5/19/17 For class today, I listened to the Buoyancy Calculations lecture with Ms. S. After Gianna and Ana finished waterproofing their motors, I attached the camera and motors to the ROV itself and then went out with Ms. S to get the wet weight. We needed to do that in order to know how much pool noodles we needed to buy in order for our ROV to be neutrally buoyant. I figured out that I needed about 24 inches of pool noodles in order for the vehicle to stay neutral. Next class I will get the pool noodles and measure/cut/adjust it.
5/17/17- Today, I drilled holes in the frame so that water can go through it and the frame wouldn't completely float. I connected all the PVC's together, and then proceeded to take it outside and put pool floaties on the frame. It was difficult because I had to try putting the floaties in different locations to make sure that it floated up-right. Eventually, it worked but I did not have enough time to test it out with the motors. Next class, I will connect the frame to the motors and hopefully it will maneuver just fine.Date Absent: 5/15/17
Makeup Date: 5/16/17
During the makeup session, I met up with Gianna and Ana. They did their own thing with soldering, and while they were doing that, I decided to finish cutting up the PVC pipes. I finished marking down all the measurements and making sure that the pieces all fit together. Next class period, I will try testing out the frame with the sample motors.
5/12/17- Today, I immediately started re-building the official frame. Once I finished, I went back to my sketch and confirmed my final measurements. I went over it with Mrs. Schworetzky, and then got a "shopping cart sheet" to put in the quantity I needed for each material (elbows, PVC, T's, etc...) I also got all of the official materials today. Next class, I will work on measuring and cutting the PVC pipes.
5/10/17- For class today, I started off re-building the frame that I had created the other day. I adjusted some things and had an updated frame. For now, that is our final frame and so I decided to do our sketch with our official measurements for the PVC pipes. That was what I spent most of my class period doing besides cleaning up and sorting our bag. For our next class, I will start by re-building the "official frame" and showing my group to get their approval.
5/8/17- Today, I first sat with my group and we decided to distribute main roles for the project. I assigned myself to be in charge of building and assembling the frame. After we decided as a group, I watched some training videos and read some guidelines. When I was ready, I played with some old PVC pipes and started building ideas for our prototype. I still do not have an exact vision for our ROV, but I got a better understanding of how to assemble the frame and what kind of structure I wanted to create. Next class, I will continue working on the frame and hopefully having a final product to draw out.
5/5/17- My main job for today was to update the blog to make sure each person had their own page/tab for Daily Logs. I also studied for about 10 minutes to make sure I knew exactly what an ROV is before getting interviewed by Ms. S. After we passed, we decided to go to the kiddy pool to test out the older ROV's. I myself got to use the controller switches to maneuver the ROV. My plan for next class is to keep updating the blog and to start planning the design and structure of our ROV.
