Introduction

The goal of this project is to create a system to aid a vehicle in autonomous

navigation using a Beagleboard-XM. The Beagleboard-XM embedded system is a

powerful, highly optimized and versatile device with an Advanced Reduced instruction

set computer (RISC) Machine (ARM) processor and a Texas Instruments TMS320

digital signal processor (DSP). With the use of digital signal processing techniques and

embedded technology; a leaner and more current system of navigation will be created.

Results

Environment : The vehicle inhabits the obstacle filled environment.

Ultrasonic Transducer/Sensor Array : Mounted in an array; the transducers are

excitation used to sent excitation to the world and interpret the returning signals into a

digital format.

Embedded Buffer : The embedded buffer will store all data received by the ultrasonic

receiver arrays and will be shared by both processors on the Beagleboard-XM.

Pioneer 3 : The platform that will house all other components. The wheels and mounting

point for the sensor arrays.

Beagleboard-XM : Embedded system that contains both the ARM and DSP processor

and controls peripherals.

Remote User : The remote user can receive diagnostic, position and situational

information via a wireless connection. Additionally, the wireless communication can be

used to take manual control of the vehicle.
