Description

A STRUCTURE AND PROCESSING METHODS OF MOCK GRENADE}

The grenade of the present invention, more specifically, a training grenade having a grenade appearance that can be used for combat simulation by simulating an explosion and its fragments by the operation of an electronic circuit, rather than the actual bomb explosion. In the following, this equipment is referred to as simulated grenade.

In general, the Miles System (MILES System) is a system that determines whether or not to hit by firing a laser light instead of a bullet, military and civilian has adopted this as an infantry combat training system.

Briefly, the soldiers participating in the training aim at the target and pull the trigger of the personal or common weapon, and at this time, the sensor mounted on the trigger recognizes the trigger pull, Light is detected by an acoustic sensor or a light receiving sensor to activate a laser firing device mounted on the soldier's firearm, from which a pulsed infrared laser is fired at the aimed target. If the fired laser hits all or part of a plurality of sensing elements of a sensing device mounted on the outside of the target, such as a helmet, a body harness, or a tank of each soldier, the laser incident on the hit sensing element After the signal is converted into an electrical signal, the signal is recognized as a shot signal, and visually and audibly is displayed by a warning light mounted on the soldier's body according to a predetermined logic. The signal is transmitted to a central control system located at a remote location, where it can be controlled centrally.

Until now, such a Miles system or simulated warfare system has always been a system that simulates only firearms. This was because the guns were intuitively identical or similar in laser firing, but the problem was that the situation did not create a simulation system for grenades, one of the most important elements of infantry firearms.

Another reason why this grenade simulation system was not developed was that there was no idea of how laser beams could be used to simulate a bomb that would cause damage to a certain radius, even if it felt necessary. to be.

However, grenades were extremely important tactical weapons in infantry combat, so the Miles system was not a good combat simulation system, so training was incomplete.

The present invention has been made to solve the above-described problems, and the object of the present invention is to provide a structure and a method of operation of a simulated grenade which can be applied to an existing Miles system without using gunpowder and whose throwing method is very similar to a real grenade. do.

Another object of the present invention is to provide a structure and a method of operating a simulated grenade capable of realistically realizing various explosion situations occurring when the grenade explodes in the simulated grenade.

It is another object of the present invention to provide a structure and a method of operation of a simulated grenade capable of emitting a collection signal for facilitating collection of simulated grenades after the training is completed.

In addition, the operation method of the simulated grenade of the present invention for achieving the above object, removing the safety pin mounted to the outside of the simulated grenade housing; Rotating the lever fixed by the safety pin about a rotating shaft fixed to the exterior of the grenade housing; Generating a detonation signal by pressing one end of the detonation signal generation switch as the lever rotates; Transmitting the generated initiator signal to an explosion activation signal generator; Generating an explosion activation signal by the explosion activation signal generator; Transmitting the generated explosion activation signal to the explosion signal generator; Generating an explosion signal by the explosion signal generator based on the explosion activation signal; Radiating the generated explosion signal radially out of the simulated grenade housing; Characterized in that it comprises a.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

< Explosion Signal Generation System>

1 is a block diagram of the modules of the simulated grenade of the present invention. The simulated grenade of the present invention has a shape similar to that of a real grenade and a detonation signal is generated when a thrower throws and throws a safety pin like a real grenade in and out of a housing 10 made of a material having elasticity such as polyurethane or rubber. Part 100, the explosion activation signal generating unit 200 receives the detonation signal to generate an explosion activation signal and the explosion signal generating unit 300 to generate an explosion signal to simulate the explosion fragments of the grenade by the explosion activation signal It is configured to include).

2A and 2B schematically show the detonation signal generating unit 100 mounted on the outside and the inside of the simulated grenade housing 10 of the present invention, respectively, showing before and after removing the safety pin.

Simulation grenade of the present invention is configured as close to the actual grenade as possible, the operation method of the detonation signal generator is similar to the actual. That is, when the safety pin 104 connected to the safety ring 102 is inserted into the safety pin receiving groove 110 of the lever support 108 so as not to move the lever 106 and pulled it out for throwing, the lever is free to It can rotate. That is, when the thrower throws the simulated grenade, the grip force that presses the lever 106 is lost, so the lever 106 is rotated about the rotating shaft 114 while being pushed by the elastic force of the lever spring 112 installed on the side of the grenade body. The end is pressed against the switch bar 116 connected to the grenade inner module. When the switch bar is pressed, it pushes the detonation signal generation switch 118 inside the body to generate the detonation signal. The switch bar 116 is later restored to place by the elastic body 117.

