We’ve been spending time with the robotics running different experiments to see how things work. For this experiment we used the VI to understand how straight rotation works to measure the distance the wheels travel, and the speed at which the car travels. We ran the VI and recorded the wheel rotation (in degrees and in number of turns), the time it took for the wheels to turn (in seconds and milliseconds), the distance the car moved and we measured the distance with a ruler and compared our results with that of the VI. We repeated this same procedure 5 times as you can see in the photo of the table. Then we talked about how the degrees that the wheel rotated related to the number of turns of the wheel, how seconds related to milliseconds, how the distance related to the number of turns and what could account for the discrepancies? It was interesting to see the discrepancies as we went along. For the majority of my data the lower the power was the higher the discrepancy became where as the higher the power the lower the discrepancy became. We found the percent difference by (druler-dlabview over druler+dlabveiw) multiplied by 100% to get the discrepancy. These experiments help you understand energy and sustainability issues by getting you to hands on work with something to see energy in use and figure out the math behind it. It was a fun, hands-on way to learn more about energy and sustainability issues.
