Summary:
For the past two weeks, we have been using a program called LabView on the computer. With this program, we are able to manually decide on how the Lego robot will move. We can program the robot to move in different powers, distances, and numbers of rotations.

Objective:
The objective of the lab this week was to compare the distance traveled using the LabView program and a ruler.

Comment: From the experiment, I learned that the program is capable of measuring extremely accurate numbers. I was very impressed by this program and as a future reference, I would like to use this program again.
Questions & Answers:
1. The wheel rotation (in degree and in number of turns). How are the degree that the wheel rotated related to the number of turns of the wheel?
A: It is proportional. Every 1 rotation is 360 degrees.
2. The time it took for the wheels to turn (in seconds and milliseconds). How are seconds related to milliseconds?
A: In every 1 second, there are 1000 milliseconds.
3. The distance the car moved. How is the distance related to the numbers of turns?
A: From our previous calculations, the circumference is the distance that the car moved per rotation. Which is 0.1728m.
