During class, we built a robot using Lego’s. We used a program called labview to run tests on the robot. We measured the diameter of the wheel first, which came out to 5.5 cm. Once we figured that, we multiplied the 5.5 cm by 3.14 then divided by 100, which came to .1727 and that was the circumference of the wheel. We ran three tests all at different power. The first was at 75 and the time was for one second. The distance traveled was .58 cm with a number of rotations of 3. The second test was at a power of 50 for one second and the robot traveled a distance of 38.5 cm, with a number of rotations of 2. The third test had a power of 25 and the robot traveled .17 cm for one second. We compared the three tests to what the labview program shot out and with any experiment there will always be a margin of error.
In doing this experiment is was very interesting to put a robot together and figure out distance and velocity. It brought back some childhood memories while working with Lego’s. I have had some previous experience taking Physics during my Senior year of high school.
