Both physics-based and semi empirical models can be coupled to provide realistic analysis. With its heterogeneous computing structure, Umbra allows physical devices to be integrated with simulations to examine how real systems might perform in complex virtual environments. Operators and physical robots can be connected to the Umbra environment for training.

Features of Umbra include:

• A design environment specific to robot system concepts analysis
• Analysis of both mobile and manipulator robot concepts
• Rapid tradeoff analysis and design concept evaluation
• A highly modular simulation environment that facilitates rapid model building
• A heterogeneous computing environment that allows model sharing
• The capacity to operate in NT and other systems
• Compatibility with standard synthetic aperture radar terrain maps and other environmental models
• Ability to analyze communication stability, novel mobility concepts, mobile manipulation concepts, multi-sensor integration, etc.
• Automated planning