The safety ring and safety pins may be configured to be always fixed to the mock grenade body by a connecting line (not shown) to prevent loss during throwing and management.

In the above-described manner, the apparatus for generating the initiator signal may use various methods. For example, referring to another embodiment of FIG. 2C, this time the safety pin 104 ″ attached to the safety ring 102 is pulled out so that the lever 106 can be rotated about the rotation axis 114. When the thrower presses the lever with a grip force, it may press the switch bar 116 " and the lower signal generating switch 118 " below to generate the detonation signal.

FIG. 2D illustrates another method of the switch for generating the detonation signal. Unlike the above-described embodiments, the detonation signal is generated by simply pulling out the safety pin. That is, when the safety pin 104 is pulled out, the switch bar 116 'is pulled in the direction of the arrow by the spring 117' at the bottom to press the initiator signal generation switch 118 'to generate the initiator signal. In this case, the lever 106 or the like does not move and is merely a model that simulates the shape of the actual grenade. In general, when the safety pin is pulled out, most of the throwing is performed within 1 to 5 seconds. In this case, a longer setting may be simulated in consideration of the generation time of the explosion activation signal, which will be described later. This simple configuration is advantageous for the production and maintenance of simulated grenades.

Although the detonation signal generating switch may be mechanically pushed as in the switch bar described above, it is natural that the position or shape of the switch bar may be pushed or pulled by the spring to form an energization circuit in the detonation signal generating switch to generate the detonation signal. It's work.

The detonation signal generated in this way is transmitted to the explosion activation signal generation unit 200 made of a microcomputer.

3 is a block diagram of the explosion activation signal generator 200. The explosion activation signal generated by the explosion activation signal generator of the present invention may be generated in two modes, a time delay mode and an impact mode.

The time delay type is a predetermined time set in advance, for example, 3 to 6 seconds while receiving information on the time from the timer 204 in which the microcomputer 202 of the explosion activation signal generator 200 receives the detonation signal. As a method of generating an explosion activation signal, it simulates a time-delayed explosion mode in which a detonator and an explosive explode only when a predetermined time elapses as the delay fuse is burned after the actual grenade strike.

In another method, the impact explosion type, when the shock signal transmission module 206 mounted on the simulated grenade body is activated according to the detonation signal, the simulated grenades hit somewhere and the impact sensor 208 detects a predetermined shock. Accordingly, the shock signal transmission module 206 transmits that the microcomputer 202 has been impacted, thereby generating an explosion activation signal, which simulates the grenade exploding while hitting the ground after throwing. Such a shock sensor 208 is a method for mounting a conventional dielectric sensor or the like one or more places inside and outside the grenade body and connecting it to the shock signal transmission module 206, so that those skilled in the art can easily configure It is not described in detail any more.

The simulated grenade of the present invention can be basically configured to simulate only one of a time delay type and an impact explosion type, but can also be configured to variably simulate these two modes according to the mode conversion switch 210.

When the explosion activation signal generator 200 generates an explosion activation signal based on the detonation signal, the explosion activation signal generator 200 transmits the explosion activation signal to the explosion signal generator 300. 4 is a block diagram illustrating an explosion signal generation unit.

The explosion signal generating module 302 of the explosion signal generating unit 300 which has received the explosion activation signal is a laser emitting device 304-A or an RF signal emitting device 304 that emits laser light belonging to an infrared or visible light wavelength region. The explosion signal generating element 304 composed of at least one of -B) is controlled to emit a laser light or an RF signal radially around the simulated grenade as an explosion signal. This explosion signal is used as a signal to simulate the fragments generated during the actual grenade explosion.

Since the laser light or the RF signal is intended to simulate the actual grenade explosion, it is preferable to use an infrared laser or an RF signal having a strong straightness. It could also be a simple light or radio signal, but it could also contain the Miles code used in an engagement training simulation system called MILES (Multiple Integrated Laser Engagement System). The Miles code is a code signal well known in the Miles system field, and is generally composed of a plurality of pulse waveforms. The Miles code emitted from the simulated grenade of the present invention includes the type of the grenade, the ID of the thrower, and / or the effective radius of the damage. It can be configured to distinguish between the other noise signal and the hit signal, and at the same time, it can be configured to know how much and who was hit by which weapon.

