2 Experimentation We spent a lot of time in the lab experimenting with the light sensitivity to the sensors. 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 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. 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 Skis. We did changed from the front support design of The Nub to our final front support design of The Skis.

4 Final Design Large diameter wheels and tires Large diameter wheels and tires Front skis as supports Front skis as supports About two inches between the light sensors About two inches between the light sensors Dual tire carrier on back for traction 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. We made three different programs based on changing the light sensitivity of the light sensors. For black, blue and green we used 45% sensitivity. For black, blue and green we used 45% sensitivity. Red worked best with a 47% sensitivity Red worked best with a 47% sensitivity For yellow, we reversed the signs and set the sensitivity at 53%. 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. 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. 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).
