PART-A behind-the-wall radar image processing to locate the

PART-A TITLE: SurveyE  “SurveyE”, is robot that does behind-the-wall radar image processing to locate the people in the building and generates map of the whole building or area and send the details to a remote team . ABSTRACT: Through-the-Wall Surveillance systems are can very well effectuate sneaky operations of safeguarding people from terrorism, crime and also to gather information to search and rescue  victims during disasters with ability to see beyond the walls. For blitzkrieg military operations, self-concealing bots of realizably small size is needed for differentiating enemies inside a building or an area and to generate its map. The idea is to mechanize a robot that can climb, conceal itself, check for the status, location and number of people in a building and differentiate enemies and communicate it to a locator team situated at a distance.

Mobility and camouflaging techniques of robot is such that it can be deployed for surveillance in terrain and sandy areas and also for airborne surveillance. After nearing the spot, TWS systems captures image and send it to the receiver in real time, showing the situation in the spot. In the next step map-products are defined of combinations of the image information layers from radar images. Merging of the different image information layers was done using the RGB to IHS transformation, after which the intensity channels were combined (multiplied or added) followed by IHS to RGB transformation.      Questioner:1.

Motive behind our participation is that we are very much interested in making a world a better place to live to make us all feel secured and sound2. Our knowledge is on the Electronic and communication, machine learning, image processing and artificial Intelligence3. We have been recognized at IIM Bangalore at a DCAL conference to be the best presenters of idea of the show; we have now been selected by the company KPIT as the top 30 for the finals out of 1700 teams all over INDIA4.

We have been recognized at IIM Bangalore at a DCAL conference for paper presentation5.We have a prototype. TECHNICAL CONTENT:Now a day’s many terrorist attacks and crime are in multi-storey buildings. It is challenging for the army or rescue force to penetrate into the building without being noticed. Difficulties are that they don’t know the map of the building and moreover if there are many floors situation becomes worse.

So we are developing a robot that helps the rescue force in many ways. The robot has various features.     Radio range > 1,000m Line Of Sight, > 300m urbanaa Vision 360° Field of View, HD front camera Robustness 1 m drop whatever the direction of impact (3m drop flat on the large size), 10m horizontal throw, IP65 (IP67 optional), operating temperature: -20°C to +55°C Semi-autonomous capabilities Way points navigation, automatic back homing, leader- follower… Weight 5.5 kg Speed 0-4km/h and 0-15km/h Endurance 1h to 3h depending on mission profilea a a  Dimensions Lenght: 350mm; Width: 310mm; Height: 150mm    Map generation.For military purposes it is of importance to have the dispose on actual and accurate terrain information for a specific area of interest anywhere on the world. Geographic information forms only one, but quite essential aspect, in this context. The information on the one side is of importance as a bases for the command and control.

At the other side it is of importance for the operation of individual weapon systems, which all use their own information database. It consists of the division of the terrain into three basic classes:  • Passable terrain (GO TERRAIN) – does not require any additional measures to ensure manoeuvrability for troops operating on it.  • Low-passability terrain (SLOW GO TERRAIN) – reducing the manoeuvrability of troops operating within it, but to a lesser extent than impassable terrain.  • Impassable terrain (NO GO TERRAIN) – hinders the movement of troops in all directions to a very large extent, drastically lowering the speed of movement.          THE PARAMETERS, ACCORDING TO WHICH THE AREA IS CLASSIFIEDINTO ONE OF THREE CATEGORIES OF PASSABILITY:  The constructed system consists of the followingFunctional modules: A.

module for identification and collection of input data in the database;B. data model preparation module;C. cartographic modelling module;D. analysis result visualisation and sharing module.Locomotion and features:The easy-to-use and fully-waterproof   unmanned ground vehicle is protected up to IP65 standard, with an option for IP67 class.It can be fitted with either wheels or tracks, and its lightweight, open-architecture design allows carriage of different interchangeable payloads.

The robot has a length of 350mm, width of 310mm and height of 150mm, and weighs 4.5kg. It has the ability to withstand shocks, vibrations and temperatures up to MIL-STD-810 standard.The UGV can be operated in both manual and semi-automatic modes. In the semi-automatic mode, the robot can autonomously navigate by traversing the pre-defined waypoints.

The robot has the capability to return to home automatically when the mission is completed.It is suitable for both indoor and outdoor operations and can be used by mounted and dismounted soldiers.The robot can be fitted with up to 20 mission kits based on the operational requirements. A 360° vision, high-definition day camera mounted at the front provides panoramic view, local situation awareness (LSA) and under-vehicle reconnaissance. A thermal imaging / infrared camera with uncooled detector allow operations in low-light / night conditions.The robot features a pusher actuator for mechanical action on suspicious objects, an audio intercom bi-directional communication system to receive operator voice and predefined sounds.

It is compatible with payloads such as CBRN detectors, lighting system, exploration and self-mapping kits, anti-IED tool kit, non-lethal grenade, and smoke generator together with anti-intruder and position-marking devices. Control station:The unmanned ground vehicle can be manually controlled by the operator from rugged personal computer or tablet or smart phones.Performance:The robot can reach speeds up to 15km/h and has an endurance of two hours. Its operation time can be extended by installing an additional external battery. The UGV can climb stairs and traverse through obstacles.

