This kind of tilt detection robot can be helpful for the civil engineers in the construction works it helps to detect the slopes in the beamers, floors etc. which can be easily done without any manual interference.

Human being detection wireless remote controlled robot project report is useful for electronics and communication students. In exiting fast growing technology robotics applications are playing important role in handling tough tasks where humans cannot reach there are many applications in military, chemical, mechanical companies..etc. Human Detection Robot Project are designed to reach places where humans cannot reach like in military it is tough task to remove bomb in that cases robots are used. Similarly there are many applications where this systems are used.

This project is a prototype boat that can travel in water. The direction of the robot can be controlled by DTMF. This can be moved forward, backward direction. Also this robot can take sharp turnings towards left and right directions using DC Motors. This project uses AT89S52 MCU as its controller. This project uses DTMF technology for controlling Robot in a way such that near the controlling side we are provided with any type of communication device such as a mobile phone or a landline. Now coming to the other side we are provided with the mobile phone only because a landline cannot move accordingly with the movement of the boat. In the mobile phone we allot the number keys as our direction movements for the Robot to move. Now when we dial the numbers in the mobile phone from the controlling side then it automatically recognizes which number has been recorded and it follows with the corresponding next step to be taken i.e., movement of the robot in water. This Project uses DTMF Decoder which is controlled by a battery and in turn is connected to the mobile phone. This is controlled by the controller and is again connected to the driver circuit for driving the motor. This project uses battery. This project is much useful for mines detection and Oceanic Research Applications

This project demonstrates the research and implementation of voice automated fire extinguisher vehicle. The vehicle is controlled through connected speech input. The language input allows a user to interact with the robot which is familiar to most of the people. The advantages of speech activated robots are hands-free and fast data input operations. The speech recognition system is trained in such a way that it recognizes defined commands and the designed robot navigates based on the instruction through the Speech Commands. The medium of interaction between humans and computers is on the processing of speech. The complete system consists of three subsystems, the speech recognition system, transmitter section and the receiver section (on vehicle) .We have studied the various factors such as noise which interferes speech recognition and distance factor. The results prove that proposed robot is capable of controlling fire, avoiding obstacles and understanding the meaning of speech commands

This project outlines the strategy adopted for establishing two kinds of communications; one for wireless communication between a mobile Robot and a remote Base Station, another for serial communication between a remote Base Station and a GUI Application, PC. TekBot is a low cost mobile Robot built by Oregon State University which in its current version requires wired communication. Our aim is to be able to command and control the Robot wirelessly by the GUI Application. The principle task of this project was to program the AVR microcontroller interfaced to a radio packet controller module (operating at a frequency of 433 MHz) which would enable us to wirelessly control the Robot. The communication protocols dealing with transmission and reception of data and wireless control of the TekBot have been successfully implemented

Today human-machine interaction is moving away from mouse and pen and is becoming pervasive and much more compatible with the physical world. With each passing day the gap between machines and humans is being reduced with the introduction of new technologies to ease the standard of living. Gestures have played a vital role in diminishing this abyss. In this paper, a rigorous analysis of different techniques of “Human-Machine Interaction” using gestures has been presented. Gestures can be captured with the help of an accelerometer, however, with the evolution of smart phone its independent usage has been rendered useless. This paper analyses the motion technology to capture gestures through an android smartphone with an inbuilt accelerometer and Bluetooth module to control the kinetics of a robot. The signals of the Bluetooth Module are controlled by the Microcontrollers

The aim of this project is to build a vehicle that can be controlled by using wireless MEMS (Micro Electro-Mechanical Systems) based accelerometer. This consists of a remote control that wirelessly transmits data using RF technology to the remote vehicle to move in any direction. The accelerometer will be mounted on a steering plate (remote control), such that if the steering plate leans in some direction then the robot vehicle moves in that direction. If the user wants to move the robot forward he can lean the steering plate forward and backward for reverse. To turn left or right user need to turn the steering plate toward left or right respectively.

