During this lab my partner and I were required to measure the distance and velocity of our robot car.  At first we were confused with the whole concept, but soon realized it wasn’t as difficult as we thought it would be.  We picked three different power levels which were 75, 73, and 69.  We kept the powers closer together so our data wouldn’t be too spread out.  The distances the car traveled varied from 46 centimeters to 54 centimeters, which we measured with a ruler.  Ultimately we had to calculate the percent error with this equation,

%Error= (Measured Distance)- (Lab view distance) x100

½(Measured + labview Distance).

Our percent error varied from a 0% to 2% and lastly 9%.  We found that some causes of these errors might have been due to incorrect measuring, different starting points, as well as other factors.  From our percent error we realized that the higher the power, the more percent error there was.  We received a 0% error when we were on the power of 69.  Ultimately this lab helped me calculate multiple things like the velocity and distances traveled as well as the percent error.