The information included in the miles code is read by the microcomputer and stored in the memory device 306 composed of flash memory or FeRAM, and transmitted to the explosion signal generation module 302 to be included in the miles code. In the drawing, it is shown that the memory device 306 is connected to the explosion signal generation module 302, which is functionally illustrated as the information stored in the memory is directly transmitted to the explosion signal generation module. . In addition, since the explosion signal generating element 304 is partially exposed to the body surface to emit the explosion signal to the outside of the simulated grenade, the block diagram is also shown to the outside of the explosion signal generator 300 to schematically illustrate the explosion signal. It protrudes.

FIG. 5A is a schematic diagram of an appearance of a simulated grenade of the present invention in which an explosion signal generating device 304 is implemented, and FIG. 5B is an enlarged cross-sectional view of part A-A 'of FIG. 5A.

The above-described laser emitting device 304-A is generally configured by arranging a plurality of semiconductor lasers 502, such as GaAs, InGaAlP, GaN series, which emit infrared or visible light, on the outer surface of the grenade housing. Is exposed. In addition, the convex lens-shaped transparent epoxy 504 may be coated on the upper portion of the upper surface of the projection B to protect the laser exit value from external impact.

The laser emitted from the semiconductor laser 502 radiates radially around the simulated grenade to simulate fragments of the grenade. Its output is also adjusted to have a certain power within a certain distance to simulate the kill radius of the actual grenade. For example, if it is a signal having an effective strength only within a distance of 5 to 10 meters from a simulated grenade and the detected sensing element is treated as an exposure, the value detected at a distance farther than the set distance will be less than the effective strength. Therefore, even if the shot detection device (not shown) detects this, the signal can be processed as a noise that falls below the threshold.

The above-described RF signal emitting device 304-B emits an RF signal to the outside of the simulated grenade through the RF antenna 508. Such an RF antenna may be installed anywhere outside the simulated grenade housing, but may be mounted on the side of the lever support 108 described above to be strong in impact or the like. At least one RF antenna 508 is mounted so that a strong RF signal including a Miles code is emitted spherically or radially within the effective radius. This RF signal can also be adjusted to a constant output to simulate the effective radius like the laser beam described above.

FIG. 6 schematically illustrates a method in which a shot detection device that detects a laser signal or an RF signal, which is the explosion signal described above, operates.

When the explosion signal from the simulated grenade is detected by the hit detection element 602, the Miles code is wirelessly transmitted to the central control system 606 through the detector communication unit 604 connected to the hit detection element, so that the corresponding detection element 602 is detected. Or) Report the attack and / or extent of the soldier wearing this sensing element. At the same time, the soldier's weapons and other combat status will be deactivated so that they can no longer participate in the battle. This method is similar to the mimicking situation of the conventional Miles combat system, so detailed description thereof will be omitted. For reference, the above-described hit detection element 602 may be attached to the outer shell of the tank or other equipment as well as soldiers, in this case, if the hit is carried out in the manner of half-wave, slow wave and the like.

As such, when the simulated grenades of the present invention are thrown to emit an explosion signal in all directions and simulate the explosion, the soldier or a target equipped with the sensing element is detected, and the simulated grenades of the present invention have the same effect as the actual grenades. Will be copied.

Explosion Effect Simulation System

The simulated grenade of the present invention described above only simulates explosion and basic operation. Yet another embodiment of the present invention may further include an explosion effect simulation unit 400 that allows the explosion to be simulated more realistically in addition to the basic configuration and operation.

7 is a block diagram of the simulation grenade of the present invention in which the explosion effect simulation unit is implemented. In FIG. 7, when the microcomputer transmits an explosion activation signal, the microcomputer operates in a general manner in which the switch of each device is turned on by the driving module of each device.

Explosive effect simulation unit of the present invention, explosion flash generating device 422 to simulate the flash generated during the grenade explosion, explosion sound generating device 424 to simulate the explosion sound generated during explosion, explosion smoke screen to simulate the smoke generated during the explosion At least one of the generating device 426 is to be aimed at the effect of increasing the training effect of the soldiers. The driver or driving module 412, 414, 416 for driving the respective devices may be separately configured as shown, but may also be configured as one integrated module 410.

