Overview

The Control Agent Architectures Group (CAAR) performs research, development, and testing of software used to manage automated and autonomous operations for terrestrial, aeronautical, and space vehicles, and system processes and activities within these craft. The core of this automation software is centered on an executive that operates the system while monitoring the system state and responding to system state changes. There are two primary approaches to execution: one is to use procedural descriptions that specify what is to be done; the other is to use declarative descriptions that bound what can be done. CAAR is developing architectures that support both approaches, as well as interactions with human users.

Project List (Active)

Collaborative Decision Systems
Project Lead: Robert Brummett

Intelligent Deployable Execution Agents (IDEA)
Project Lead: David Rijsman
Development and refinement of an autonomous agent architecture. Project leads: David Rijsman and Paul Tompkins.

Spacecraft Autonomy for Vehicles and Habitats
Project Lead: Ari Jonsson

Universal Executive (PLEXIL)
Project Lead: Ari Jonsson
We are developing a language, called PLEXIL, that is designed specifically for flexible and reliable command execution. It is designed to be portable, lightweight, predictable, and verifiable, and at the same time it is very expressive. Project leads: Ari Jonsson and Vandi Verma

Project List (Inactive)

Apex
Project Lead:Peter A. Jarvis
Development of a versatile task-level control architecture for applications, currently including UAV (robot) control and engineering-oriented human simulation, in familiar but uncertain and time-pressured task environments.
