Description

Technical Field

[0001] The present invention relates to a pest control system for harmful birds and beasts.

Background Art

[0002] In recent years, damage to crops caused by harmful beasts such as deer and wild boars and harmful birds such as crows (hereinafter, these are collectively referred to as "harmful birds and beasts") has been serious. Therefore, measures such as capturing harmful birds and beasts with guns or traps, or surrounding the fields with protective nets or electric fences have been taken. However, with the aging of hunters, the number of captured harmful birds and beasts has tended to decrease. In addition, the protective net may be damaged by harmful birds and beasts, and the electric fence may malfunction due to electric leakage.

[0003] Also, as a countermeasure against harmful birds and beasts, a method of driving away harmful birds and beasts with sound is known. Patent Document 1 discloses an apparatus that emits distress calls, explosive sounds, etc. to suppress the flying-in of wild birds or drive away flying-in wild birds against harmful birds such as crows and sparrows.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, countermeasures against harmful birds and beasts such as distress calls and explosive sounds have a problem that the effect cannot be satisfactorily obtained because harmful birds and beasts quickly get used to them.

[0006] Therefore, a technical problem to be solved arises in order to provide a pest control system that can effectively drive away harmful birds and beasts, and an object of the present invention is to solve this problem.

Means for Solving the Problems

[0007] To achieve the above objectives, the present invention provides a pest control system for birds and animals that have entered or approached a field, comprising: an intrusion detection sensor arranged in or near the field to detect when a bird or animal has entered its detection range; a threatening robot that, upon receiving a detection signal from the intrusion detection sensor, performs a threatening action to intimidate the bird or animal within or near the detection range where the intrusion was detected; and a wound simulation robot that, upon receiving a detection signal from the intrusion detection sensor, performs a wound simulation action that mimics the wounding behavior of a bird or animal within or near the detection range where the intrusion was detected.

[0008] Furthermore, the pest bird and animal control system according to the present invention preferably includes a first intrusion detection sensor which is arranged in a plurality of locations within or near the field and detects when a pest bird or animal enters its detection range, and when the intimidation robot receives a detection signal from the first intrusion detection sensor, it travels to or near the detection range where the first intrusion detection sensor detected the intrusion of the pest bird or animal, based on the location information of the detection range where the first intrusion detection sensor detected the intrusion of the pest bird or animal, and performs the intimidation operation.

[0009] Furthermore, the pest bird and animal control system according to the present invention preferably comprises a second intrusion detection sensor which is arranged in a plurality within the field and detects when the pest bird or animal enters the detection range, and the injury simulation robot is positioned within the detection range of the second intrusion detection sensor when in standby mode, and when it receives a detection signal from the second intrusion detection sensor it performs the injury simulation operation within or near the detection range.

[0010] Furthermore, it is preferable that the pest bird and animal control system according to the present invention includes a camera for capturing images of the pest bird and animal, a position detection sensor for detecting the position of the pest bird and animal relative to the intimidation robot based on the images captured by the camera, and a control unit for controlling a driving unit that drives the intimidation robot to pursue and capture the pest bird and animal based on the position of the pest bird and animal detected by the position detection sensor. [Effects of the Invention]

[0011] According to this invention, in the detection area where harmful birds and animals are detected, a simulated injury robot can perform actions that mimic the actions of a threatening robot near a threatening robot, thereby causing the harmful birds and animals to perceive that the simulated injury robot has been attacked and injured by the threatening robot, and thus efficiently driving the harmful birds and animals out of the field.

[0013] Embodiments of the present invention will be described based on the drawings. In the following, when referring to the number of components, numerical values, amounts, ranges, etc., unless otherwise specified or limited to a specific number in principle, it is not limited to that specific number, and it may be more or less than the specific number. [[IDID=3]]

[0014] Also, when referring to the shape, positional relationship, etc. of components, etc., unless otherwise specified or it is considered otherwise in principle, it includes those substantially similar or analogous to the shape, etc.

[0015] Also, the drawings may be exaggerated, such as enlarging characteristic parts for easy understanding of the characteristics, and the dimensional ratios of components, etc. are not necessarily the same as the actual ones.

[0016] <First Embodiment> FIG. 1 is a schematic diagram showing a pest bird and animal control system 1 according to the first embodiment of the present invention. FIG. 2 is a block diagram of the pest bird and animal control system 1. The pest bird and animal control system 1 according to the present embodiment mainly drives away pest birds and animals 4 such as crows that have invaded a field 3 surrounded by a fence 2. The pest bird and animal control system 1 includes a sensor unit 10, a threatening robot 20, and an injury-simulating robot 30.