It is throwable and reversible up and downwards.It can collect information across a distance of 1km in open terrain conditions and up to 300m in urban areas.Field spying part:Wireless camera can be operated remotely for monitoring as well as controlling purpose. In the dark nights or dark places, this robot is capable of capturing videos, and then transmitting them remotely to a PC or TV by using wireless technology.This is to know about the status of the enemies around that area.

It monitors the area with a camera by moving the camera to various positions or places remotely by an android application.This uses microcontroller as the central processing unit, a Bluetooth modem to receive the command signal from the Android phone, an Android phone with a GUI application, a night vision wireless camera with remote area transmission capabilities, an IR LED for night vision lighting, a motor driver to drive a set of motors to control the vehicle movement and other miscellaneous associated components. The user can monitor the war field area by controlling the movement of the vehicle by an Android application. When the user touches the position command in the Android application, the signal from the system is received remotely through a Bluetooth modem in the robot, and is further transferred to the microcontroller as shown in the figure.The microcontroller is programmed in such a way that upon receiving corresponding signal from the Bluetooth, it sends the command signals to a motor driver that drives the set of motors to move the vehicle in the desired direction. And, also the wireless camera sends the video signals to a receiver station or unit, wirelessly, for monitoring purpose. Range matters.

Ruggedness matters. Mobility matters. A stuck robot is worth about as much as the dirty laundry it’s stuck in. this robot is easy to drive, nearly impossible to get stuck thanks to the end over end flipping motion, and able to clear multi-story structures by using the automatic climbing mode. It also can lay flat to inspect under cars or furniture and see at night with light and IR illumination. Other robots have external antenna that can easily break or tracks that get tangled in debris. If you want to get in, get a look around, and get out consistently, you need a robot Tactical Robot.  Camouflaging technique:Camouflaged technology based Wireless multifunctional device  having locomotion and navigates around the risk prone areas and tries to identify the intruders.

Various sensors are used to achieve camouflaging.PIR sensor:The PIR (Passive Infra-Red) Sensor is used to detect the changes made in the surrounding object by measuring the infrared levels made by the movement of object. The high signal of the motion of object is detected on the I/O pin. PIR sensor is a pyroelectric device. The PIR sensor is a device which generates electric charge when exposed to infrared radiation and is made of a crystalline material. An on-board amplifier is used to measure the changes in voltage generated that is obtained by the infrared on striking the object. Fresnel Lens is a special kind of filter used in this sensor which is used to focus the infrared signal onto the object.

The motion of the object is indicated by on board amplifier on rapid change of the ambient infrared signal. This PIR sensor has a single bit output having small size that makes it compatible to all micro-controllers of 3V & 5V operation with<100uA current draw.Colour sensor:To analyze the color of its environment, the color sensor is used. The colour sensor used provides small size, low cost, easily compatible. This color sensor is small in size and integrated on a small module making wiring easy and also emits precise information of the neutral color lighting of pure white. The operating principle of color sensor is simple.

Photo diode is used to generates signal after reacting with the color filter on receiving light reflected by ground. The generated signal is analyzed in terms of frequencies and then gives ground color.LED matrix:To display ground colours, 8×8 RGB LED matrix’s is being used. We used one matrix with one color sensor which allows it to create a uniform color zone. Besides, these LED matrix’s have many benefits such as pins in 2*16 sets make it easier for wiring, their lightening quality (the device is used for the purpose of reproducing a color rather than lightning up the environment), and a low power consumption.Metal detector:To detect the metal objects, Metal proximity sensor has been used. It will detect the object between 1cm to 7cm. On detection of any metal object, the Led will blink and the buzzer will be initialized.

The Principle of this metal sensor is the inductive oscillator circuit. The inductive oscillator circuit is used to monitor the current losses in coil occurred due to the high frequency. The metal sensor is designed for detecting the metal objects by detection of the Eddy current losses produced by high frequency. On detecting the metal object,the level of the output signal changes. The level of the change in supply current indicates the Output signal. Output current depends on the distance of the metal object. The flow of current will be maximum when the object is near to the coil or when the object is far the current will flow less through the searching coil.

The detector is beneficial in many ways like the detection range is up to 7cm, Range of operation varies according to the size of object, Power consumption is of 5V DC and 50mA,digital output having Active with logic “0” and full SMD design.On the whole we used a LED matrix (RGB) which can diffuse uniform colors, coupled to sensors that can precisely identify ground colors. This device is designed in such a way that it can reproduce the color independently at various areas each area being able to reproduce color with specific spots of the ground surface. References:https://www.alyarrobotic.com/micro-spy-a-robot/surveillance-robots/https://www.snopes.com/photos/technology/insectdrone.asphttp://mashable.com/2016/05/19/perching-robot-bee/#xKqYfEA968qGhttps://www.geek.com/gadgets/this-tiny-robotic-dragonfly-drone-only-costs-119-1533241/http://www.army-technology.com/projects/nerva-lg-mini-unmanned-ground-vehicle-ugv/
