My partner and I put together the lego car called the VI that is programmed through LabView. We got to play around with the car and program it to do the motions we commanded it to. It was a really cool lab! We measured the distance the wheels traveled, the speed at which the car traveled, the diameter of the wheel, the number of wheel turns, and the percent error. We ran the VI 3 times and recorded the data. The rotation of the wheel was off slightly from one to the other. Most of the information was given by the LabView program, except for the distance moved which we measured ourselves and also the percent error.
the velocity of our run- the velocity of original lab run÷ velocity of original lab run x 100%= % error
