1. 14th Annual Greater Philadelphia SeaPerch Challenge & 2nd Annual Greater Philadelphia SeaGlide Competition
01 November 2018

2. 2019 GREATER PHILADELPHIA SEAGLIDE COMPETITION

3. 1 BUOYANCY GLIDERS & SEAGLIDE INTRODUCTION
MISSION TO MAP THE OCEAN AND BUILD FUTURE EXPLORERS

4. WHAT IS AN UNDERWATER BUOYANCY GLIDER?
Non-tethered, semi-autonomous robot
Has no propeller and uses very little energy to move
Utilizes a buoyancy engine for propulsion
A buoyancy engine changes buoyancy by taking in or expelling water
Changes in buoyancy cause the glider to rise and sink in the water while its wings generate lift, propelling the glider forward

5. SCARLET KNIGHT'S TRANS-ATLANTIC CHALLENGE
Rutgers University
Teledyne Webb Research
Apr 2009 – Dec 2009
221 Days km
11,000 Dive Cycles
Max 193 cm/sec (4.3 mph)
SPAIN NJ
Car could only travel 6.3 miles on the same amount of energy that Scarlet Knight used to cross the Atlantic.

6. BUOYANCY GLIDER MISSIONS
Gather data in the world’s vast and unexplored oceans
Sensors measure temperature, salinity, depth of the water, and more. 
Scientists can use this data to answer questions regarding:
Interaction of the ocean with the global climate system
Conditions affecting coral reefs
Fish stocks
Sea floor mapping
Military applications

IF WE BUILD IT,
THEY WILL COMPETE

12. GREATER PHILADELPHIA SEAGLIDE PROGRAM GOALS
Introduce the concept of autonomous underwater vehicles (AUVs)
Expand Science Technology Education Arts and Mathematics (STEAM) engagement and opportunities
Introduce microcontrollers and how to program them
Increase awareness of Naval Engineering through a fun and exciting program

13. 2019 SEAGLIDE PROGRAM Building & Coding Performance White Paper
Learn about underwater gliders and autonomous underwater vehicles (AUVs). Build a basic SeaGlide and learn about Arduino coding.
Performance
Compete in a multi-tiered performance competition.
Tier I | Glide across the pool
Tier II| Navigation Challenge
White Paper
Develop a white paper to describe how your design approaches and solves the performance challenge.
Commercial & Presentation
Create a minute marketing commercial that sells your concept and brand. 6-8 minute presenation to discuss your innovation. Directed Q&A session.

16. Competition Model | Tiered Approach
Each school must choose a tier level.
Each school must compete in the Performance, Presentation, and White Paper categories for that tier.
Performance Category Special Exception
Schools may compete in both levels.
Schools must submit one separate craft for each tier.

17. PERFORMANCE COMPETITION | TIER I

18. PERFORMANCE COMPETITION | Tier II Overview
Scenario:
The US has received intel regarding a nuclear warhead that was smuggled out of a politically unstable country and lost at sea when the ship carrying it sunk. The location of the warhead must be identified prior to the disarmament and recovery of the nuclear material. Unfortunately, it is located in a controversial location in the current world geopolitical climate. It is suspected that the warhead is lost somewhere in a large canyon system and may take weeks to locate. Deploying a submarine to the area would raise already high tensions in the area. This is a perfect mission for the SeaGlide.
Mission:
Identify the location of the nuclear warhead within the canyon.
Objective:
It is up to your company to design an autonomous or semi-autonomous underwater glider capable of navigating the trench and identifying the location of the nuclear warhead based on thermal measurements.

19. PERFORMANCE COMPETITION | TIER II
2019 Tier II Competition Performance Goals:
The Navy is looking for companies to build, test and demonstrate a craft capable of autonomously or semi-autonomously navigating an underwater canyon system.
Underwater gliders competing for the Navy contract will be evaluated on the following
Navigating a simulated canyon consisting of two turns
Finishing course at a target location
Speed

22. COMMERCIAL & PRESENTATION | COMMERCIAL
Produce a professional marketing commercial that focuses on:
Product differentiation, product features, product benefits, and pricing
Current and future design solution (how are you going to meet future requirements)
Encouraging the government to procure or fund the design and manufacture of your SeaGlide
Showing things that can’t be demonstrated in an oral presentation (motion, development process, teamwork)
Duration: minutes
The commercial will be followed by an oral presentation, but should stand on its own.
Helpful hint: This is a commercial for obtaining a government contract. Your priority should be to appear professional and knowledgeable. Being entertaining is valuable, but is secondary.

23. COMMERCIAL & PRESENTATION | ORAL PRESENTATION
Oral presentation with accompanying slide presentation
Provide more details than the commercial
Show things that can’t be demonstrated in a commercial (close-up photos, tables of data, lists of parts).
Discuss design process and obstacles you overcame.
Discuss alternative designs your team considered (i.e. Analysis of Alternatives), the pros and cons of each, and why you ultimately chose your final design.
Duration: 6-8 minutes
Helpful hint: Don’t read your tables and lists, but certainly discuss any interesting aspects. More graphs, less paragraphs.

24. COMMERCIAL & PRESENTATION | Q&A
This will follow the commercial and presentation.
Be prepared to address any of the following:
Clarifications regarding your commercial and/or presentation
How specific scientific principles apply to your design
How your design would handle a specific/new situation
How your design could be improved to handle a specific/new situation
Duration: 5 minutes
Helpful hint: Brainstorm theoretical questions with your team and practice answering them.

25. WHITE PAPER
Submit a White Paper that utilizes the performance scenario as the basis for the paper.
The White Paper shall contain:
An explanation of how your SeaGlide meets the mission requirements
An explanation of how specific scientific principles apply to your design
An analysis of alternative
Computer code, clearly commented and formatted
Further details and a format for the White Paper is forthcoming.
