Pro 4 Features and Capabilities Updates
The Pro 4 has been extensively updated to include many enhanced features and extended capabilities.
Pro 4 User Interface
The Pro 4 includes a custom hand controller that is built using the same industrial controls found in the Pro 3
controller. This controller is delivered with a default configuration, but can be customized to accommodate any
user's preferences. Additionally, any COTS or custom controller that works with a PC can be used with the Pro 4,
including wearable and immersive devices such as gloves and head mounted display/controllers.
Video can be displayed on two monitors, the built-in monitor and the PC display. Alternately, the video can be
displayed on one screen while the other displays an accessory output such as a sonar or position tracking chart.
The Pro 4 video can be recorded digitally (on the included PC), or using standard analog devices (user
supplied), or both. Digital recording of still images and/or video is built into the control panel and can be executed
with the push of a button on the controller. Digital recording is in industry standard formats and ready for
non-linear editing, on-line sharing, or DVD authoring.
The included PC can be configured to run accessory applications such as sonars, position tracking systems,
VideoRay's radiation detector and other sensors.
Sensor feedback is provided onscreen and includes the camera tilt and focus positions, lights setting, and
information from other onboard sensors, including temperature, humidity, power and communications status.
Pro 4 Power and Thruster Technology
The Pro 4 power supply has been upgraded from 48 Volts DC to 75 V DC, but still maintains the same low
power consumption of the Pro 3 due to more efficient power circuitry. To support this increase safely, the Pro 4
incorporates a Line Insulation Monitor (LIM) protection circuit. Like a GFCI, the LIM detects minor changes that
indicate a fault and safely powers down the system if a fault is detected.
The voltage specifications at the accessory port have changed. The main bus is now 24 Volts DC, but it is
isolated from the tether ROV power circuit and better regulated so that it is less susceptible to voltage variations
under thruster load. The 12 Volt DC available on the accessory port is now capable of supporting loads up to 30
Watts instead of the 6 Watts available in the Pro 3.
The VideoRay Pro 4's now includes custom designed and highly efficient brushless thrusters that deliver
unparalleled performance and reliability. In order to provide the optimal blend of power and control, the VideoRay
Pro 4's thrusters incorporate the following features:
The horizontal thrusters, coupled with hydrodynamically optimized propellers and nozzles, produce the
highest thrust-to-vehicle weight and thrust-to-drag ratios in the industry. This combination ensures users
will have the power when they need it, along with the ability to pull long umbilicals and work in currents that
divers wouldn't dare attempt.
Direct drive horizontal thrusters improve efficiency and reliability over the Pro 3 GTO.
The thruster placement and counter rotation provide a zero turning radius and extremely agile
maneuverability as well as a stable platform for the camera and sensors.
Vertical thrust now incorporates a 65 mm three bladed propeller, and ducted channels under the float
block. The enhanced vertical thrust and pitch-controlled dive and surface modes expand on the raw power
of the new thruster motor and propeller to deliver significantly higher performance than the Pro 3.
Motor controllers are tuned for lightning-fast responsiveness. In conjunction with joystick sensitivity and
independently adjustable gain these features ensure precision handling and the dexterity to maneuver or
maintain position as needed.