Hereinafter, each configuration of the explosion effect simulation unit will be described in detail.

8A is a schematic view of the appearance of the simulated grenade in which the explosion flash generating device 422 is implemented. LED device 422-A, which is one of various light emitting devices that can be used as an explosion flash generating device, is formed in a form embedded in a simulated grenade surface separately from the laser emitting device. Like laser emitting devices, these LEDs emit light radially around grenades. When several LEDs are turned on momentarily, enough illumination can be emitted to simulate bright flashes even in daylight. Although it is preferable to use LED which emits white light as said LED element, it can also comprise red or a combination of such multicolored LED elements. In addition, the grenade body side, which is a portion where stronger light is required, is also possible to increase the glare effect with the LED layer 422-B in which LEDs are concentrated and arranged.

In addition to the LED of the flash device of the present invention, a laser diode (LD), CCFL, and other light emitting media are possible.

Another device of the explosion effect simulation means is the explosion sound generating device 424. 8B schematically illustrates the appearance of the simulated grenade grenade of the present invention equipped with an explosion sound generating device, the explosion sound generating device of the present invention may be composed of a small speaker or a small explosion device, and the microcomputer generates an explosion activation signal. When transferred to the acoustic device driving module 414, the driving module turns on the speaker or the small explosive device so that the explosion sound is emitted to the outside through the protective mesh of the grenades surface.

To prevent the surface of the protective mesh from touching the ground and releasing sound well after the grenade is thrown, the speaker or the small detonation device and the protective mesh 424-A of the surface may be configured to surround the outer surface of the grenade housing. . However, a speaker or a small drinking apparatus may be disposed in other locations, and further, the sound may be emitted in all directions through the acoustic sphere 424-B formed around the body. The compact drinking apparatus that can be used in the present invention is a general military drinking apparatus having a cylindrical diameter of 0.5 to 1 cm and a length of 1 to 5 cm.

Another device of the explosion effect simulation means is the explosion smoke generating device 426. Figure 8c is a sectional view showing only a part of the mechanical configuration for this explosion smoke generating device is to simulate the smoke generated when the grenade explosion.

In response to the explosion activation signal transmitted by the microcomputer, the smoke agent 426 mounted with the smoke device driving module 416 is ignited, and the smoke generated therefrom is rapidly emitted through the smoke dissipation port 427 disposed above the safety handle support. It can be the way. The smoke agent used in the present invention may be a cylindrical military smoke agent having a diameter of 0.5 cm and a length of 1 to 3 cm, and the driving module 416 operates the piezoelectric body 428 according to the explosion activation signal and generates electricity from the piezoelectric body. The lower part of the smoke agent 426 is ignited by the spark. Another way of arranging the smoke emanation port is formed in various parts of the grenade body, similarly to the arrangement of the explosion sound generating device, and the smoke spreads in all directions through the plurality of emanation holes (not shown).

< Collection signal generation system>

Another embodiment of the present invention further includes a collection signal generating unit for facilitating the collection of simulated grenades after the training ends.

The training ground using the simulated grenade of the present invention is a place where concealed and covered objects and rocks, grass, etc. are mixed, so it is not easy to collect the thrown grenades. Therefore, in order to facilitate such collection, after the end of the training, a speaker, an RF antenna, and a light emitting body mounted on the mock grenade body may emit a sound, light, signal, etc. that actively announces its position by itself. have.

The collection signal generator can be activated in several ways. One of them is to predict the end time of training on the basis of the predetermined training time or the average training time in advance, and then use the timer to activate the collection signal generation means automatically by the microcomputer. In another method, a radio signal indicating the end of training is transmitted from an antenna installed throughout the training center by the central control system, and the thrown grenade RF antenna receives this signal and the RF receiver notifies the microcomputer of the completion of the training. From this time, the collection signal generator is activated.

 In addition, after the simulated grenade explodes, it can automatically determine that it is a trained equipment and generate a collection signal.

The collection signal generator used in the present invention may use at least any one of an RF signal, light, sound, smoke, or shape deformation.

