Mission Simulation Toolkit project is a flexible software system for autonomy research. The MST was developed as part of the Mission Simulation Facility (MSF) project, which was started in 2001 to facilitate the development of autonomous planetary robotic missions. Autonomy is a key enabling factor for robotic exploration. At present, there is a large gap between autonomy software (at the research level) and software that is ready for insertion into near-term space missions. The MST bridges this gap by providing a simulation framework and a suite of tools to support research and maturation of autonomy.

The requirements for a simulator that supports autonomy are significantly different than those of conventional robot simulators. First, since high-level autonomy software is intended to control a complete robotic system, a variety of models (terrain, kinematics, dynamics, sensors, power, electromechanical subsystems, etc.) are required. Second, in order to test autonomy software in a range of situations, it is necessary to provide controllable variability and failure injection into these models. Third, because autonomy software is generally developed on a wide variety of platforms and may target robotic systems that are still under development, mixed operating system support and flexible interfaces are needed.

The MST addresses this unique set of requirements through the use of a distributed framework based on the High Level Architecture (HLA) standard. A key feature of the MST framework is the ability to plug in new models to replace existing ones with the same services. This enables significant simulation flexibility, particularly the mixing and control of fidelity level. In addition, the MST provides automatic code generation from robot interfaces defined with the Unified Modeling Language (UML), methods for maintaining synchronization across distributed simulation systems, XML-based robot description, and an environment server. Finally, the MSF supports a number of third-party products including dynamic models and terrain databases.

Although the communication objects and some of the simulation components
that are provided with this tool kit are specifically designed for
terrestrial surface rovers, the MST can be applied to any other domain,
e.g. aerial, aquatic, or space. This tool kit contains a Communication
Object library that supports surface rover simulation and the following basic components:

· Simulation Controller (basic simulation setup and time management)
· Command Executive (for scripting a scenario)
· Locomotor (controls steering and locomotion of rover)
· Dynamics Engine (simulates rover/terrain interaction)
· Power Manager (manages battery resource)
· Rock Detector (a basic distance/range detector)
· Display (basic graphical 3-D display)
· Debugger/Command Logger (for testing and logging simulation events)
