ABSTRACT There are many types of pesticide sprayers are available. But mostly used sprayers are battery-powered backpack type sprayer, hand-operated backpack sprayer, petrol-powered backpack sprayer which is used by farmers because it is cheaper, easy to use, less maintenance, and low cost. With the help of these types of a sprayer, farmers spray pesticides on their farm, but the operational cost and time consumed to spray are high. Also, the farmer who is spraying pesticides is affected by pesticides whereas some pesticides are dangerous to human health, and also faces lumbar pain due to the weight of equipment. These method uses lots of time and affects human health. This paper suggests vehicle/robot which will reduce the operational cost and also saves time. Also saves human from harmful pesticides. Keywords: Automatic pesticides sprayer, Pesticide spraying robot, Color based navigation.

INTRODUCTION
India is a country where more than 65% of people live in a rural area and the main source of their income is farming, directly or indirectly. More than 65% of people in India are connected with farming directly or indirectly, instead of that we are not producing the crop of which we having the capacity to produce. The reason behind this is the Indian farmers are not using technology very well. So we have to make vehicles/robots that can help them to save their time and money to increase the production rate and their profit. We have to form economic machinery so farmers can buy it as per capita income of our country’s farmers are low and our country per capita income is low when compared to other countries. The present scenario in the agricultural field in India related to the sprayer is that farmers are using hand operated sprayer or battery/petrol-powered sprayer. According to the idea in our project, we are making a small 4-wheel kart or vehicle which is electronically operated by colors fixed in the ground which runs on a DC power source. One vertical arm is attached at the center of the vehicle and one horizontal arm at top of the vertical arm. The nozzle is fitted to those arms in order that it can spray pesticides on both the edges. As more number of nozzle is there hence spraying is done rapidly and time and money are saved.

METHODOLOGY
The machine consists of the main body frame, battery, DC Motor, Nozzles, Pipes, Wheels, Tank, Arduino UNO, Buzzer, Color sensor, Float sensor, LCD, Relay, Relay driver, Ultrasonic sensor, and DC Pump.
Assembly This is a four-wheel-drive machine. All four wheels are individually driven by DC Motor. The frame is made up of mild steel. A vertical arm is attached at the center of the backside mainframe, carrying a horizontal arm. The nozzles are fitted to the pipes which in the center of the backside mainframe. The horizontal arm is movable on the vertical arm. The pesticide storing tank is kept at the center of the body. The battery is kept at the front side and DC Pump is kept at the backside of the tank. this machine is powered by DC Battery. DC Motors are directly attached to the wheels. Also, the DC Pump runs on the battery.
Working The vehicle is guided by colors that are fixed manually in the ground. The Color sensor detects the color and sends a command to Arduino. The Arduino commands the robot about the direction. If the color sensor detects RED, BLUE, GREEN, BLACK colors it turns 90 degrees right,90 degrees left, starts/stops spraying, stops the vehicle respectively.