In the collection method using the RF signal, when the microcomputer commands the collection signal generation unit to activate the collection signal, the above-described RF signal output device 304-B receives the RF collection signal that the collection sensor can detect. ) Then, soldiers wear detectors that can detect the RF collection signal, move around the training ground, and detect the location of the grenade according to the strength of the RF signal and collect it.

The light collecting method may use the above-described laser output device 304-A or the explosion flash generating device 422 as it is. When the collection signal activation command is transmitted by the microcomputer, the laser output device may emit visible light laser or LED light. Periodically exit or flash to allow soldiers to locate the simulated grenade with the naked eye. If the infrared laser is emitted, it is also possible to detect and collect its position and intensity with the above-described hit detector or a similar detector capable of detecting the same.

The collection method by sound may also be used by the soldier who makes a sound using the above-mentioned explosion sound generating device 424 and detects the same, and the smoke screen is also used in the above-described explosion smoke generating device 426. By using the remaining smoke agent or a separate collection of smoke agent configured to separate the smoke to create a smoke to the naked eye.

Such various collection methods can be easily configured by those skilled in the art using the above-described apparatus.

One of the collection methods, which is an embodiment of the present invention, is a form of grenade, for example, a foldable bar mounted inside a grenade body, which can be divided by the naked eye by being automatically extended by using a motor mounted therein. will be. FIG. 9 is a schematic representation of one embodiment, wherein a long stick of the same or similar form as a foldable foldable antenna is adapted to be stretched outside the grenade by a motor in accordance with a collection signal in the same manner as a radio antenna of a car. Can be. These foldable bars can also be colored on the end of the bar to enhance the visual effect.

At least one, preferably two or more, of the above-mentioned collection signal generating means may be used at once.

When the grenade is collected, the collection signal does not need to be operated anymore, so the external switch may be turned off or a safety pin may be inserted to stop the collection signal generator.

When the collection is completed, when the safety pin is inserted or the reset switch is pressed, the training data stored in the storage device is deleted and the device is reset to the state for the next training.

<Structure for Shock Mitigation>

The simulated grenade body and shell of the present invention are made of a material and form resistant to impact in order to protect the internal elements.

FIG. 10 is a sectional view taken along line C-C 'of the simulation grenade of the present invention having such a shock-absorbing structure, the grenade main body shell 1010 is made of hard rubber or polyurethane while having elasticity. It is configured to absorb the shock itself. In addition, the interior of the various circuit boards and devices are filled with silicon (silicone, 1020) can be configured to protect the interior against the impact transmitted from the shell.

This structure is first made of a polyurethane shell divided into two or more parts, and the elements and various substrates are placed therein, then the two shells are assembled to the correct position to confirm the operation of the device and the inside is filled with silicon again to the final product Can be made to complete the step.

FIG. 11 is a view showing another embodiment of the present invention for protecting an element exposed to the outside from impact, and when a cross section taken along the line d-d 'is a polyurethane jacket made of a laser emitter in the form of a dimple 1110; FIG. Located inside, the polyurethane sheath is configured to receive the most impact when it hits the ground.

The dimple structure or the protruding protective structure may be equally applied to various external exposure elements such as the speaker and the flash device described above.

<Data entry step>

The grenade of the present invention can be connected to a wired or wireless device such as a computer, a reader, a recorder, or the like through an RF antenna, an RS232 port, or a USB port connected to the grenade shell. Through the input / output connection terminal, the ID of the thrower or the like may be input or the internal data may be output.

In addition, even in the case of one type of grenade, in order to simulate various types of grenades having different effective radius and explosive method, the type and the effective radius may also be inputted at the time of training.

<Self-check and overall operation stage>

The operation method of the above-described simulation grenade of the present invention is as follows.

12 is a block diagram of a mock grenade in which the self-check circuit 1200 and other modules of the present invention are implemented based on a microcomputer. The self-check circuit is a diagnostic circuit that checks for a failure by checking a response signal after sending a predetermined signal to each device and modules. The self-check circuit of the present invention is particularly important because of its special use environment. .

Fig. 13 is a flowchart showing the overall operation of the simulation grenade of the present invention including this self-check circuit.