[0017] Five sensor units 10 are provided in a zigzag pattern within the field 3. The sensor unit 10 includes an infrared sensor 11 as an intrusion detection sensor capable of detecting pest birds and animals 4, a communication unit 12, and a control unit 13. The number of installed sensor units 10 may be 4 or less or 6 or more as long as the entire field 3 can be covered.

[0018] When the infrared sensor 11 detects the intrusion of pest birds and animals 4 into the detection range 11a, it outputs a detection signal. The detection ranges 11a of the five infrared sensors 11 are set so that there are no dead spots within the field 3.

[0019] The control unit 13 sends a detection signal indicating the intrusion of a harmful bird or animal 4 and location information of the detection range 11a where the harmful bird or animal 4 was detected to the deterrent robot 20 via the communication unit 12 and a network (not shown).

[0020] The deterrent robot 20 is a known dog-type robot or the like that can travel within the field 3. The deterrent robot 20 comprises a travel unit 21, a communication unit 22, a control unit 23, and a memory unit 24. When no harmful birds or animals 4 are detected, the deterrent robot 20 remains on standby in the first storage unit 40. When on standby, the deterrent robot 20 charges its battery 25 via the power supply unit 41 of the first storage unit 40.

[0021] The running section 21 consists of actuators for moving the limbs if the intimidation robot 20 is a quadruped robot, and caterpillar tracks that can support the dog-shaped model or the like if the intimidation robot 20 is a caterpillar robot with a dog-shaped model or the like mounted on it.

[0022] When the control unit 23 receives the detection signal from the infrared sensor 11 and the location information of the detection range 11a where the harmful bird or animal 4 was detected via the communication unit 22, it retrieves a movement route from the first storage unit 40 to the detection range 11a where the harmful bird or animal 4 was detected, which is stored in the memory unit 24, and drives the travel unit 21 along this movement route, causing the deterrent robot 20 to travel towards the detection range 11a of the sensor unit 10 that detected the harmful bird or animal 4 or to its vicinity. It is preferable that the path along which the deterrent robot 20 travels within the field 3 is prepared in advance.

[0023] The deterrent robot 20 is equipped with a speaker 26. When the deterrent robot 20 arrives at or near the detection range 11a of the infrared sensor 11 that has detected the harmful bird or animal 4, the speaker 26 emits a dog bark or the like to deter the harmful bird or animal 4. In other words, the deterrent robot 20 performs a deterrent action by emitting a bark to intimidate the harmful bird or animal 4.

[0024] The deterrent robot 20 is equipped with a camera 27 and a position detection sensor 28. When the deterrent robot 20 arrives at or near the detection range 11a of the infrared sensor 11 that has detected a harmful bird or animal 4, the camera 27 continuously or intermittently at predetermined intervals images the area around the deterrent robot 20. The position detection sensor 28 recognizes the harmful bird or animal 4 to be controlled from the images captured by the camera 27, and the control unit 23 drives the travel unit 21 so that the deterrent robot 20 tracks the harmful bird or animal 4. In other words, the deterrent robot 20 performs a deterrent action by chasing the harmful bird or animal 4.

[0025] When the position detection sensor 28 can no longer recognize the harmful bird or animal 4 in the image captured by the camera 27, the control unit 23 determines that the harmful bird or animal 4 has been driven away from the field 3, retrieves the movement route to the first hangar 40 that has been pre-stored in the memory unit 24, and drives the driving unit 21 along this movement route so that the intimidation robot 20 returns to the first hangar 40.

[0026] The injury simulation robot 30 comprises a travel unit 31, a communication unit 32, a control unit 33, and a memory unit 34. When no harmful birds or animals 4 are detected, the injury simulation robot 30 remains on standby in the second hangar 50. While on standby, the injury simulation robot 30 charges its battery 35 via the power supply unit 51 of the second hangar 50. Alternatively, the injury simulation robot 30 may be powered by a power cable installed in the second hangar 50 instead of being powered by the battery 35.

