveling routes of the outward route and the returning route are different when the autonomous traveling type vacuum cleaner 100 reciprocates.

That is, in step S104, the plan generation unit 150 recalculates the traveling route as the traveling pattern for the carpet area so that the autonomous traveling type vacuum cleaner 100 travels in a comb shape.

Here, the first example of the cleaning pattern of the autonomous traveling type vacuum cleaner 100 will be described with reference to FIGS. 9 and 10.

Note that FIG. 9 is a perspective view of the non-carpet region 400 shown with hatching when viewed from diagonally above. FIG. 10 is a diagram showing a first example of a cleaning pattern in a region (carpet region 401) where the carpet mesh of the autonomous traveling type vacuum cleaner 100 is aligned. Note that FIG. 10 is a perspective view of the carpet region 401 shown with hatching when viewed from diagonally above.

First, as shown in FIG. 9, the control unit 160 drives the drive unit 190 while driving the suction unit 180 to suck dust in the non-carpet region 400 determined by the plan generation unit 150, and autonomously travels. The mold vacuum cleaner 100 is run in a bow shape.

On the other hand, as shown in FIG. 10, the control unit 160 drives the suction unit 180 along the direction of the carpet mesh by driving the autonomous traveling type vacuum cleaner 100 in the region determined by the plan generation unit 150 to be the carpet region 401. The drive unit 190 is driven to run while sucking dust. The direction of the carpet mesh is the same as the direction in which the autonomous traveling type vacuum cleaner 100 travels when sucking, as shown in FIG.

At this time, the control unit 160 does not drive the suction unit 180 when the autonomous traveling type vacuum cleaner 100 is traveling in a direction different from the carpet stitch in the region determined by the plan generation unit 150 to be the carpet region 401. , Drive the drive unit 190 to drive the autonomous traveling type vacuum cleaner 100. The direction different from the above-mentioned carpet stitch is a direction different from the traveling direction (broken line arrow) of the autonomous traveling type vacuum cleaner 100 when sucking, as shown in FIG.

As described above, the autonomous traveling type vacuum cleaner 100 of the present embodiment has a first traveling mode showing a traveling pattern when traveling in the carpet region 401 and a non-carpet region 400 other than the carpet region 401. It has a second running mode that shows a running pattern. Then, the autonomous traveling type vacuum cleaner 100 switches the mode and travels based on the self-position, the map information, and the cleaning information 171 (more specifically, the area information 173 and the orientation information 174 shown in FIG. 6). To do. Specifically, for example, when the non-carpet area 400 is driven by the autonomous traveling type vacuum cleaner 100, the plan generation unit 150 generates the planning information for causing the autonomous traveling type vacuum cleaner 100 to travel in a bow shape. Here, the bow-shaped traveling means traveling in a zigzag manner and causing the autonomous traveling vacuum cleaner 100 to perform a suction operation when moving forward. On the other hand, when the carpet area 401 is driven by the autonomous traveling type vacuum cleaner 100, the plan generation unit 150 generates the planning information for the autonomous traveling type vacuum cleaner 100 to perform a comb-shaped traveling. Here, the comb-shaped traveling means that the autonomous traveling type vacuum cleaner 100 is operated by suction only in the same direction.

The type of running pattern is not limited to the above-mentioned bow-shaped running and comb-shaped running. For example, as a traveling pattern, the carpet region 401 may orbit a predetermined space so as to travel in only one direction according to the direction of the carpet mesh.

As described above, the autonomous traveling type vacuum cleaner 100 executes the cleaning operation in the cleaning pattern shown in the first example.

Generate information. Then, the plan generation unit 150 then generates plan information for traveling the reverse route in the same direction as the direction of the carpet. At this time, the plan generation unit 150 generates the plan information for causing the control unit 160 to control the drive unit 190, the suction unit 180, and the cleaning unit 200, together with the plan information for running the autonomous traveling type vacuum cleaner 100.

Then, the control unit 160 drives the drive unit 190 based on the plan information generated above. As a result, the autonomous traveling type vacuum cleaner 100 first travels on the first path 500 indicated by the solid line arrow in FIG. Next, the autonomous traveling type vacuum cleaner 100 is made to travel on the second path 501 indicated by the alternate long and short dash arrow in FIG. As a result, in all the carpet areas 401, the autonomous traveling type vacuum cleaner 100 is run and cleaned in the same direction as the direction of the carpet eyes, and as a result, the direction of the carpet eyes is changed in the carpet area 401. Can be aligned.

As described above, in the third example of the cleaning pattern, the plan generation unit 150 generates the plan information for determining the direction of the carpet grain and the reverse route traveling in the opposite direction in the carpet area 401.

Specifically, in step S108, the control unit 160 drives the drive unit 190 to move the autonomous traveling type vacuum cleaner 100 by a predetermined moving distance (for example, 30 cm) according to the traveling path. The predetermined moving distance may be arbitrarily determined in advance, and may be further stored in the storage unit 170.

Next, the plan generation unit 150 determines whether or not the cleaning in the predetermined area is completed (step S109). Specifically, the plan generation unit 150 determines whether or not the travel path calculated by the autonomous traveling type vacuum cleaner 100 has been completed. That is, it is determined whether or not the autonomous traveling type vacuum cleaner 100 has completed cleaning in the predetermined area.

Then, when the plan generation unit 150 determines that the cleaning in the predetermined area is not completed (No in step S109), the process returns to step S102 and the cleaning run in the predetermined space is continued.

On the other hand, when the plan generation unit 150 determines that the cleaning in the predetermined area is completed (Yes in step S109), the control unit 160 controls the drive unit 190 to a predetermined position such as a charger (not shown). , The autonomous traveling type vacuum cleaner 100 is moved to finish the cleaning.
