Overview n n n System Concept and Components Background and Market Research System Descriptions ¡ ¡ ¡ n n Control Radio Frequency (RF) Direction Finding Communications and Graphical User Interface Cost and Schedule Project Future

System Components n Extremely mobile user interface ¡ ¡ n Radio Frequency Beacon ¡ n Personal digital assistant Nintendo Game Boy Mobile RF signal generator Small autonomous car ¡ Modified remote controlled car with a microcontroller unit and sensors

System Concept n n n A mobile controller transmits drive parameters to vehicle The mobile controller receives sensed data from vehicle Two modes of vehicle operation ¡ ¡ Vehicle can track a RF beacon Vehicle can follow waypoints

Mode Concepts and Reasons n Track ¡ ¡ n Will locate and follow a RF beacon To show all of our skills Point to Point ¡ ¡ For vehicle testing Allows for future scalability

Market Research n n Competing Technology Remote car and sensor platforms being researched from MIT to high school students Most projects do not provide tracking/sensing technology that is integrable or upgradeable with current market technology Computer controlled sensor platforms. → ← Computer controlled racing, based on pre -programmable behavior.

Market Research Largest Markets n Safety ¡ n Scientific Research ¡ n “after an accident, the violations that frequently top the list are failures to keep pathways clear, floors clean, and emergency exits freely accessible” Jan Schut, www. plasticstechnology. com The Hawaiian Volcano Observatory (H. V. O. ) is a good example of an organization that regularly monitors and studies volcanic activity Entertainment ¡ Sam’s Club is selling twenty-four different types of RC monster trucks this holiday season…Smart Track is the natural integration of technology that Sharper Image and Radio Shack customers already use and are willing to buy

System Overview n n RF beacon Vehicle ¡ ¡ ¡ n RF receiver Vehicle controls Wireless comm. Base station ¡ Graphical user interface (GUI)

RF Direction Finding n Horn antenna gain pattern consists of a single beam with minimal sidelobes Horn 1 RF Beacon n Allows for a very simple RF direction finding algorithm ¡ ¡ Horn 2 Measure received power from both antennas Turn in direction of antenna with greater received power

Vehicle Speed Control Speed Demand n Determined based on the distance to the beacon Motor Speed n n Controlled by switching the motor supply “on” and “off” very quickly Responds only to the average effect ¡ Longer “on” – speed increase ¡ Longer “off” – speed decrease

Vehicle Direction Control Turn Demand n Determined based on position with respect to the beacon Turning Control n n Two servo motors on the front wheels control the direction Pulse width modulation (PWM) determines the angle of rotation of the motor ¡ Longer pulse – motor turns more ¡ Shorter pulse – motor turns less

Vehicle Microcontroller Unit n ATmega 32 MCU ¡ I/O n ¡ Operating voltage n ¡ 4. 5 V ~ 5. 5 V Speed grades n ¡ 32 programmable I/O lines 0 -16 MHz Power consumption at 1 MHz, 3 V, 25ºC n n n Active mode: 1. 1 m. A Idle mode: 0. 35 m. A Power-down mode: <1μA

Choice of Communication n Bluetooth: powerful but expensive, complex, and power-hungry Zigbee: developed for industrial applications… not present in consumer devices Wireless fidelity (Wi. Fi): integrated into PDA’s Game Boy, and many handheld platforms

Extremely Mobile User Interface n n n Has a very short setup time Easy to pack away Familiar technology to consumers Able to operate while client is in motion Possible languages and operating systems being considered are (Visual) C++, Palm. OS, Java/Flash

Extremely Mobile User Interface
