GRI VROV Simulator

The VROV Simulator was designed and developed by GRI as an instructional tool to be incorporated into existing and planned ROV Pilot training programs. VROV enhances an instructor's ability to train and evaluate trainees in several ways:

Provide a new trainee with plenty of "Stick-Time" without hazarding personnel and ROV equipment
Extended manipulator support
User-defined fault scripting to develop a pilot's crisis handling abilities
Highly interactive objects, including CAT tools, etc. to train in equipment operation
Support for a wide range of ROV tooling, including skids, torque tools, soft-line cutters, etc. to train the pilot in tooling operation.
Support for a wide range of ROVs allowing the pilot to get used to the handling characteristics of each ROV.

VROV applies the technologies of Virtual Reality (VR) and dynamic physical modeling to generate realistic, scenario-based ROV simulations. It includes support for all standard components - acoustic imaging, obstacle avoidance, tracking units, underwater cameras and lights, manipulator arms – as well as ocean currents, variable, turbidity, sea-state, and tether effects.

System Configuration
The VROV system is a highly modular system that allows the customer to choose the components that would suit his or her application. The basic components required for minimal operation would be the ICC and VDM software modules. The following lists all the available modules for the VROV Simulator:

ICC (Instructor’s Control Console)
VDM (Virtual Dynamics Machine)
VCam (Virtual Camera)
VSonar (Virtual Sonar)
CIC (Console Interface Computer)
Tritech Sonar Interface Module

General Features:
Real-time dynamic simulation of ROV motion
Real-time simulation of tethered and un-tethered ROV and AUV hardware
High-quality, low-overhead rendering package
Accurate collision response
Supports Standard ROV sensor packages:
- Imaging sonar simulator
- Side scan sonar simulator
- Multiple Switchable Pan/Tilt/Zoom camera systems
- Adjustable flood and spot lighting
ROV tooling / manipulator support
Vehicle performance data logging and replay
Environmental effects:
- subsea currents, water turbidity, seafloor silt effects, sea state
Scenario-based simulation exercises
Synthetic or mapped undersea terrain using bathymetric data import
Tether modeling with Tether Management System , Cage with winch control or free swimming control
Support for a range of manipulator hardware controller such as the Schilling Master Controller with support for the Orion, Conan, Titan3 and Titan4 manipulators

The VROV Simulator is available in several different configurations, listed below:
Console Simulators

The VROV Simulator offers full console integration for OEM or replica ROV control consoles and sensor systems.

Desktop Simulators

The VROV Desktop Simulator has multiple configuration options. It can be used on a single laptop computer or multiple computers with additional displays. Control schemes are also customizable depending on scenario and customer requirements.

Manipulator Trainer:

The VROV Manipulator Trainer is able to accommodate virtually any manipulator, including integration into master-slave controller consoles, with support for positional and rate controlled joints. Operators can train on a wide range of existing hand-held tools or test new tooling designs.