[0027] The second hangar 50 is equipped with an infrared sensor 52, which serves as an intrusion detection sensor to detect the approach of harmful birds and animals 4. When the infrared sensor 52 detects the intrusion of harmful birds and animals 4 into the detection range 52a set around the second hangar 50, it outputs a detection signal. The infrared sensor 52 may be replaced with other sensors if they can detect harmful birds and animals 4. When the infrared sensor 52 detects the approach of harmful birds and animals 4, the control unit 53 sends a detection signal to the injury simulation robot 30 via the communication unit 54 and a network (not shown) to inform it of the intrusion of harmful birds and animals 4.

[0028] As shown in Figure 3, it is preferable that multiple second storage units 50 are provided within the field 3 so that harmful birds and animals 4 can be driven away no matter where they fly into the field 3, and that the injury simulation robots 30 are stored in each of the second storage units 50. In the layout shown in Figure 3, the second storage units 50 are arranged with gaps between them at the four corners of the field 3 and in the center of the field 3. Reference numeral 55 denotes a lead connecting the injury simulation robot 30 and the second storage unit 50.

[0029] As shown in Figure 4, the injury simulation robot 30 is a robot modeled after a mallard duck. However, the model for the injury simulation robot 30 is not limited to mallards; it may also be a crow, starling, white wagtail, sparrow, or pigeon, etc.

[0030] The running section 31 comprises a pair of elliptical wheels 31a on the lower part of the main body 36 and a motor (not shown) that drives the wheels 31a. The motor drives the wheels 31a to rotate, causing the injury simulation robot 30 to move up and down. Leg parts 31b, which resemble the feet of a mallard duck, are attached to the outer surface of the wheels 31a.

[0031] As shown in Figures 4 and 5, the body 36 of the injury simulation robot 30 comprises a torso 36a, a head 36b, a wing section 36c, and a tail feather section 36d. The size of the body 36 is set to be close to the size of a real mallard duck; for example, the total length from the head 36b to the tail feather section 36d is set to 35-65 cm, and the wingspan with the wing section 36c extended is set to 65-90 cm.

[0032] A hole 36aa is formed in the body section 36a. By releasing smoke or the like from a smoke-generating device (not shown) installed in the hole 36aa in conjunction with the flapping of the wings 36c and tail feathers 36d, the injured robot 30 can simulate being shot. In addition, a speaker 36ab built into the body section 36a emits sounds such as the squawking of a mallard duck, gunshots, dog barks, or attack sounds.

[0033] The wing sections 36c are provided on the left and right sides of the fuselage section 36a. The wing sections 36c are made of multiple frames 36ca connected via hinges or other joints (not shown) in a foldable manner. The frames 36ca are made of, for example, metal, resin, or wood. The joints have an opening limit so as not to open beyond a predetermined angle, and are provided with biasing means to bias the joints to maintain the open state. The leading edge feathers 36cb, which mimic the primary flight feathers, the intermediate feathers 36cc, which mimic the secondary flight feathers, and the basal edge feathers 36cd, which mimic the tertiary flight feathers, are made of, for example, metal, resin, or wood.

[0034] The tail feather section 36d is connected to the body section 36a via a joint (not shown), and the tail feather section 36d is configured to flap up and down via an actuator (not shown).

[0035] The injury simulation robot 30 is equipped with a mechanism 37 for folding the wing section 36c and a mechanism 38 for flapping the wing section 36c.

[0036] As shown in Figures 6(a) and (b), the mechanism 37 for folding the wing portion 36c comprises a wire 37b stretched from the tip to the base of the wing portion 36c, passing through a ring 37a provided at the joint, and an actuator (ACTR) 37c connected to the base end of the wire 37b. When the actuator 37c winds up the wire 37b and applies a tensile force to the wire 37b, the frame 36ca is folded against the biasing force of the biasing means that opens the frame 36ca around the joint, as shown in Figures 6(c) and (d). When the actuator 37c releases the tensile force applied to the wire 37b, the wing portion 36c is unfolded by the biasing means provided at the joint.

[0037] As shown in Figures 7(a) and (b), the mechanism 38 for flapping the wing section 36c comprises a frame 38a provided on the fuselage section 36a and supporting one of the pivot points P of a pair of skeletal structures 36ca that mimic the humerus, a rotatable gear 38b (not shown), and a connecting member 38c that connects the base end of the pair of skeletal structures 36ca to the gear 38b. The tips of the pair of skeletal structures 36ca are connected via joints 36ce to a single skeletal structure 36ca that mimics the forearm bone.

