Project Objectives
High Priority Objectives
Unit can control to target depth in under 30 seconds under its own power
Unit can emergency surface (.i.e.- Break out from a deployment if too much time elapses, or the unit goes too deep)
Unit can hold a target depth±30 cm for a specified time window of at least 1 hour (through changing conditions)
Unit noise low enough to allow accurate hydrophone signal reception
Second Priority Objectives
Be able to fully extend a radio antenna above the surface of the water
Unit is no larger than 3 Liters
Keep unit cost low
Other Constraints and Issues
Battery life of 72 hours
Housing is water tight for up to 30 meters under water
WOW Design Solution
Unit can control to target depth in under 15 seconds under its own power
Unit can hold a target depth±10 cm for a specified time window of at least 1 hour (through changing conditions)
Prototype can switch between target depths in one deployment
Battery life of 168 hours
Housing is water tight for up to 100 meters under water
Unit can travel horizontally under its own power
Unit can send data remotely using bluetooth
Risk Reduction Strategy
Model thrust needed to dive/continue diving for a neutral to slightly negatively buoyant system
Calculate and model change in volume versus change in depth requirements for up to around 100m
