Harrison- Today was the practice day. At the pool the ROV had to maneuver through the obstacle course. It is a series of hoops that are vertical, horizontal, and diagonal. It was very challenging due to refraction. It was hard to tell where the ROV was in relation to the hoops. Some changes had to be made in order to make the ROV neutrally buoyant. The ROV was also hindered by the fact that when vertical propeller is used the positioning of the ROV is interrupted. The balance is off, so it is hard to steer. The ROV was not tested in the salvage challenge due to time constraints. That will be the hardest challenge in the real competition.
Jill- Today the team was able to practice using the control system of the ROV in the water. The team finished attaching the motors and cutting off parts of the pool noodles, and was able to keep the ROV neutrally buoyant. The team found trouble when attempting to maneuver the ROV, but in the end the ROV was successfully passed through each of the hoops and back.
Sky: Today we practiced our ROV in the water. I operated control panel and we managed to navigate the ROV through 5 sets of rings, each orientated in at different angles. After setting the ROV down we noticed that the ROV was tilting forward, so we cut off of some of the foam in order to let it drive smoothly.

AquaSquad 5-26-15
Today AquaSquad finished the build part of the ROV. Next class the ROV will be put underwater, and tested. The motors were attached the the control board was finished and connected to the ROV. The motors will have to be calibrated and the floats will have to be sized so that the ROV is neutrally buoyant. The zips ties were the most troubling part of today. 2 zip ties were ruined due to bad planning.
Jill- Today the team finished the control box, but ran into many challenges regarding this. The lid of the control box was put on upside down, an error that was fixed by Ms. S. Through this error, the team also found that one of the wires had been accidentally cut. The team had to cut the zip ties, and resolder the motors. In the end, the team was successful and managed to get all of the motors and the control box working.
Sky: Today we finished the design of the ROV however we noticed shortfalls regarding how the motor was zip-tied and the soldered wires. We worked extended time during tutorial and managed to overcome these shortfalls to recover our original design of the ROV. After testing the motors we discovered that the ROV was operational.

Today the team was able to complete the drilling of the holes in the PVC pipes. The team was also able to begin soldering the control box. There were a few challenges with soldering, but the team was able to work well together to overcome these challenges.
Sky: Harrison and I finished drilling holes into the PVC pipes. After finishing the drilling we made more modifications to the base of the design in order to increase stability and balance. We struggled with determining where the motors would be, but after some cooperation with our team we figured out some potential spots for the location of the motors. We marked those spots with a black sharpie to aid us in drilling the holes for the motors.

Jill: Today the team was able to solidify design ideas, as well as completing the propellers and beginning drilling the holes in the pipes. The team worked well together to complete different parts of ROV. We had some challenges with the Vise Clamp, but were able to overcome these challenges and create the holes in the piping.
Sky: Harrison and I reviewed the original ROV design and made modifications to it in order to balance the weight so that it would not capsize on one side during the testing. After modifying the design we continued to drill holes into the ROV in specified spots in order to attach the motors and for water to fall in.
Harrison: Sky and I review the designs for the ROV. Some changes were made to increase stability. Holes were drilled so that water could get inside the PVC pipe in order to keep the ROV under the water. The hardest part of today was drilling holes in PVC, The vice grip that was used was confusing, it turned out that I had been tightening it the entire time, instead of loosening it.

Jill: Today the team was able to fully tape, solder, and waterproof the motors, as well as cut the pipe and begin building the ROV. Some challenges were found when putting the wax on the motors, but they were resolved and all motors were successfully waterproofed. The team worked well together to complete separate tasks, even though one team member was absent.
Harrison: Absent today
Sky: Today I constructed the ROV from scratch and managed to cut and craft the base of the ROV. After crafting the ROV we then used the drills to begin drilling holes on the marked sections of the ROV. This allowed us to have an easier time the next work day so that we can continue off from where we left.

Today, the team was able to decide on a design idea. The decision was unanimous and easy to come to, which was a success. The team had some troubles deciding the length of the pipes that would be used, but in the end a decision was made. One team member was absent today, which made the process of deciding somewhat difficult, as there was hope that it would be a group decision. The team also ran into the issue of working with the obstacles, as they seem to be difficult to accomplish. All in all, the team worked through the errors and had many successes. The team will cut pipe next class
Sky
Make up work: I made up my work by cutting the pipes and then assembling the base of our ROV. Each pipe was cut to its represented length based off of the design plans. After cutting and assembling the ROV we noticed shortfalls on the design and we began to brainstorm possible adjustments we could make to improve the engineering of the ROV.

Today the team made our own designs for the ROV and selected a final design. The final design was based of one of the students designs, the dimensions were changed to make it smaller. The hoops the ROV had to fit through are very small, so the ROV needs to be small in order to make it easier to maneuver through them. AquaSquad think that smaller is better. The team will cut pipe next class.