[0038] As shown in Figure 7(a), when the gear 38b rotates clockwise on the plane of Figure 7, the connecting member 38c pulls the base end of the frame 36ca laterally, causing the tip end of the frame 36ca to collapse. Also, as shown in Figure 7(b), when the gear 38b rotates counterclockwise on the plane of Figure 7, the connecting member 38c pulls the base end of the frame 36ca downward, causing the tip end of the frame 36ca to stand up. By repeating these actions, the injury simulation robot 30 can perform movements that mimic the flapping of a mallard's wings.

[0039] When the control unit 33 receives a detection signal from the infrared sensor 52 that has detected a harmful bird or animal 4 via the communication unit 32, the injury simulation robot 30 exits the second hangar 50 and performs an action that mimics the injury simulation behavior of a mallard duck for a predetermined time (for example, 20 seconds).

[0040] Here, "injury simulation" refers to actions performed by wild birds and animals to simulate being injured and unable to fly, and the actions performed by the injury simulation robot 30 that mimic injury simulation include actions that mimic the injury simulation of a mallard duck, such as flapping and opening / closing of the wings 36c and tail feathers 36d, rotating the wheels 31a, and emitting screaming sounds from the speaker 36ab.

[0041] The injury-simulating robot 30 performs actions that mimic the injury-simulating behavior of a mallard duck near the intimidating robot 20, which performs intimidating actions, thereby making the pest animal 4 believe that the injury-simulating robot 30 has been attacked and injured by the intimidating robot 20. In addition, by emitting dog barks or similar sounds from the speaker 26 of the intimidating robot 20, the pest animal 4 can also be made to believe that the injury-simulating robot 30 is being attacked by the intimidating robot 20.

[0042] Subsequently, the lead 55 connected to the injury simulation robot 30 is retracted, causing the injury simulation robot 30 to return to the second hangar 50.

[0043] Furthermore, when the injury simulation robot 30 leaves the second hangar 50, it is conceivable that the system be configured to use springs or the like installed inside the second hangar 50 to propel the injury simulation robot 30 out of the second hangar 50.

[0044] Alternatively, instead of detecting harmful birds and animals 4 using the infrared sensor 52 of the second hangar 50, the system may be configured to send the location information of the detection range 11a of the sensor unit 10 that detected the harmful birds and animals 4 to the injury simulation robot 30, and to release the injury simulation robot 30 located in the vicinity of the detection range 11a of the second hangar 50 that detected the harmful birds and animals 4 from the second hangar 50.

[0045] Furthermore, the intrusion detection sensor may be any other sensor that can detect harmful birds and animals 4, instead of the infrared sensors 11 and 52.

[0046] In this way, the pest control system 1 according to this embodiment is a pest control system 1 that drives away pest birds and animals 4 that have entered or approached a field 3, and comprises: multiple infrared sensors 11 and 52 arranged in the field 3 that detect when pest birds and animals 4 have entered detection ranges 11a and 52a; an intimidation robot 20 that, upon receiving a detection signal from the infrared sensor 11, performs an intimidation action to intimidate the pest birds and animals 4 within or near the detection range 11a where the intrusion of the pest birds and animals 4 has been detected; and an injury simulation robot 30 that, upon receiving a detection signal from the infrared sensor 52, performs an injury simulation action that mimics the injury behavior of a mallard duck within the detection range 52a where the intrusion of the pest birds and animals 4 has been detected.

[0047] With this configuration, the injury-simulating robot 30 performs actions that mimic the injury-simulating actions of a mallard duck near the intimidation robot 20, which performs intimidation actions. This makes the pest bird 4 perceive the injury-simulating robot 30 as having been attacked and injured by the intimidation robot 20, thus efficiently driving the pest bird 4 away from the field 3. Furthermore, the intimidation robot 20 and the injury-simulating robot 30 appear each time the pest bird 4 flies in and work together to drive it away, preventing the pest bird 4 from becoming accustomed to the control measures and allowing the control effect to be obtained over a long period of time.

[0048] Furthermore, in this embodiment of the pest bird and animal control system 1, multiple infrared sensors 11 are placed within the field 3 to detect when a pest bird or animal 4 enters the detection range 11a. When the intimidation robot 20 receives a detection signal from the infrared sensors 11, it travels to or near the detection range 11a where the infrared sensors 11 detected the intrusion of the pest bird or animal 4, based on the position information of the detection range 11a where the infrared sensors 11 detected the intrusion of the pest bird or animal 4, and performs an intimidation action.

