Technical ConstraintsName Description

Operating Depth

The ROV Must Operate at depths up to 3.2 meters

Operating Power

The ROV must operate from a 12.7V +/- 0.3V voltage source and draw less than 25 amps of current

Maneuverability The ROV must maneuver effectively enough to make it competitive

Video Capability

The ROV must have a minimum of one camera with a 3 meter range to

allow it to compete effectively

ManipulatorArm

The ROV must have a manipulator arm capable of lifting 2 Newtons

Operating Depth• Sank pressure canister to approximately 3.2

meters

Operating Power• MATE current limit is 25A• With all components in operation, total

current draw was less than 13A

Maneuverability

• Front and rear vertical motors work independently of one another

Maneuverability

• Horizontal motors work independently to allow for a tighter turning radius.

Video Capability• Camera 1 gives view of end of arm

1

3 meters

Video Capability• Camera 2 gives general view of space under ROV

Packaging - Housing• PVC Frame

– Light weight and customizable• PVC Pressure Canisters

– Waterproof end cap for easy repairs• Custom Paint Job

Packaging - Arm• Manipulator Arm

– Custom components– Higher manufacturing cost

Packaging – Motors• Motor Shrouds

– Maneuver faster – Safety

Packaging - Interface• USB Connected

– Compatibility • Easy Setup

– Open source camera software– Xbox Controller
