  2. Experimentation • We spent a lot of time in the lab experimenting with the light sensitivity to the sensors. • We started with a low sensitivity and work our way up to a good sensitivity. • We tinkered with the width between the light sensors and found that very close sensors were able to make tighter turns and wider spacing made for faster times in the straight-aways.

  3. Design Changes • Our initial design for the car is very much the same as our test car. • We did changed from the front support design of “ The Nub ” to our final front support design of “ The Ski’s.”

  4. Final Design • Large diameter wheels and tires • Front ski’s as supports • About two inches between the light sensors • Dual tire carrier on back for traction

  5. Light Sensitivity • We made three different programs based on changing the light sensitivity of the light sensors. • For black, blue and green we used 45% sensitivity. • Red worked best with a 47% sensitivity • For yellow, we reversed the signs and set the sensitivity at 53%.

  7. Design Problems • We had to little traction to the back wheels so we decided to add a dual spare-tire carrier to had weight to the rear wheels.

  8. Conclusions • Our robot attained third place in the robot showdown. • Looking at the results we realized that it would have performed better in small angle turns if we had reversed one motor (depending on the side of the turn).
