Umbra Utility v. 1.1

This is a utility library to support umbra core. These utilities are widely disparate in capability, but largely serve to extend the core Umbra. This is a catch-all library for useful modules such as positioning modules, logic and statistical distribution modules and other general purpose classes and modules.

Mobility - Version 1.0

This package contains, for the most part, the base classes and interfaces for vehicles and characters. Originally everything was in UGV, but things were split out to simplify the design since the assertion of UGV1.0. Modules in UGV, UWV, and UAV will inherit from classes in this package. There is also a high-level system that is a base class for systems in UGV, UWV, and UAV.

Sensors Umbra Package v 1.0

This package contains modules that model sensors in Umbra. There is a mix of modalities for both accumulating and tracking energy sensors: seismic, magnetic, and radiation. Some modules fuss information from multiple sensor types. Sensor devices (e.g., seismic sensors), detect objects such as people and vehicles that have sensor properties attached (e.g., seismic properties).
