ABSTRACT
Many advances in technology have made the agriculture business a much less labor intensive industry to be a part of. If we think back even only 50 years, farmers were just beginning to incorporate technologies into their farming techniques. It has been said that individuals that are involved in the farming industry are some of the least susceptible to change. They are very set in the ways of those came before them. When we take a look at the farming industry now, we can see that this is rapidly changing. Farmers are looking for new ways to implement technology to cut costs and reduce labor hours. Also a wireless camera with voice and image transmission is interfaced to the kit.
One of the ways that farmers are beginning to explore new technologies in farming come from the autonomous tractor. The RF based robot is something that is very new to the agriculture industry, but is quickly gaining popularity from agriculture research companies around the United States. These robots are described by Farm Industry News as a tractor that drives its solve with a computer in control. Although still in the research phase of development, autonomous robots are rapidly becoming more of a reality than an idea.
When the robot is moving on a surface, it is controlled by a RF remote. This can be moved forward and reverse direction using geared motors of 60RPM. This robot can take sharp turnings towards left and right directions. Also this robot can be move the plotter up and down for saw the land. And this robot can rotate the seeder box in forward and reverse directions for sprinkling the seeds on the land. This project uses AT89S52 MCU as its controller.
The RF modules used here are STT-433 MHz Transmitter, STR-433 MHz Receiver, HT12E RF Encoder and HT12D RF Decoder. The three switches are interfaced to the RF transmitter through RF Encoder. The encoder continuously reads the status of the switches, passes the data to the RF transmitter and the transmitter transmits the data.
