1. INTRODUCTION

The tank demonstrates target obtaining, after, and focusing on abilities. These capacities show the basic advances behind the use of self-sufficiently controlled vehicles to tanks. The tank utilizes a blend of Xbee, Arduino, and Ipcamera to self-governingly track and at target. The Ipcamera utilizes a shading following project running, which the tank uses to track a moving focus from side to side. Prior to a full scale model is constructed, it is helpful to assemble a little scale model to demonstrate the innovation's ability. It is difficult to secure a genuine military tank to test the limit of the arduino, xbee, and the camera running the shading after venture, in achieving full independence. In building a little scale form of a potential model, these advancements can be shown to connect together effectively with the installed framework, and in addition give exact and powerful self-sufficient following. In effectively fabricating this little scale robot, the military would be persuaded into building a full scale model for a target tank.

1.1. Objective

The object of the project is to distinguish and track a moving objects and people. The following of the article is taking into image proccesing of camera vision instead of working on sensors. Self-sufficient tanks would be essentially advertised towards the military and national barrier. The idea of UGV bring useful advantages to soldiers and civilians in designated war zones. Self-sufficient UGVs can detect, track and strike targets by themselves. These vehicles have profited the military with the capacity to send these robots in front of units to look at territory they speak the truth to enter. The innovation modified into these vehicles then permits the warrior to spot adversaries that may be holding up to trap the unit. This alone can help recovery lives.The Project aim at enhancing public safety, enabling scientific research, protecting the environment.

1.2. Background

The primary occasion of present day apply autonomy showed up in 1948 when George Devol and Joe Engleberger made a mechanical arm. The two later made the first mechanical technology organization in 1956. In 1979, the Stanford Truck robot effectively crossed a seat filled room with no human help. It did this by utilizing a camera to take pictures and after that sent them to a PC for investigation. The robot could go at a rate of around one meter each 15-20 minutes, and soon thereafter it would then take pictures and reassess the environment. It did this by using a locally available PC to make the essential figurings. This PC is equivalent to today's microcontrollers. The principal genuine rough independent vehicle was the Terregater, which was made in 1984 for the main roles of street mapping and mine investigation. This was the first example where an independent robot was made for a particular modern capacity. The thought of an independent following robot is moderately new innovation. Robots have been around for quite a long time, yet having one that can basically think all alone has not been investigated until late improvements in microcontroller innovation. Late advancements in wireless advances have likewise took into account investigation into remote control and information exchange. Because of these components, enthusiasm for this field is starting to blast, particularly due to a late order put forward by the US military. Extra significance is being set on the space meanderers utilized by NASA. These new wanderers, particularly the ones right now on Mars, must have a self-ruling ability to help adjust to the landscape. There are numerous plans today that all give comparable capacities. This robot will be not quite the same as most on the grounds that it consolidates a wide range of segments to make up the last plan. As indicated by the Stanford Truck robot, cameras have been utilized on robots for more than 40 years. Different gadgets, for example, the self-cleaning sweeper utilization range discoverers to recognize questions before it keeps running into them. This venture is special on the grounds that it joins constant feature following by means of wireless, information exchange with wireless.

2.6. Pololu Dual VNH5019 Motor Driver Shield for Arduino

This shield makes it simple to control two high-control DC engines with your Arduino or Arduino-good board. Its double vigorous VNH5019 engine drivers work from 5.5 to 24 V and can convey a ceaseless 12 A (30 A top) per engine, or a consistent 24 A (60 A crest) to a solitary engine associated with both channels. These awesome drivers additionally offer ebb and flow sense criticism and acknowledge ultrasonic PWM frequencies for calmer operation. The Arduino pin mappings can all be altered if the defaults are not advantageous, and the engine driver control lines are broken out along the left half of the shield for broadly useful utilization without an Arduino. This engine driver shield and its relating Arduino library make it simple to control two bidirectional, high-power, brushed DC engines with an Arduino or Arduino clone. The board highlights a couple of vigorous VNH5019 engine drivers from ST, which work from 5.5 to 24 V and can convey a nonstop 12 A (30 A peak) per channel, and including draw up and security resistors and FETs for opposite battery insurance. It sends completely populated with its SMD parts, including the two VNH5019 ICs, as indicated in the photo to one side; stackable Arduino headers and terminal squares for interfacing engines and engine force are incorporated yet are not welded. This adaptable engine driver is proposed for an extensive variety of clients, from novices who simply need a fitting and-play engine control answer for their Arduinos to specialists who need to straightforwardly interface with ST's awesome engine driver ICs. The Arduino pin mappings can all be redone if the defaults are not helpful, and the VNH5019 control lines are broken out along the left half of the board for broadly useful utilization without an Arduino. This adaptability, alongside an alternative to control the Arduino straightforwardly from the shield, separates this board from comparable contending engine shields.

3. SYSTEM DESIGN

The tank which the item to be followed as a hued ball must be intended to work in an ordinary indoor environment, at room temperature. The robot can be physically guided to the objective range, in spite of the fact that it must be remotely controlled. Once the robot is inside of three feet of the objective, it must be equipped for having 360 degrees of turn to self-sufficiently discover the item utilizing a remote camera. This scope of movement obliges that the robot has a zero degree turn span. When the objective is gained, the robot must move to a most extreme separation of three feet from the article, and stay inside of that range for the term of the time.

3.1. Appearance/Maneuverability

Initial design ideas included using two palette, independent two motor, a tank design with treads. The two palette design would allow for each side of wheels to run off of one motor thus requiring two motors total. It would also have capabilities of speed that the other options might not.

3.2. Control

Concepts for controlling the robot include using a standard wireless joystick controller, a smart phone. The team decided to use a joystick controller to provide the interface between the robot and user. A smart phone app for control is also an attractive idea that would build on recent wireless technology. We believes that a possible future solution would be to use smart phone technology for complete robot control. Wi-Fi is another option for wireless communication, as has a much further range, and is especially efficient when transferring video data.

3.3. Tracking/Communication

For the camera which support video processing to make target tracking possible will found many open source libraries. There will many range sensors considered to determine distance from the tracked object and surroundings to avoid collision. Some options included radar, sonar, and ultra-sonic range finders. Radar has several negative aspects associated with it, including delays and interference. The Doppler Effect would also require special considerations based on the speed and direction of our moving robot. Ultra-sonic range finders give good accuracy and resolution, but require multiple on each side to be useful for object avoidance because of their small detection angle. Our solution was detecting object with using none of these components. We detect objects using colour of the object. What we offered is detecting green colour and tracking the object.

Figure 10 Figure 10

The RGB shading model relates nearly to the way we see shading with the r,g and b receptors in our retinas. RGB utilizes added substance shading blending and is the essential shading model utilized as a part of TV or whatever other medium that ventures shading with light.It is the fundamental shading model utilized as a part of PCs and for web illustrations, however it can't beused for print creation. Secondary colours of RGB are framed by blending two of the essential hues and barring the third shading. Red and green consolidate to make yellow, green and blue to make cyan, and blue and redform red. The mix of red, green, and blue in full force makes white.

3.4. Building a Body

In deciding the frame and look of the robot, some options included buying a premade vehicle, building one from the ground up, or doing a combination of both. Buying a premade body seems like a cheaper option, but limits the size and design type. Building one from the ground up would give more freedom in design, but appears to be more costly. Doing a combination of both would limit some design aspects, but still give some freedom in the overall style of the body. Buying a frame with palettes and motors would ensure that parts run smoothly together, but would allow for custom design of the outer shell.
