In the robot car experiment, we are using the VI system to understand how to measure the distance the wheels travels and what the speed of the car is. First we’ll have to measure the circumference of the wheel and then compute it into diameter, which in other word, “P*Diameter”. After measuring it, we’ll have to record the distance the car has went. Knowing the distance, we’ll put the distance in the VI system to find the number of wheel turns and the rotation in degrees. Also, we will need to calculate how much error it made. To find the error, we’ll have to subtract the distance of ruler from distance to computer (distance of ruler – distance of computer). In total, we had ran 3 tests, and all the results came out differently as we adjust the numbers on every try. Below is the results that came out.
1. 25cm/1sec 75 power 0.269m (computer) 0.25m (human) 0.529/2=0.259 (Average) 7.33%(error)
2. 16.5cm/1sec 50 power 1.65m (computer) 1.56m (human) 0% (error)
3. 50 power (2 secs) 33.1cm (computer) 33.5cm (human) 66.6/2=33.3 (Average) 1.2% (error)
