For the past two week of class we’ve spent some time creating robots out of leggos. This task was not easy at first. After all, I haven’t played with leggos in quite sometime. But after carefully reading the directions, and finding out which piece goes where, voila!..we had a robot!

These robot, once put together, were able to run on through manually selecting directions on the computer! We ran several tests for our robot. We figured out that the circumference of the wheels were .1727m. This helped us calculate the velocity. For a power of 75 we manually calculated that our robot moved .25 m. The computer said it moved 0.23034 m. So we weren’t too far off! Then we tried it at a power of 100. We calculated that the robot moved 0.39m. The calculator said it moved 0.358 meters. Lastly, we tried a power of 50. We calcutlated .17m, while the computer calculated .1535m. For each power we ran the robot three times, and got similar answers each time. Because our answers were a little off for each, I calculated the percent error for each power. For a power of 75, the percent error was 7.864%. For a power of 100, I got 8.205%. Lastly, for a power of 50, I got a 9.706% error.

Overall, this experiment was surprisingly fun. I’m definitly not into science so it was interesting to take a step away from a text book or lecture, and do something more engaging. I look forward to doing more handson activities in the future!
