Description:
RONI - Explosives detection and disposal drone

TECHNICAL FIELD

The invention relates generally to drones, and more particularly to a Quadcopter drone that houses an integrated camera system, an explosives' detector, and a laser driver.

The exemplary embodiments described herein generally relate to drones, cameras, processors, actuators, motors, batteries, receivers/ transmitters, and laser drivers.

BACKGROUND ART

Referring to the prior art, there has been no art with the same capabilities. The prior art US61 13343A, Explosives disposal robot, which is still in operation, cannot reach for high grounds; and in most cases may be damaged partially or wholly by the explosion, as it comes very close in contact with the explosive. This makes the process very costly.

That prior art deal mechanically with the explosive, handling it with a robotic arm to attempt disposing the explosive, which is not always a successful mechanism, especially if the explosive is made by a sophisticated tech, or even wrapped in a shockproof bubble bag; and requires more than a shock impact to explode.

However, this invention is not meant to replace the valuable previous art US6113343 A, as it has different scope of applications.

A related art to this invention is the four-rotor aircraft CN 203318680 U, Remote-control flying copter and method US 20140099853 Al, Quadrotor model helicopter airframe US D710453 SI Laser diode power control and modulator circuit US 4868836 A, Laser pointer with multiple color beams US 20020071287 Al, Laser welding system US 5616261 A and Apparatus and method for the detection of materials US 6344818 Bl .

DISCLOSURE OF THE INVENTION

In view of the foregoing, the present invention relates to an apparatus and method of detecting the presence of explosives and safely detonates them.

It is an object of the present invention to provide an apparatus and method to remotely detect and detonate explosives.

Another object of the present invention is to provide remote detection and detonating system with a certain information monitoring system that can be controlled with one person.

Still another object of the present invention is to provide the Public Safety Bomb Disposal (PSBD) and the Bomb Squad personnel with a different, safer approach to disable explosives.

Still another object of the present invention is to identify the explosive and estimate the possible explosion range and possible options of disarming the explosive.

Other objects and advantages of the present invention will become more obvious hereinafter in the specification and drawings.

Referring now to the drawings, and more particularly to FIG. 1, a plan view of the

embodiments of the present invention is shown and referenced generally by the name "RONI" or "Roni". The components will be clearly illustrated in further drawings. Specifically, the relevant structural features of Roni shown in FIG. 1 are a housing for the CPU, circuits and battery 1, the four propellers 2; connected to the motors 1 1 that run the propellers and capped with the propellers' hoops 15. An EF camera 3 with a memory is fixed on a motor 9 to be able to rotate 360 degrees, from behind the camera and as appear under it is the laser device 5 and the camera motor 9, the laser, and the detector 6 so that the camera, the detector and the laser device moves simultaneously in the same direction, allowing the laser to target exactly where the camera is looking, the explosives detection device 6 is connected to an actuator 8 to operate it and draw in/out its retractable antenna 7. The explosives detector, camera and the actuators have their own control unit, a microprocessor, board and batteries 16 housed together, different of those operating the copter to fly and hover; in order to avoid exhausting the battery of the quadcopter and to save the energy for flight and hovering. The camera may operate at night as it has two front lights above 14, and four landing skids 12 to land safely.

The steps of a method or algorithm described in connection with the embodiments disclosed herein, sending stream images from the camera to the remote control and its screen, may be embodied directly in hardware, in a software module executed by a processor, or in a combination of the two. A software module may reside in RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, hard disk, a removable disk, or any other form of storage medium known in the art.

FIG. 2 is an exemplary circuit to operate Roni, to allow it to fly and hover until its mission is fulfilled.

FIG. 3 is an exemplary drawing of a motor 1 that enables the camera, detector and laser to turn right and left three hundred and sixty degrees, placed on a mount plate 2 and a spinning cylinder 3 where the camera and laser are attached by screws 4.

The mounted detector; patented under no. US 6344818 B,l detects the interference generated between the source energy and the characteristic energy emitted from the material. The interference signal generated between the source energy and the energy emitted from a material is a series of pulses that occur when the two signals cross. The two signals will undoubtedly be out of phase with each other. Since the two signals will be at the same general frequency, however, the interference signal will also be at that frequency. Since the characteristic energy emitted from the target material is a derivative of the characteristic energy, the interference occurs at given intervals. Even though the energy level of the signal emitted by the target material is relatively low, and can be hard to detect on its own, the interference signal is constant and does not depend upon the energy level if the signal emitted by the target source. The interference signal is constant over a wide range and can be detected because of the known parameters of the source signal and the signal emitted by the source. This detector includes a source module and a detection module. The source module generates an energy signal having a given frequency and that corresponds to the characteristic frequency of the material to be detected. The detection module detects the presence of the interference signal that is created between the source energy signal and the energy emitted from the target material at the same frequency as the source signal. The interference signal is dependent upon the characteristic frequency of the target material.

The source module includes a frequency generator that is connected to an antenna that has a given size, or length, that depends upon the wavelength of the energy signal. The source module may also include an inductor so that a multi-phase signal will be emitted.

The detection module includes a rotatable retractable antenna. To improve performance, the antenna can be connected to a signal generator that is preferably set to the characteristic frequency. It is believed that the generator connected to the detection module serves as an amplifier of the interference signal and a filter for surrounding frequencies. The detection module antenna is also connected to a coil that can be tightly wound and oriented in a vertical direction relative to ground and perpendicular to the antenna. The detection module can include a modulator that is set to a relatively small frequency as compared to the source signal. The modulator enhances the detection of the interference signal by the antenna by varying the interference field. The size and orientation of the antenna, the modulator and the detection module source generator are all configured to enhance the ability of the detection module to detect the presence of a material in any given location. It has been observed that the detection device used by the present invention operates optimally when the source generator emits an energy signal of between 100 MHz and 1.5 GHz.

