Problem Statement As High School students, we have not fully investigated or implemented the concepts and applications of electronics, fluid dynamics, energy systems, mechanical systems, and calculus in the construction and use of submersible technologies

Research Ballast Systems Hull Design Propulsion Systems Electronic Control Servo Power Source Components

Project Scope Research, design and build submersible Deliverables: Submarine Final Report Final PowerPoint Presentation Consult Experts: Teachers Hobby Experts Hardware Experts Less than $400

Criteria Must function underwater Waterproof Electronic components are protected (safety) Movement with 3 degrees of Freedom Ballast System Maintain Neutral Buoyancy [still and motion] Diving range 5-10 ft. (optional) Video Feed (optional) Lighting (optional)

Constraints Limited weight due to buoyancy Limited Budgets ($400) Materials must withstand underwater pressure All materials must run off the same power source with the voltage drop Depth is limited to tether line