When we say voice control, the first term to be considered is Speech Recognition i.e. making the system to understand human voice. Speech recognition is a technology where the system understandsthe words (not its meaning) given through speech. Speech is an ideal method for robotic control and communication. The speech recognition circuit we will outline, functions independently from the robot’s main intelligence [central processing unit (CPU)]. This is a good thing because it doesn’t take any of the robot’s main CPU processing power for word recognition. The CPU must merely poll the speech circuit’s recognition lines occasionally to check if a command has been issued to the robot

The project aims in designing a system which is capable of controlling the boat directions and also the camera direction present in the boat intellectually using a wireless Zigbee remote. The video images thus recorded can be seen live on TV. It is a very lowcost survey line system used to monitor a larger area using number of cameras. The entirearea can be completely automated such the direction of the cameras can be controlled bya unique wireless remote. Since the frequency we are using is of radio band so that it can be also controlled from a very larger distances. Zigbee is a PAN technology based on the IEEE 802.15.4 standard. UnlikeBluetooth or wireless USB devices, Zigbee devices have the ability to form a meshnetwork between nodes. Meshing is a type of daisy chaining from one device toanother. This technique allows the short range of an individual node to be expandedand multiplied, covering a much larger area.

A land mine is an explosive device designed to be placed on or in theground to explode when triggered by an operator or the proximity of avehicle, person or animal. The name originates from the practice of sapping, where tunnels were dug (much like mining) under enemyfortifications or forces. These tunnels ("mines") were first collapsed todestroy fortifications above, and later filled with explosives and detonated.Landmines generally refer to devices specifically manufactured for this purpose, as distinguished from improvised explosive devices.

<p> The objective of this paper is to control the railway tracks by using anti-collision techniques. The model of railway track controller is designed by using 8952 micro controller to avoid railway accidents. When we go through the daily newspapers we come across many railway accidents occurring at unmanned railway crossings. This is mainly due to the carelessness in manual operations or lack of workers. And also the collision of two trains due to the same track. This model is implemented using sensor technique. We placed the sensors at a certain distance from the gate detects the approaching train and accordingly controls the operation of the gate. Also an indicator light has been provided to alert the motorists about the approaching train.

Improving the quality of life for the elderly and disabled people and giving them the proper care at the right time is one the most important roles that are to be performed by us being a responsible member of the society. It’s not easy for the disabled and elderly people to maneuver a mechanical
wheelchair, which many of them normally use for locomotion.Hence there is a need for designing a wheelchair that is intelligent and provides easy maneuverability. In this context, an attempt
has been made to propose a thought controlled wheelchair, which uses the captured signals from the brain and eyes and processes it to control the wheelchair. Electroencephalography (EEG)
technique deploys an electrode cap that is placed on the user’s scalp for the acquisition of the EEG signals which are captured and translated into movement commands by the arduino microcontroller
which in turn move the wheelchair.

A robot is designed and constructed with associated electronic circuits to move into an unknown location and transport the details of that unknown area to a home place. The Robot will have inbuilt sensors and cameras to achieve this. The system is made more useful by introducing artificial intelligence to it. By artificial intelligence, we mean designing the robot is such a manner that in situation which require decision making, the robot identifies the presence of the obstacle, alerts the user and moreover awaits instruction from the user for the further action. Other condition, which the robot can determine, is presence of fire. I.e., high temperature and presence of metals in vicinity.

The legitimate time expense of transforming and information transmission is significantly decreased. This framework can possibly attain to elite in recognizing alive people in crushed situations moderately speedily and cost efficaciously.The discovery relying upon various variables, for example, the body position and the light force of the scene.

The Black Box in the cockpit is only been elemental in recording the audio part, happening in cockpit and apparently the control station at the ATC obtains the deferred data as explained by Pilot and thus there is no automated system to obtain the instantaneous reports happening there. Moreover if the Pilot the asks for the replay of the process that had gone through, in his past-journey span while on-board and still at traveling, it’s not possible for the Base Station to relay the Replay of the information. Proposed System: Here we propose a system of automated information to be available to the Base, and also the instantaneous Relay of the Alert Levels and the Replay of the course of journey, the pilot had covered till the time back to him. Implementation: We split the project into 3 parts: • The Pilot’s side. • The External Hardware implementation. • The Control Base at ATC (Air-Traffic Controller).

A robot is an electro-mechanical device that can perform autonomous or reprogrammed tasks. A robot may act under the direct control of a human (eg. the robotic arm of the space shuttle) or autonomously under the control of a programmed computer. Robots may be used to perform tasks that are too dangerous or difficult for humans to implement directly (e.g. nuclear waste clean up) or may be used to automate repetitive tasks that can be performed with more precision by a robot than by the employment of a human (e.g. automobile production.) Abstract: This project aims at designing a robot, which has freedom of movement along all the 3 axes and its motion is controlled by means of wheels. The user can control the movements using a Cellphone from a remote place. The system is made more useful by introducing artificial intelligence to it. By artificial intelligence, we mean designing the robot is such a manner that in situation which require decision making, the robot identifies the presence of the obstacle, alerts the user and moreover awaits.