In operation, the source generator is activated to emit an energy signal of a target material's characteristic frequency between 100 MHz and 1.5 GHz. Depending on the power level of the energy source, the source module will begin to activate the electrons of any material that has the characteristic frequency generated within a given area after a few seconds. Once the target material is activated, it too will begin to emit a signal having the characteristic frequency. As will be understood by one skilled in the art, an interference signal at the characteristic frequency will occur between the source signal and the target material signal even though the energy level of the target material signal may be relatively weak.

The detection module is moved through a range between the source module and the target material. When the detection module encounters the highest energy line between the source module and target material, which is the shortest line between the two energy sources, the antenna will rotate to designate that the line has been crossed. Depending on the orientation that the detection module coil is wound, the antenna will rotate in the direction of the target material or the source. As the antenna continues to move through a range it will continue to point in the direction of the source module and the target material. Once a set of co-ordinates for the target material have been generated then the exact location of the target can be calculated. If the exact location of the material is known, as in a suitcase, the microprocessor will - through the camera - start calculating its dimensions, possible weight, and its quantity and range through the detector according to the frequencies analyzed, and then display such information on the screen of the remote control.

The method of attached the control unit to the copter is shown in the control unit (FIG. 1 item 16) is detailed in FIG. 4. This unit attempts to control the camera motor, detector actuator, and the laser device with screws 1.

As clearly illustrated in the drawings, the batteries controlling the motor are different of those powering the 7300 mW laser device. The laser device uses a red laser diode of 650 nanometers (nm) wavelength, and four 26650 4.2 V Li-ion rechargeable batteries. The laser device FIG. 5 consists of a power supply unit (FIG. 5 item 1), transferring power to an adapter (FIG. 5 item 2), which operates the laser driver (FIG. 5 item 3) to emit the laser beam. In the same figure (FIG. 5 item 4) is a small dedicated actuator to act as a focusable mechanism, to control the beam from the pointer (FIG. 5 item 6), a fan (FIG. 5 item 7) cools the laser chamber, and all are housed in a metal housing (FIG. 5 item 5).

FIG. 6 shows an exemplary circuit for the laser driver. Such laser devices and circuits are well known by skilled artisans and are not intended to be protected per se in this document.

In an upside-down view FIG. 7 shows another method to fix the control unit to the copter, there are variety of methods to install the unit to a drone, and this document does not intend to limit such installation model to a certain form. The control unit 1 attached by screws to the hull of the copter, to which is attached the engine 2 that rotates the camera 3, the explosives detector 5 and enables it to draw its antenna 4. The laser 6 is also moving automatically with the mechanism, to focus its pointer 7 on the desired target.

FIG. 8 is an exemplary drawing showing the Quadcopter and the control unit 1 , and its different parts 5, the laser 2 the explosives 'detector3 and its antenna 4.

FIG. 9 is a schematic of the control unit, clearly showing a light metal housing 1 with a mechanism to adjust its dimensions 2, to enable the user to make it bigger to add other embodiments or smaller if it is possible to remove certain embodiments. This housing is fixed to the Quadcopter base with screws through screw cases 3, comprising a batteries 'housing 4 for the laser drive, which will host four 26650 4.2 V Li-ion rechargeable batteries 5, and another housing 6 for the batteries 7 operating the camera, detector 11 , laser rotating mechanism and its motor 9, and also the linear actuator 10 controlling the detector's antenna 12. The laser drive 13, will be adjusted to shoot the laser beam through its barrel 14 and pointer 15 exactly where the camera is looking. A CPU 16 controlling the unit will require an active cooling 17 mechanism using cooler fans. The mechanism, rotating, and laser shooting is controlled remotely; via a receiver/transmitter 8 planted therein and connected to the CPU.

THE BEST MODE FOR CARRYING OUT THE INVENTION

A best mode for the Quadcopter is a water proof device, to be operable in rain. The housing of the embodiments is not desired to add an extra weight or size to the copter, however, the copter should be designed to carry an extra weight of at least 2.7 kilograms. The housing may be of light aluminum.

A microprocessor is the best mode for the present invention; the processor may be 3.5GHz Core i7. The processor, mechanism, and software module should allow the drone to lock and fire on a certain target in case of chasing an explosive planted on a moving vehicle or the copter suffered strong wind while hovering. The rotating mechanism of the camera, detector, and laser should be able to tilt as well as rotate.

The remote control, software module should include all in one remote controlling device. The software hardware module shall also be able to estimate the weight, dimensions of the explosive and the power of the explosion, giving an estimate to the explosion range.

The laser power may be increased to 10 mW laser, which shall require elevating the power source in order to avoid power loss during the process.

Those of skill in the art are sure aware that safety goggles might be necessary while dealing with the present invention with such laser drive.

Adding a safety locking mechanism to the laser by skilled artisan would be recommended to avoid unfortunate accidents while recovering the drone.

A "Cloud" OS platform should be the best recommendation, being able to control and handle multiple Quadcopters at a time, if the process so requires. The software hardware module may include a GPS to allow the copter to return to base automatically if lost or accomplished its mission.

This best mode above does not intend to restrict skilled artisans from any better solutions. The inventor confirms that based upon the written description disclosed; the best mode is flexible for this patent so that a person skilled in the art could practice. INDUSTRIAL APPLICBILITY
