1. Survey And Recovery Autonomous Hovercraft

2. Overview - Capabilities Maintain a straight course (within some error) Scan a flat area for objects Avoid water FLOAT! (worst case)

3. Hovercraft Chassis Circular platform ½” blue insulation foam core (Tentative) fiberglass-layup outer body Diameter TBD

4. Lift System “Bag Skirt” hovercraft design Rule 12V 4” bilge blower 235 CFM max. May also be used for thrust (pending testing) http://www.amazon.com/Rule-240-Marine-Blower-4- Inch/dp/B000O8D0IC/ref=sr_1_1?ie=UTF8&qid=13279 87842&sr=8-1

5. Battery 11.1V 2200mAh 25C Li-Poly Battery Pack 25C = 55A continuous discharge rating Ample Power! http://www.amazon.com/11-1V-2200mAh-Li-Poly- Battery-Deans/dp/B0042GAWG0/ref=pd_sim__1

6. Metal Detector Building a (good) metal detector is complex Target size/weight achievable, but not in this time frame. Simulated “metal” detection using omnipolar hall effect sensors and magnets.

7. Water Awareness Tendrils Schmitt triggers