Windmill a mill that is powered by the wind and that extracts usable energy from winds INTRODUCTION Generating power is of great importance in today’s world. Due to the pending exhaustion of fossil fuels, it is crucial to develop alternative energy sources. Energy-converting windmills are capable of producing significant amounts of electricity worldwide, an attractive alternative because wind is a renewable resource. The technologies behind wind energy converters still have much room for improvement in efficiency. Wind, as an energy input of windmill systems, can be given by two parameters: speed and direction. Because the energy output of the windmill is determined from the input, it is important to be able to understand the stochastic fluctuations in wind Wind behavior will be approximately constant over long periods of time, but for any given period wind can be extremely variable in speed and direction. Parameters of the wind that is necessary for The Wind Turbine predicting turbine performance are mean wind speed, directional data, short-term variations (gusts), long- term variations and height variations A windmill is an engine powered by the wind to produce energy, often contained in a large building as in traditional post mills, smock mills and tower mills. The energy windmills produce can be used in many ways, traditionally for grinding grain or spices, pumping water, sawing wood or hammering seeds. Modern wind power machines are used for generating electricity and are more commonly called wind turbines

Wired communication, also known as tethered communication is the easiest way to control a robot where the system is physically connected to a hand held controller or a computer through a cable or wire. Most battle robots are wired control as most of the control is in the handheld device including the power source. This makes the robot less complex with tighter control. The disadvantage of wired control is the length of control. The maximum length of control is equal to the maximum length of the wire. In this technique the robot is still physically connected to a controller with wires. However a micro controller on board receives the signal from the controller and subsequently controls other peripherals connected to the robot. The controller can be a joystick, switches, keypad or even your computer. If you are using a computer, you can use a serial I/O connection, parallel I/O connection, USB and if you prefer using internet to control your robot, you can connect a router. There are different protocols for each of these controls, but most of them are easier to design and implement if you prefer a wired control.

The robots that are controlled by interfacing with a personal computer are called as computer controlled robots. A computer is an integral part of every robot system that contains a control program and a task program. The control program is provided by the manufacturer and the controls of each joint of the robot manipulator. The task program is provided by the user and specifies the manipulating motions that are required to complete a specific job.

In this paper, the authors extinguish fire using robot which is remotely controlled through wireless. The robot can move through any path whose motion is controlled through the Wi-Fi network using buttons interfaced by a software program. When the robot faces a fire then it is made to extinguish the fire with the help of pump motor connected to a water tank mounted on its body. PC works as a remote to control the motion of the robot either to move it forward or backward and the motion of the water pipe up and down of the robot through which it throws water to extinguish the fire.

In the near future, the usage of a mobile robotshould become a common practice anywhere and a spoken language is a convenient interface for commanding such devices. Therefore, the development of an interface between human and robot is vital. Herewith, we describe how this was successfully implemented for a Kobuki Robot trough an Android device for commanding the robot´s movements according to the human spoken instructions.

This paper introduces an intelligent parking guidance and information system with ARM7 microcontroller. The parking problem in big cities, especially the mega-cities, has become one of the key causes of the city traffic congestion. The Parking Guidance and Information System (PGIS) is considered to be an effective way to improve parking situation. In general parking systems are designed by using different sensors like IR or ultrasonic sensors. By using these sensors they identify whether parking slot is free or it already contains car. But actually these sensors are not used for detecting particularly car they can detect any object. .By using image processing technique it identifies car only or if any object other than car is at parking slot it don’t considered that slot is booked. In this paper we also introduce an important feature like fetching the above said status of the parking slot on the web or Internet and status can updated for particular time. In this way the car parking system is more easier and flexible for the person to view and book the slot from anywhere. It is done by using Image Processing, Embedded Linux, ARM7 ,GSM.