First, in FIG. 13A, when the initial power is turned on (S10), the self-check circuit 1200 of the grenade grenade checks a response signal of a battery and each electric module and elements (S14). If the battery charge is insufficient or abnormal operation module is found during the inspection, it is reported to the circuit inspection device connected to the input / output terminal (S16) and waits (S20). When an abnormality is reported, the user turns off the power, replaces the module, or recharges the battery to correct the abnormality. If no abnormality is found, the user may input initial information, such as the thrower ID of the simulated grenades and the damage radius of the corresponding grenades through the data input unit connected to the input / output terminal (S18).

When this input is completed, all systems of the simulated grenade wait until the start of training and grenade throwing (S20). The power may be turned off automatically or by the user to reduce battery consumption during standby.

In addition, a switch for turning on the power may be provided separately, but for the sake of simplicity, the power pin may be automatically turned on when the safety pin is removed. In other words, if the lever is not held by the detonation signal switch after the safety pin is pulled out, the microcomputer checks the abnormal operation of each of the above-mentioned parts at that stage and prepares for throwing or waits for data input. It may also be configured to write data to the storage element by inputting data to the port.

Figure 13b shows the actual explosion signal generation step after the atmosphere. Once the safety pin is pulled out and thrown, as shown in FIG. When the end of the detonation signal generation switch is pressed by the rotation of the lever, the detonation signal (S21) is generated therefrom, which is transmitted to the explosion activation signal generating unit, and is transmitted to any one of the two modes described above, namely, time delay mode and impact mode. Therefore, an explosion signal is generated. In the time delay mode, the timer is turned on (S22) and the explosion activation signal generator receives the information about the time, checks that the predetermined predetermined delay time has elapsed (S23), and generates an explosion activation signal (S26). In the mode, after activating the shock signal transmission module (S24) and receiving the shock detected by the mounted shock sensor, comparing it with a predetermined value set in advance (S25) and generating an explosion activation signal (S26) as described above. same. The shock must be greater than or equal to the predetermined value in order to prevent the explosion signal from being generated by the slight shock or noise other than the impact caused by the throwing.

The generated explosion activation signal is transmitted to the explosion signal generating unit to generate an explosion signal, and before and after this, to operate the explosion effect simulator to generate sound, sound and smoke. The grenade then waits for the training to end. This is also as described above.

Figure 13c shows the collection signal generation and collection step after the type of training.

After the explosion signal is generated, the simulated grenade waits for the preset training end time to pass (S30) or receives the training end signal emitted from the central control system (S31).

Next, by operating the collection signal generator to generate a collection signal (S32) to notify the outside of its position while waiting for the collection is collected and the safety pin is inserted again or other collection (S33) and the collection signal ends ( S34).

If necessary, the data stored in the collected grenade grenade, for example, after the data reading step to confirm the explosion signal generation time, etc. (S35) and then reset the data and other devices for training (S36) and the power is turned off (S37).

In the above-described method, when a predetermined time elapses after a detonation signal or a predetermined shock is applied, an explosion signal may be emitted by operating the explosion signal generator immediately without an explosion activation signal. FIG. 14 is a block diagram of this, in which case the explosion activation signal or the explosion activation signal generating unit does not exist separately, and the intermediate transfer module 1410 of the intermediate transfer unit 1400 receiving the explosion signal is a timer or an impact sensor. When the predetermined time elapsed or a predetermined shock therefrom to activate the explosion signal immediately to the explosion signal generating unit to generate an explosion signal.

As described above, the simulation grenade of the present invention generates an explosion activation signal by the microcomputer according to the detection of the detonation signal, and the explosion signal generating means receiving the explosion activation signal simulates the miles code, which is a hit signal, through a laser exit device or an RF signal output device. Generates a constant output in all directions to reach the soldier or target's hit detector. When the Miles code is received by the hit detector, it is simulated as being hit by a grenade fragment and the signal is sent to the central control system to treat the soldier or target as being hit.

Therefore, it is thrown in the same way as a real grenade and simulated an explosion in the same way, so it is designed to effectively carry out simulated combat training of infantry.

In addition, the present invention is to pursue the convenience of the maintenance and management of the device at the same time by having a device that can increase the training effect by realistically processing the explosion effect and facilitate the collection after the end of training.

Such simulated grenades of the present invention contain various modifications. For example, the embodiments of the present invention have been described as limited to grenades, but in addition, the principles of the present invention can be used to mimic other explosives having cremoans and fuses that explode at a certain radius. In addition, by adding a GPS module to the grenade can be configured to make collection easier.
