It will not be used for heading information as GPS heading is almost completely worthless at slow vessel speeds. GlobalSat BU-353 USB GPS - The GPS will be used primarily to provide position, course to steer and distance to waypoint. Parallax USB Servo Controller - This will be used to control the boat's propulsion motor(s) and rudder(s). It supports a wide variety of hardware (servo controllers, GPS sensors, serial interface, etc.) and provides a simple interface for making them work together. RoboRealm - This very cool software is really a key element to the whole system. Windows XP - Mostly because of the wide range of free tools and info available for it. Probably over kill for the task, but I happen to have one. For this first iteration of the project I hope to use all off the shelf components, the only customization will be some custom code I will need to write. The objective of this project is to design a very small boat ( roughly 1 meter LOA ) that will be capable of autonomously traveling a preset survey grid to produce a sonar bottom scan. The following are some of the components I hope to use to assemble this platform. I've got a couple ideas that I want to explore and need a suitable platform to work with. This project is in the very early stage of development.