[0049] With this configuration, the deterrent robot 20 travels to the detection range 11a where it detected the harmful bird or animal 4 each time it flies in, and deters the harmful bird or animal 4. This prevents the harmful bird or animal 4 from becoming accustomed to the control measures, thereby enabling the control effect to be obtained over a long period of time.

[0050] Furthermore, in this embodiment of the pest bird and animal control system 1, multiple infrared sensors 52 are placed within the field 3 to detect when pest birds and animals 4 enter the detection range 52a. The injury simulation robot 30 is positioned within the detection range 52a of the infrared sensors 52 when in standby mode, and when it receives a detection signal from the infrared sensors 52, it performs an injury simulation operation of a mallard duck within the detection range 52a.

[0051] With this configuration, the injury-simulating robot 30 performs an injury-simulating action of a mallard duck within the detection range 52a where it detects the harmful bird or animal 4 each time it flies in, thereby suppressing the harmful bird or animal 4 from becoming accustomed to the control and enabling the control effect to be obtained over a long period of time.

[0052] In this embodiment, the example described is when the injury simulation robot 30 travels within the field 3 by the travel unit 31. However, the configuration in which the injury simulation robot 30 moves within the field 3 is not limited to this. For example, wires or rails may be stretched at a predetermined height within the field 3, and a pulley suspending the injury simulation robot 30 may rotate on the wires or rails, thereby causing the injury simulation robot 30 to move along the wires or rails.

[0053] <Second Embodiment> Next, a pest bird and animal control system 1 according to the second embodiment of the present invention will be described. The pest bird and animal control system 1 according to this embodiment mainly suppresses the approach of pest birds and animals 4 such as deer and wild boars to a field 3 surrounded by a fence 2. The pest bird and animal control system 1 according to the second embodiment differs from the pest bird and animal control system 1 according to the first embodiment described above in that the sensor unit 10 is installed on the outer perimeter of the field 3 and a robot that imitates a wild boar is used as a simulated injury robot. However, other components are common, so a description of the common components will be omitted.

[0054] Figure 8 is a schematic diagram showing the pest bird and animal control system 1 according to this embodiment. The sensor unit 10 is installed on the outer perimeter of the fence 2 that covers the field 3. The infrared sensor 11 is positioned so that there are no blind spots in the detection range 11a around the field 3.

[0055] When the control unit 23 of the intimidation robot 20 receives the detection signal from the infrared sensor 11 and the location information of the detection range 11a where the harmful bird or animal 4 was detected via the communication unit 22 and a network (not shown), it retrieves a travel route from the first storage unit 40 to the detection range 11a where the harmful bird or animal 4 was detected, which is stored in the memory unit 24, and drives the travel unit 21 along the travel route, causing the intimidation robot 20 to travel toward the vicinity of the detection range 11a of the infrared sensor 11 where the harmful bird or animal 4 was detected.

[0056] When no harmful birds or animals 4 are detected, the injury simulation robot 30 remains stationary in the second hangar 50. The second hangar 50 is equipped with an infrared sensor 52 that detects the approach of harmful birds or animals 4. When the infrared sensor 52 detects that harmful birds or animals 4 have entered the detection range 52a set around the second hangar 50, it outputs a detection signal. When the infrared sensor 52 detects the approach of harmful birds or animals 4, the control unit 53 sends a detection signal to the injury simulation robot 30 via the communication unit 54 and a network (not shown) to inform it of the intrusion of harmful birds or animals 4.

[0057] As shown in Figure 9, it is preferable that multiple second storage units 50 are provided within the field 3 so that harmful birds and animals 4 can be driven away no matter where they appear on the outer perimeter of the field 3, and that the injury simulation robots 30 are stored in each of the second storage units 50. In the layout shown in Figure 9, the second storage units 50 are arranged around the perimeter of the field 3 with gaps between them.

[0058] As shown in Figure 10, the injury simulation robot 30 is a robot modeled after a wild boar. However, the model for the injury simulation robot 30 is not limited to a wild boar; it could also be a deer or another animal.

[0059] The main body 39 comprises a torso 39a, a head 39b, legs 39c, and a tail 39d. The size of the main body 39 is set to be close to the size of a real wild boar.

[0060] A hole 39aa is formed in the torso 39a. By releasing smoke or the like from a smoke generator (not shown) installed in the hole 39aa in conjunction with the flapping of the legs 39c and tail 39d, it is possible to simulate being shot. In addition, a speaker 39ab built into the torso 39a emits sounds such as a wild boar's scream, gunshots, a dog barking, or an attack.

