Transcript of Williamstown High School Sea Perch

Williamstown High School Sea Perch Competition By: Savanna Sampson and Michael Maddox Company Overview Poseiden's Helping Hand INC. Our Vision:
At Poseidon’s Helping Hand INC, we believe it’s our duty to help those in need of retrieving very intricate machinery, naval devices, government artillery, and any artifacts found in the vast bodies of water amongst the Earth.
We are not a company but rather a family. We share the rich data of the sea and look to discover more history as time passes on. If there is a recovery mission that is given to us, then we are on the job immediately surveying the area and using our robotic recovery devices (in which we call sea perches) to retrieve what ever we are assigned to repossess.
Our Team:
Mechanical Engineer: The engineer to whom of which works on the "mechanical" aspect of the project, or the physical construction of the motors and gears/locks on the sea perch.

Naval Engineer: This engineer that is responsible for the physical construction of the body of the sea perch and who studies how currents as well as the different surfaces implemented on the sea perch react to the water, currents, and particles in the water.

Electrical Engineer: The final engineer of our project, in which is responsible for the wiring of the motors, control box, and power supply to all come together and create a working pair of rear propulsion motors as well as a single elevation/depth control motor that all react to different controls (from the switches in the control/black box).

Our team is not very large and not small either. We are a team of cosistent workers and have about 10 members included.
Design and Manufacturing Process & Engineering Process Process Previous Knowledge and Research Design Priorities Tests/Experimentation Lessons Learned Charts/Drawings/Pictures Day 1:
Introduced to the topic/challenge
Began brainstorming and sharing of ideas
Developed the basic structure (body) of the sea perch
Day 2:
De-soldered the switches in which were given to us to reuse
Determined the polarity of the motors, wired them, and sealed the motors in canisters and wax to achieve a state of "waterproof" technology
Began electrical wiring of the motors to the switches, power supply, and ground
Finished the structure (body) of the sea perch entirely

Conducted at Niagara Falls located in Turnersville, NJ
4 forms of testing:
Video Camera
Object Pick up

Conducted at Retention Pond on the grounds of Williamstown High School
2 Forms of testing
Third Function( Thermometer)
Video Camera

With our design, we were more concerned with the maneuverability and simplicity of the sea perch. We figured that anybody could make an R.O.V. that is large, and bulky to perform a specific task, however we felt that with a smaller, more compact sea perch maneuverability would not be sacrificed as well as the overall value of the submersible. 3 primary test were conducted:
Submersion Test
Pool Test
Retention Pond Test
Among these tests were more intricate ones, however. Such as the Pool test included a recovery, maneuverability, speed, and video camera test. While the Retention Pond test included the second video camera test as well as our "3rd function" test (3rd function is a term or reference to our sea perch's other ability, movement, recovery, and temperature reading). Our research conducted was not so much about the nature of R.O.V.s and sea perches, but more so about soldering and wiring. This was our first time to be involved with the wiring of switches and motors in which we had not the slightest idea of how to tie 6 leads off the 3 selector switches to 2 prongs on a motor (positive and negative to whom of which determine direction as well as polarity). Therefore our process of research was mostly about electrical engineering and to those that have done this before, how they accomplished there's.
Our previous knowledge from I.E.D. and AutoCAD from our freshmen year, was not as applicable to the situation as we had hoped. However in that we learned the true design process, we did exemplify such very profoundly in the process in which we created the sea perch. Throughout the course of the project, we both have learned how valuable time makes itself through a project with deadlines much like that of this one. We also realized how well a team can manage, once a proper distribution of jobs have been divided amongst the team. Aside from the values of teamwork, we have also learned a tremendous amount of material than we previously knew about electrical engineering and wiring as well as water-type robotics. Recruiting At Poseidon's Helping Hand INC., we implement a form of rigorous screening before we accept new members to the team. We run a simple operation that is easily run with a team of associates that know eachother very well. Before any new member is recruited, they must first meet the following requirements:
Bachelor's degree in Sciene or higher
At least three years of experience in the field of engineering
Must be either an electrical, naval, or mechanical engineer
Anyother prerequisites are also examined to help us choose the best men and women for our team. Once they are accepted, they then are assigned an interview time and date. During the interview, their personality, ability to speak, and their understanding of engineering and engineering principles are all excruciatingly examined. Budget Information and Implementation No Sponsors, trade-offs, or additions (aside from the thermometer in which was previously purchased by a member of our team) to/for the sea perch. Use of computer technology
University of Drexel online
Education Resources Information Center (ERIC) Database Day 3:
Finished soldering, including the motors to the switches, to the black box (control box) and to the power supply as well as ground
Attached the motors to the body of the sea perch
Began the submersion test
Day 4:
Finish submersion test
Fix parts of the sea perch that were unsatisfactory to the general good of the sea perch
Prepare the sea perch for the official water test
Tape sharp points on the sea perch
Day 5:
Work out any of the final issues with the sea perch and finish the submersion test once more
