Warfighter Simulation


GruntSim is a Biomechanics and Physiology simulation tool for Burden Management that resulted from a five-year, $8.6 million project awarded to VSR by the U.S. Navy and called Enhanced Technologies for Optimization of Warfighter Load (ETOWL). The purpose of the recently completed GruntSim project is to create simulation tools for the study of load carriage by military personnel.

For example, military commanders using GruntSim can conduct trade-off analyses of load carriage in terms of agility, survivability, human performance, and physiological assessments by programming Santos with specific height and weight data for each person, loading Santos with gear selected from a menu of some 160 items, and having Santos perform various warfighting scenarios. Depending upon the stress experienced for each task, Santos’s spine, knees, ankles, and other joints will flash either green for low stress, yellow for moderate stress, or red for high stress (image courtesy of VSR project).


Santos™: The Virtual Soldier

Santos is a digital human modeling and simulation environment. Under development at VSR since 2003, and leveraging more than $23 million in research funding by the U.S. Department of Defense and industrial partners and collaborators, including Caterpillar, Inc., Ford Motor Company, Chrysler, General Motors, and others, Santos represents the state-of-the-art in technology application of physics-based and physiological response-based human modeling and simulation, with respect to task-based human performance assessment. Military vehicle evaluation, human systems integration, and human performance assessment are some examples of what Santos can do.




Squadron Scenario Training

Using the Santos scenario building and re-playing capabilities, this system of networked computers allows for visual training of squadron-level warfighters on various strategies.
