Abstract - This project is for the design, development and manufacture of robots that can spray water, and these entire systems of robots run on batteries and solar energy. With more than 40% of the world's population choosing agriculture as primary occupation, interest in developing self-driving vehicles in agriculture has grown in recent years. The vehicle is controlled by a relay module and Bluetooth. Input allows users to interact with robots in a way that is familiar to most people. The advantage of these robots is hands-free operations. In the field of agricultural, concepts are being developed to investigate whether multiple small autonomous Robots are more efficient than traditional large tractors or human power. Technology has been developed in various fields, including agriculture. In agriculture there are many automatic machines designed to save human energy, labor and most importantly time, but they are neither efficient nor economical. Therefore, we developed a Smart Phone Operated Water Spraying robot (SPOWSR) operated by a smart phone.

Key Words: SPOWSR, Robotic Vehicle, Irrigation, Autonomous, Sensors, Automation, Bluetooth.

1. INTRODUCTION

AgricultureisthebackboneofIndia.Today,Indiarankssecondintheworldforagriculturalproduction.Specialtyvehicles playanimportantroleinmanyareas,includingindustrial,space,medical,and militaryapplications.TheRoboticVehicles isgraduallyincreasingproductivityintheagriculturalsector.SomeofthemajorproblemsinIndianagricultureareskilled labour,scarcityofwaterresourcesetc.Automationtechniqueshavebeenusedinagriculturetoovercometheseproblems. Agricultural automation can help reduce labour for farmers. In doing so, robots are developed to be able to concentrate efficiently and are also expected to perform operations as needed. The proposed idea implements a Robotic vehicle to perform the function of water spraying. This function can be carried out our Robotic Vehicle. The idea of using robotic technology and automation in agriculture is very new. In agriculture, the opportunities for robotic productivity are immense,androbotsarecominginmanyformsandincreasingnumbersonthefarm.

2. PROJECT OBJECTIVES

The motivation for this project came from countries whose economies are based on agriculture and where climatic conditionsleadtolowrainandwatershortage.Farmerswhoworkinthefieldsrelyonlyonrainandwaterwellstoirrigate theland.Eveniftherearesubmersiblewaterpumpsonthefarm,manualinterventionbythefarmerisrequiredtoturnthe pumpsonandoffasneeded.Thegoalofthe projectistoproperlysprinklewateraccordingtotheneedofplantswhichis subject to change in different seasons. For instance, in summer due to increased temperature plant need more water, However, in winter the need of water is less. This project will help make plant care easier. The Water Spraying Robotic Systemservesthefollowingpurposes:

To meet growing demand, farmers must increase harvest efficiency through rapidly advancing technology. This system was developed and implemented to solve the irrigation problem. Farmersusuallyrequirealotofmanpowertoirrigatelargeareasatonce.However,asmartphone-operatedwaterSpraying robot(SPOWSR)isasystemthatfacilitateslandirrigationwhenneeded.