In this implementation of Defense security systems .When a person or motor vehicle enters a monitored area, PIR motion detectors are commonly used in conjunction with different parts of the war field. When someone enters secured places, immediately it will send an indication to the control room section through wireless communication and is indicated to the control room through alarm . The concerned people can understand that an eventuality has happened in the host section. At the same time web camera connected to the microcontroller keeps on capturing what is going on there at the host place and saves it into the computer. When the security people in supervisory room, get an indication to the host section by alarm, they log into the host section computer through wireless LAN, and view all information of the war field section images by PC and can operate the weapons if the entered people were opponent person. Sectors based on PIR detectors, ultrasonic sensors and also communicate to the Control room through wireless communication by means of encrypted data and then from the control room they can able to monitor what’s happening in the war field and supervise from the control room itself when signal is sent on detection of human by pir sensors a alarm is buzzed in control room thus reducing work load.

This paper presents the implementation of wireless arm robot using Programmable System on Chip (PSoC) and virtual Instruments programming using LabVIEW graphical language. The wireless control has been implemented with Zigbee protocol. Some of the main features of Zigbee protocol are to establish wireless communication medium between the arm robot and the PC controller. The hardware system is based on the PSoC microcontroller interfaced wirelessly with LabVIEW via a Zigbee module. The user can send the control instructions to the robot from the PC by using the Zigbee Protocol. As soon as the instruction is received by another Zigbee at the receiver end, PSoC microcontroller will come into action and will start the motor drivers so that the Robot starts moving as per the instructions sent by the user/ operator from PC. In addition to the above qualities of the arm robot, its intelligence is further upgraded in this design by making use of a color sensor to identify and handle the required color objects

Vast amount of energy is available within the core of sun. The energy that is received from sun in an hour is more than that is consumed by us in a year . If human race is able to capture even 1% of the total energy which sun delivers then we can cater the need of our race for decades. Efforts are continuously being made to capture as much energy as we can in order to store most of the energy which se are getting. In this paper a device called solar tracker has been discussed. Solar panels give maximum output when the plane of the solar collector is normal to incident radiations. The system discussed in this paper uses a PSoC device to control a small model of solar tracker. Voltage across the solar panel and a photoresistor is fed as an input to the PSoC to be processed and the output is fed to the geared DC motor.

In the rapidly flourishing country like ours, accidents in the unmanned level crossings are increasing day by day No fruitful steps have been taken so far in these areas. our paper deals with automatic railway gate operation (i.e.,) automatic railway gate at a level crossing replacing the gates operated by the gatekeepers, It deals with two things, Firstly it deals with the reduction of time for which the gate is being kept closed and secondly, to provide safety to the road users by reducing the accidents. By employing the automatic railway gate control at the level crossing the arrival of the train is detected by the sensors placed near to the gate. Hence, the time for which it is closed is less compared to the manually operated gates. The operation is automatic; error due to manual operation is prevented. Automatic railway gate control is highly microcontroller based arrangements, designed for use in almost all the unmanned level crossing in the train

The project aims designing a robot which is capable of detecting land mines in its path and alerting through alarm system. Also, the robot is operated through a remote made using RF technology. The advent of new high-speed technology provided realistic opportunity for new robot controls and realization of new methods of control theory. This technical improvement together with the need for high performance robots created faster, more accurate and more intelligent robots using new robots control devices, new drivers and advanced control algorithms. This project describes a new economical solution of robot control systems. The presented robot control system can be used for different sophisticated robotic applications. RF Communication ranges in between 30 KHz to 300 GHz. RF communication works by creating electromagnetic waves at a source and being able to pick up those electromagnetic waves at a particular destination. These electromagnetic waves travel through the air at near the speed of light. The wavelength of an electromagnetic signal is inversely proportional to the frequency; the higher the frequency, the shorter the wavelength.

The main objective for the LawnBot group is to design a lawn mower that incorporates all of the features from various types of lawn mowers, plus more. The group will create a remote control lawn mower that utilizes each of the benefits, creating a safe, reliable and user friendly lawn mower. The project was done in two different stages. The first stage the group completed was the Remote Control Lawn Mower. The second stage of their project was creating an Autonomous Lawn Mower, the LawnBot. The remote control lawn mower has been designed and built by many engineers throughout the years. There are many variations of the remote control lawn mower, as people across the nation have attempted to advance the basic lawn mower by implementing the remote control aspect. The Autonomous Lawn Mower was a lot more difficult to design and build. By integrating hardware and software, the students found just how much technology can be used to develop an outstanding project. The group went a step further by creating an even safer version of the mower. In addition, the autonomous version is also much more convenient for the user.

