AGROBOT

Electronics Engineering

Compared to spraying pesticides manually outdoors,the environment has a high temperature,humidity for operating the spray work in green-house or in farms.In order to protect labourer and reduce labour intensity,we have develope a prototype of pesticide spraying robot specially used in the greenhouse and farms.ROBOT is controlled with a ARM7 controller.Designing of latest inverted ROBOT which will be controlled using an REMOTE.We are developing the remote buttons and commands in the hardware by which we can control robot motion using RF communication to interface controller and remote.Controller can be interfaced to the RF module through UART protocol. According to commands received from remote the motions can be controlled. The consistent output of robotic system along with quality and repeatability are unmatched.Although the productivity of prototype is not quite efficient,the robot still meets the requirements of pesticide spraying in farms without human operators.The robot is equipped with RF receivers, which decodes and control it. The transmitting and receiving modules are constructed using microcontroller.This project is divided into two modules.One is transmitting(Remote)and other is receving module(Robo).The tramsmitter is built by 89C2051 Controller.The data is modulated and transmitted by RF module.The movement of Agrobot is designed by DC motor.The data of sprayed pesticide is stored in memory using RTC and it is displayed on LCD.The required power supply is drived from battery.
