In this experiment, we tested our robot at three different power levels. We started with 75 power then 50 and final 25 power and did three times for each level. The 75 power we gave the robot 1 second of power. The 50 and 25 power runs we gave the robot 2 seconds of power. With the data we recorded, then we calculated the velocity and the error percentage for each run. We used a ruler to measure the distance the robot has been travelled.

Even though we tried to reduce the error percentage, we still can not do as perfect as the computer does. The data we got for the error percentage is between 0%  to 7%. Error percentages come from the relationship between the Labview measurement and the physical measurement. We recorded when the program is recording. The closer these two measurements are, the lower the error percentage. These errors could have happened because of the ruler can be moved by the robot when its moved or the robot not traveling in a straight line,  which would shorten its distance on the ruler. The lego robot activity showed that little adjustments to variables can change the data entirely, which can increase the error percentage.