[0061] The four legs 39c and tail 39d are connected to the torso 39a via joints (not shown), and the legs 39c and tail 39d are configured to swing around the joints by actuators (not shown).

[0062] The running section 31 includes a caterpillar track 31c provided below the body section 39a, and a support column 31d erected vertically from the caterpillar track 31c, with its tip rotatably supporting the body section 39a. The wound simulation robot 30 moves when the caterpillar track 31c is driven.

[0063] When the control unit 33 receives a detection signal from the infrared sensor 52 that has detected a harmful bird or animal 4 via the communication unit 32, the injury simulation robot 30 exits the second storage bay 50 and performs actions that mimic the injury actions of a wild boar for a predetermined time (for example, 20 seconds).

[0064] Here, the actions performed by the injury-simulating robot 30 to mimic the movements of a wild boar that

[0065] Then, the injury-simulating robot 30 performs actions that mimic the injury-simulating behavior of a wild boar near the intimidating robot 20, which performs intimidating actions, thereby making the harmful bird / animal 4 believe that the injury-simulating robot 30 was attacked and injured by the intimidating robot 20.

[0066] Thus, the pest control system 1 according to this embodiment is a pest control system 1 that drives away pest birds 4 that approach a field 3, and comprises: multiple infrared sensors 11 arranged around the outer perimeter of the field 3 to detect when pest birds 4 enter a detection range 11a; multiple infrared sensors 52 arranged inside the field 3 to detect when pest birds 4 enter a detection range 52a; a threatening robot 20 that, upon receiving a detection signal from the infrared sensor 11, performs a threatening action to intimidate the pest birds 4 near the detection range 11a where the intrusion of the pest birds 4 was detected; and a simulated injury robot 30 that, upon receiving a detection signal from the infrared sensor 52, performs a simulated injury action of a wild boar within the detection range 52a where the intrusion of the pest birds 4 was detected.

[0067] With this configuration, the injury-simulating robot 30 performs actions that mimic the injury-simulating actions of a wild boar near the intimidation robot 20, which performs intimidation actions. This makes the pest bird 4 perceive the injury-simulating robot 30 as having been attacked and injured by the intimidation robot 20, thus efficiently driving the pest bird 4 away from the field 3. Furthermore, the intimidation robot 20 and the injury-simulating robot 30 appear each time the pest bird 4 approaches and work together to drive it away, preventing the pest bird 4 from becoming accustomed to the control measures and allowing the control effect to be obtained over a long period of time.

[0068] Furthermore, in the pest bird and animal control system 1 according to this embodiment, multiple infrared sensors 11 are arranged around the outer perimeter of the field 3 to detect when a pest bird or animal 4 enters the detection range 11a. When the intimidation robot 20 receives a detection signal from the infrared sensors 11, it travels to the vicinity of the detection range 11a where the infrared sensors 11 detected the intrusion of the pest bird or animal 4, based on the position information of the detection range 11a where the infrared sensors 11 detected the intrusion of the pest bird or animal 4, and performs an intimidation action.

[0069] With this configuration, the intimidation robot 20 moves to the vicinity of the detection range 11a where the harmful bird or animal 4 was detected each time the bird or animal 4 approaches, intimidating the bird or animal 4. This prevents the bird or animal 4 from becoming accustomed to the control measures, thereby ensuring a long-term control effect.

[0070] Furthermore, in this embodiment of the pest bird and animal control system 1, multiple infrared sensors 52 are placed within the field 3 to detect when a pest bird or animal 4 enters the detection range 52a. The injury simulation robot 30 is positioned within the detection range 52a of the infrared sensors 52 when in standby mode, and when it receives a detection signal from the infrared sensors 52, it performs an injury simulation operation of a wild boar within the detection range 52a.

[0071] With this configuration, the injury-simulating robot 30 performs an injury-simulating action of a wild boar within the detection range 52a where it detects the harmful bird or animal 4 whenever the bird or animal approaches. This suppresses the harmful bird or animal 4 from becoming accustomed to the control measures, thereby enabling the control effect to be obtained over a long period of time.

[0072] Furthermore, the present invention can be modified in various ways without departing from the spirit of the invention, and it goes without saying that the present invention extends to such modifications. In addition, the embodiments described above may be combined as appropriate. [Explanation of symbols]
