Less than $400

5. 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)

6. 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

7. Possibilities
Submarine Vs. ROV