The main aim of this embedded application is to design a PC controlled Robot which can detect live humans and transmit the location details wirelessly. It can also be used in war fields and places where disaster has occurred. Human detection is also required in hazardous sectors like boilers, reactors where only authorized person can enter. The live body sensor in this project is a special type of sensor known as PIR sensor. Any alive body with a temperature above absolute temperature emits radiations which are invisible to the normal eye. It senses these passive infrared rays to detect the live human. Human identity is carried out using a Human live detection sensor. The PIR sensor is used to detect the motion in any kind and will inform to micro controller. In this project we are using GSM based wireless system for the efficient communication. If the micro controller unit receives the detected signal, it will send a message through GSM modem. The GPS receiver receives the Longitudinal and latitudinal value when the system detects the movement of the human body it sends the location details to the stations using GSM modem.

The use of mobile robots is growing in manufacturing facilities, hazardous materials handling, etc. Usually, several sensor systems are used in combination. The task of combining the information into a usable form, suitable for making navigation decisions, is known as sensor fusion. In this paper, the navigation system built on a mobile robot operating in a warehouse is presented focusing on the sensory system used. Hybrid navigation system that combines the perception and dead reckoning is used and gives satisfactory operation. A microcontroller system is designed to control the navigation of a mobile robot while avoiding obstacles. A system of 24 ultrasonic sensors was designed and the operation algorithms were described. The encoder and the ultrasonic sensors used are presented in detail together with the navigation system designed based on their operation.

Visiable Light is a robot that can sense and follow light. A user can shine a flashlight at its front and Light Rover will respond by following the light source. Light Rover uses a microcontroller for processing the sensor readings and responds by controlling the motors. The robot is designed with two sensors in mind, a left and a right. So when more light is detected on the left side, the robot will move towards it by rotating the right motor forward and the left motor backwards. The robot will know to move forward when both sensors receive about the same (by a margin we specify) amount of light. The robot has two bipolar motors attached to front wheels of the robot. While rear wheels do not have any motor attached to them. The robot has two sensors fixed at its front panel separated by sufficient distance. It has a power supply & microcontroller circuitry placed inside the Light Rover.
We wanted to build a sensing light robot because microcontrollers are natural devices for sensing and responding to events.

Robots which can perform desired tasks in unstructured environments without continuous human guidance. Many kinds of robots are autonomous to some degree. Different robots can be autonomous in different ways. A high degree of autonomy is particularly desirable in fields such as space exploration, where communication and delays and interruptions are unavoidable. Advanced Robotic Pick And Place Arm And Hand System projects main idea is to develop a application which can handle tough tasks like bomb disposing and many other situations where human being can not reach. Control of the robotic arm has been achieved successfully by using servo motors or dc motors. The microcontrollers implement inverse kinematics algorithms and implement position control on the motors. The motors are actuated using the internal PWM channels of the microcontroller and MOSFET based power amplifiers or power transistors or driver circuits. The robotic arm also has the provision of being controlled. The end effecter is a two finger gripper. The robotic arm has a load bearing capacity of around 500gms. The device has its own in-built logic and all the movements of the device are controlled by the motors. The operating speed of the pick up arm can be varied to suit the requirement.
For a robot it is obviously important that it can operate from batteries. Since the microcontroller runs with 5V the motors also must work with 3-5V. They must also not take too much current as the batteries and the control circuit will get too big and heavy. For this design we use an integrated motor driver chip, called l293d. The l293d motor driver chip can drive peak. All the logic is implemented in the software. That means by changing the software you can change almost everything as you like. The good thing about this robot is that the hardware is somehow generic: It's basically 2 motors attached to a microcontroller

The work is designed to develop a pick and place robotic arm vehicle with a softcatching gripperthat is designed to avoid extra pressure on the suspected object (Like Bombs) for safetyreasons. The robotic vehicle is android application controlled for remoteoperation. At the transmitting end using android application device, commands are sentto the receiver to control the movement of the robot either to move forward, backwardand left or right etc. At the receiving end four motors are interfaced to the microcontrollerwhere two of them are used for arm and gripper movement of the robot while the othertwo are for the body movement of the vehicle. The main advantage of this robot is its softcatching arm that is designed to avoid extra pressure on the suspected object for safetyreasons. The android application device transmitter acts as a remote control that hasthe advantage of adequate range, while the receiver end Bluetooth device is connectedto the microcontroller to drive DC motors via motor driver IC for necessary operation.Remote operation is achieved by any smart-phone/Tablet etc., with Android OS; upon aGUI (Graphical User Interface) based touch screen operation

