For the previous two classes, we have worked together in pairs building and programming LEGO robots. Although difficult to assemble due to inexperience on my part with the pieces and confusion over the instructions, my partner and I were able to create our robot with minor defects (some of the pieces just wouldn’t fit). Once built, our robots were plugged in and synced with the computer programming software for the device. Although the steps were explained I still had trouble programming the correct sequence in order to make the robot follow different commands. On the first day we only attempted simple functions, which included moving for a short distance and stopping at a specific time. On the second day, however we were able to attempt much more. Withthe help of my partner, Jason, we were able to follow the instructions and make our robot move, stop, change directions, and make noise. We were able to program the robot and download the material so that it could complete loops and run continuously through the sequence we directed.

Following the directions of the lab we were asked to measure the distance our robot moved at different power levels. In order to do this we measured the diameter of the tire and multiplied that number by p. The diameter, 5.5 centimeters (0.055 meters), multiplied by p provided an estimated distance of 17 centimeters (0.17 meters). Once activated at the instructed power level our robot moved approximately 16 centimeters.

For our next instruction we were asked to make our robot drive in a circle with a one-meter radius. In order to do this we needed to adjust the tires to different power levels in which one was faster than the other. After one failed attempt (the radius was under one meter), we were able to complete the task. The next instruction of programming the robot to move in a one-meter radius circle while reversing direction was completed quickly due to the previous experience with our first circle. Adding a sound to play at the end as well as creating our own unique program was also done without much difficultly.

Overall working with the robots was a unique experience. I am typically not interested in labs like this, however it was interesting to put the robot together and think its relation to energy. Working with the robots was also a good way to become familiar with our class partners and to understand the team dynamic.
