Last week(01/23/13), I had my first lab experience in my Science and Innovation class. We were given a task to build a robot which would be further controlled by a PC program allowing the robot to move in the student given directions. Me(Andrei Kozlov) and my colleague Marina Sidenko had been building it for an hour or so, but we managed to do this and the robot was working successfully! This class(01/30/13) we were given the task to measure the diameter, circumference, rotation, rotation 2. The results are:

Circumference is 0.157 which is computed by using the formula “Pie” * Diameter

a) Rotation is 558 and Rotation 2 is 554, wheel rotations is 1.55. One rotation is 360 and 1.55 is 558 or 554, according to the data which was obtained during the experiment.

b) The time was set for 1 second (1 second = 1000 milliseconds).

c) The distance the car moved is 0.25. Depending on how the car needs to travel, the turns can be obtained during the process.

We have used a ruler to measure the distance and came to conclusion that the distance = 30 cm(0.3m). This identifies the discrepancy between manual and automatic results which are 0.3 m and 0.25 m.

Then we have changed the Power in VI from “75” to “80” and the distance became 35 cm (0.35m). The automatic measurement is 28 cm (0.28m)

Being involved in this experimental precess was an interesting and unusual experience for me, I really enjoyed it!
