Engineering Requirements

Client Requirements	Engineering Specifications	Justification
10	A 12-volt, deep-cycle marine battery will be used for power	A 12-volt marine battery is currently being used in the airboat
4	Retractable hose is accessible in the down position	The hose that draws water from the lake can also draw in a sanitizing solution at the truck
6	Temperatures between 45- and 95-degrees Fahrenheit are recorded	Full range temperature detection for Central Florida lakes and ponds
3	5 liters will be collected	Accounting for spillage when drawing sample water from the device
7	Travels approx. 1600 feet round-trip	The device must be able to sample and return to the shoreline
9	The Ardupilot autopilot control module will steer the boat	A dedicated autopilot system will be less strain on the sampling equipment
8	GPS coordinates are used to be within 10 feet of the established center of the lake	+/- 10 feet is more than acceptable for finding the sampling location
2	Final dimensions should fit within a 5 ft x 4 ft space	Cargo space is determined by subtracting the two coolers from the 6-foot truck bed. The device will be stored in the remaining space.
1	The device fits on a hand cart or has wheels and a handle	The operator will be able to remove the device from a truck bed and wheel it to the shoreline rather than carry it
5	The 3 gallons/minute pump will fill and flush the tank	Filling the tank completely will rinse all surfaces inside the plumbing and tank
