Automatic control of ground vehicles has been a research objective for many years. Such control has many potential applications, including development of smart roads that automatically pilot vehicles to the destinations their users select; control of construction vehicles that build roads automatically; and control of vehicles operating in hazardous environments. Satellite-based controllers also might allow farmers to do things that are impossible or impractical manually, such as enabling a single driver to operate a convoy of several tractors at the same time. A spiral pattern would allow a farmer to plow a large field continuously, without wasting time making U-turns at the end of each set of rows, but it is very difficult for drivers to do. Automatic guidance of agricultural vehicles like tractors in the mechanized farming practice has taken the attention of Agricultural engineers. For this to be truly practical on the farm, it should be economical, simple to operate, and entirely contained on the vehicle. Steering automation has been implemented successfully on agricultural vehicles on the basis of analogue-type components, i.e. sensors, controllers, and actuator elements. The paper describes the different features of automatic navigated vehicles and summarizes the success stories in developing countries.
