Day 1 05/04/16
We designated a leader and a blog leader, figured out the technology, filled out the "What Is An ROV?" sheet, and learned how to make daily logs.
Day 2 05/06/16
Today, we worked on the "What is an ROV" page as well as the "The Challenge" page. While we wrote most of the "What is an ROV" page on Day 1, making the page entailed of answering questions about what an ROV is, what parts an ROV has, how ROVs move, and what some examples of ROVs are. My job, in particular, was specializing on the different parts of an ROV. We also worked on the "The Challenge" page, which entailed of writing about the different tasks that our ROVs are meant do do, including the time limit for the tasks, the rational behind each task, and measurements involving the tasks. My job was to take information about the ROVs from schoology, write measurements down as they were told to me, and write the rational behind tasks #2 and #4. I learned how to better work as a team with my group mates, which is especially challenging in the absence of Lindsay, our blog leader. Next meeting, we will start working on the ROV base.
Day 3 05/10/16
Today, I watched videos on soldering technique and started to practice on a "Learn To Solder kit" This task entailed paying close attention to the details of the different parts of the solder as well as, afterward, where safety equipment and practice soldering on the kit itself. It was a challenge to absorb all the information, and I had to watch some of the videos more than once. However, I learned how to solder a small circuit board and how to set up the equipment and take it down after class. Next class, I will continue to learn to solder and help my team start to build the ROV.
Day 4 05/11/16
Absent due to AP testing
Day 5 05/12/16
Today, I finished practicing on a "Learn to Solder kit." This task entailed of actually melting the solder onto the board and being careful not to use to much solder. I also stripped a power wire and put on alligator clips. It was a challenge to do so much in so little time, and I ended up "biting" myself with the alligator clips a couple of time. I did learn how to strip a wire and improved my soldering ability. Next class, I will solder the control board.
Day 6 05/19/16
Today, we cleaned off our motors, which we came in to wire on our off-duty hours during standardize testing. This task entailed of actively making sure any waterproof wax which had been squeezed onto the outside of the canisters that contained the wax and the motors had been cleaned off thoroughly. We attached propellors to the motors, and then attached the motors to the main frame. It was a challenge to understand all of the little parts we had to use to build the propellors, attach them to the motors, and secure the motors. We tied the motors a few times before figuring out how to tie them really tight. I learned how to tightly tie a motor to a PVC frame. Next class, we will work on attaching the other parts of the ROV to the main frame as well as adjusting the floatation device to achieve neutral buoyancy.
Day 7 05/20/16
Today, we sealed off our wires using electrical tape and a special wax meant to keep wire out. This task entailed of using deft hands to be able to completely seal off the space between wires. We also tied the wire to the control board tight to the frame. We had to be similarly dexterous to accomplish this as well as have a knowledge of how to tie tight knots. Next, we took our ROV to the pool and adjusted our flotation devices to achieve neutral buoyancy. To do this, we used a box-cutter to shorten our flotation devices, and we had to be patient to test out multiple lengths. Finally, we started to buy from the class emporium. Every team starts out with nine Mrs.S-dollars, and we spent one on a clothes-hanger we think will be useful to the challenges. It is difficult to figure out how to spend your pseudo-money in the most efficient way. I learned how to better water-proof wires, and I learned how to tie a wire to a frame in a more efficient way. Next class, we will work on farther improving our ROV with items from the emporium.
Day 8 5/24/16
Today, we better strategized how to make the best use of our Mrs. S dollars. It took careful experimentation and an analytical mind to determine that it was the best solution to cut the hooks from two clothes-hangers, as would be most optimal for picking up the "octopus" in the challenge by its "arms." We carefully placed the hooks and tied them to the frame. This involved being smart about where we put the hooks (we measured the diameter of the octo's "body") as well as good dexterity in cutting as well as taping and zip-tying the clothes-hangers down. Because we bought another clothes-hanger, we are down to seven Mrs. S dollars. We learned how to think critically and outside the box, and we learned how to make better use out of our resources. Next class, we will go to the pool and start testing our ROV.
