GeoBot 1

Updated 7/16/06

 Here you will find the start page for our latest project, the GeoBot. This will be our first outdoor roaming autonomous machine, and is already outweighs any robot we have made in my lab yet. The goal of this project is to create a autonomous robot that can drive from a release point to a predetermined collecting area at a specified distance, then collect rock and soil samples and return them to the base. Although this seems a rather modest task, it will require a machine that can cope with very rough terrain, avoid large rocks and trees, and maintain a heading to put it as close as possible to the collecting area. Consequently the robot will be big and heavy, and will operate completely different from the ordinary indoor wall banging servo bot. Here are a few points we will address:

- 12vdc dual track heavy duty tank drive base - A single main processor running a complex Finite State Machine that is behaviorally based - All sensors will function in bright sunlight outdoors and will include bumper, sonar, scanning sonar, and Compass -Testing will be in a series of real world outdoor Arizona environments, with real dangers and obstacles. - Outputs to include piezeo speaker, serial LCD, and of course the motorized mechanical collection arm.
