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

2019 GREATER PHILADELPHIA SEAGLIDE COMPETITION

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

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

SCARLET KNIGHT'S TRANS-ATLANTIC CHALLENGE Rutgers University Teledyne Webb Research Apr 2009 – Dec 2009 221 Days 7409.6 km 11,000 Dive Cycles Max 193 cm/sec (4.3 mph) SPAIN NJ https://rucool.marine.rutgers.edu/atlantic/index.html Car could only travel 6.3 miles on the same amount of energy that Scarlet Knight used to cross the Atlantic.

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 Glider guts!

2 2019 GREATER PHILADELPHIA SEAGLIDE COMPETITION IF WE BUILD IT, THEY WILL COMPETE

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

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 1-1.5 minute marketing commercial that sells your concept and brand. 6-8 minute presenation to discuss your innovation. Directed Q&A session.

TEACHER & STUDENT TRAINING 2 Day Training at Temple University Date: November 16th and 17th Participation Limit: 2 Teachers and 2 Student 2 Day SeaGlide build Construct and test a glider 2 Day Arduino coding training Learn introductory to advanced coding

Competition Model | Tiered Approach Tier I Introductory Level Competition Compete with basic SeaGlide kit 3 Judged categories - 1st, 2nd and 3rd place receive certificates Overall winner receives trophy Implemented 2019 Competition $50 Max Budget Tier II Intermediate Level Competition Compete with single modification to SeaGlide kit 3 Judged categories - 1st, 2nd and 3rd place receive trophies Overall winner receives trophy Implemented 2018 Competition $100 Max Budget

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.

PERFORMANCE COMPETITION | TIER I Side View Objective 1: Glide across the width of the pool (50’) Objective 2: Navigate as straight a line as possible Score based on time and accuracy Top Down View

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.

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

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: 1-1.5 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.

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.

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.

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.
