- ABSTRACT:
- ~~~~~~~~
- AI planning research has historically operated in formal abstractions
- of the real world. This approach was useful in discovering many
- fundamental issues underlying planning; also, problems in simple
- domains such as the blocks world can turn out to be surprisingly
- difficult. Lately attention has turned to planning for more realistic
- domains in which micro-world simplifying assumptions do not hold.
- This shift of focus introduces a new problem of validation and
- comparison of different planning theories and systems. A proper
- domain for planning problems must be realistically complex but also
- simple enough to support controlled experimentation.
-
- To address these questions, we developed the ARS MAGNA robot
- simulator. The simulator provides an abstract world in which a
- planner controls a mobile robot. Mobile robotics is a particularly
- apposite domain since it is a major application area for AI planning
- techniques. ARS MAGNA's environment and robot models are based on
- current robotics research, so that the domain is reasonably realistic.
- At the same time, we abstracted away from many (though not all)
- real-world details of kinematics and motor control. Experiments may
- be controlled by varying global world parameters, such as perceptual
- noise, as well as building specific environments in order to exercise
- particular planner features. The world is also extensible to allow
- new experimental designs that were not thought of originally. The
- simulator also includes a simple graphical user-interface which uses
- the CLX interface to the X window system.
