GPS GMBot

This project investigates how the Global Positioning System (GPS) can be used to guide an autonomous vehicle. The project involves the design and implementation of a robot that is capable of guiding itself from one point to another. A Garmin GPS receiver module along with a Rabbit microcontroller and serial servo controller are used to guide a 1/10th scale car. The GPS receiver provides latitude and longitude information at 1 Hz. A proportional control system is implemented in the microprocessor. The serial servo controller is used to control a servo for steering and a motor for acceleration and deceleration. The vehicle travels at 10 M.P.H and is capable of reaching its desired location to within +/-6 feet.