The study of the model controlled by voice and sensor control board. The model is built by utilizing normal fueled controller; it has voice acknowledgment, programmable terminal and coherent elevator program, which interface every one of them. The model can be effectively reconstructed keeping in mind the end goal to have different working administrations and consequently is suitable for preparing understudies with the expansive computerization specialization. Displayed framework could be utilized as a part of the elegant house ventures and, particularly for disabled people. The change of the surely understood DTW (Dynamic Time Warping) calculation was utilized. The arrangement of voice charges comprised of eight Lithuanian words (floor number, go, stop) and two expressions (welcoming and farewell). In this project we implement speech recongnization system and we hardware like Micro controller, stepper motor and regulator power supply. The speech recognition system is main part of this project. Speech recognition system provides the communication mechanism between the user and the microcontroller based control mechanism of elevator

This project is designed with micro controller, encoder, decoder, RF transmitter and receiver, bomb detector, deriver circuits, analog with motors and robot model. Bomb detector is just act as metal detector which detected any metal in the required areas. Because the bombs made with metals. The bomb detector is attached in the topside of the robot with an antenna. Robot movements are controlled remotely. Transmitting section consists of keyboard, encoder and RF transmitter. The keypad is the set of keys in which each one controls the robot in a directon such as forward, reverse, left and right. When any one key is pressed the corresponding signals are encoded in the encoder circuit and given to RF transmitter section in which encoded signals are modulated with carrier signal and transmitted through the RF transmitter.

What we present here is an elementary robotic land rover that can be controlled remotely using primarily the RF mode. The RF remote control has the advantage of adequate range (up to 200 metres with proper antennae) besides being omnidirectional. On the other hand, an IR remote would function over a limited range of about 5 metres and the remote transmitter has to be oriented towards the receiver module quite precisely. However, the cost involved in using RF modules is much higher than of IR components and as such, we have included the replacement alternative of RF modules with their IR counterparts for using the IR remote control

Main idea is to implement security system for detecting leakage of gas in closed environment. In this project gas leakage is identified by using sensors which works only in closed environment. In present situation there are many cases related to gas leakage which cause innocent people lives and property damage. Implementing this application can be useful for companies, houses, which can save lives of people. We use 8 bit microcontroller to perform the desired task by interfacing Gas sensor, Buzzer and LCD to display. The output of the Gas sensor is in analog form which can be converted into digital form using MCP3201 which is an ADC (Analog to Digital Converter). Initially when there is a leak the gas sensor detects it and gives voltage related to the amount of gas that is getting escaped from the apparatus. We create a set-point to the microcontroller so as if the Gas sensor gives the output above the set-point the controller drives the buzzer ON as an indication to the user.

The research on autonomous miniature flying robots has intensified considerably thanks to the recent growth of civil and military interest in Unmanned Aerial Vehicles (UAV). This paper summarizes the final results of the modeling and control parts of OS4 project, which focused on design and control of a quadrotor. It introduces a simulation model which takes into account the variation of the aerodynamical coefficients due to vehicle motion. The control parameters found with this model are successfully used on the helicopter without re-tuning. The last part of this paper describes the control approach (Integral Backstepping) and the scheme we propose for full control of quadrotors (attitude, altitude and position). Finally, the results of autonomous take-off, hover, landing and collision avoidance are presented.

The project is designed to control a robotic vehicle with a touch screen display unit for remote operation. The touch screen remote control is used at the transmitting side to transmit RF control signals. At the receiving end, a pick n place robotic vehicle is used to respond to those signals and perform the task.

The objective of this paper is to minimize human casualties in terrorist attack such as 26/11. The combat robot [1] has been designed to tackle such a cruel terror attacks. This robot is radio operated, self- powered, and has all the controls like a normal car. A wireless camera has been installed on it, so that it can monitor enemy remotely when required. It can silently enter into enemy area and send us all the information through its’ tiny Camera eyes. This spy robot can be used in star hotels, shopping malls, jewellary show rooms, etc where there can be threat from intruders or terrorists. Since human life is always precious, these robots are the replacement of fighters against terrorist in war areas.
