  1. Preliminary Design ReviewWeek 7 THE DUKES OF HAZARD CAMILLE LEGAULT, NEIL KENNEDY, OMAR ROJAS, FERNANDO QUIJANO, AND JIMMY BUFFI February 28, 2008

  2. Previous Week Action Items • Work on Engineering Feasibility Studies • Using models and experiments • Using information from research

  3. Figures from Trade Studies

  4. Figures from Trade Studies

  5. Figures from Trade Studies

  6. Previous Week Ctd. • Initialize interfacing tasks • Write program to fully interact with RC car. • Develop a circuit board that will allow interfacing between microprocessor and RC vehicle.

  7. Logic of Program • Program designed to output three PWM signals using a single timer that interrupts at 0. • Main Program • Initialize output bits. • Turn on interrupts. • Clear interrupt flag. • Turn on counter. • Set signal low. • Set values for speed, wheel angle, and arm angle. • Assign longest value as c • Assign second as b. • Assign shortest as a. Interrupt when counter reaches 0. Were all outputs low? Set all outputs signals high and load counter with a. Was counter = -a? Drop shortest signal, load counter with –(b – a). Was counter = -(b – a)? Drop middle output signal, load counter with –(c – b). Drop longest signal, load counter with –(total – c).

  8. Next Weeks Action Items • SPRING BREAK!!!

  9. Next Week Ctd. • Ordering parts and materials • Based on result from trade studies • Test GPS system for accuracy • Comparing a known path to path generated by GPS
