Central to the notion of autonomy is delegation of control - an autonomous system is one which has control over some, if not all aspects of its behaviour. Traditionally, behaviour has been grounded in the physical world and the system in question has been a single self-contained entity. In short, think mobile robots. We have taken a different perspective, inspired by Koestler's concept of a holon [1]. According to Koestler, a holon is an identifiable part of a system that has a unique identity yet is made up of subordinate parts and in turn is part of a larger whole. Examples of such structure are common in biological systems (cells, organs, lifeforms), social organisations (soldier, section, platoon, company) and engineered systems (machine, cell, factory, enterprise). While the components in these systems (for example a pick and place robot or a manufacturing cell) exhibit autonomy, they must also be able to operate as part of a larger whole (manufacturing cell and factory, respectively). This requires the components to have the ability to work together to achieve these larger, team-oriented behaviours. Thus we view an autonomous system not as an individual entity, but rather as a team or network of entities that are able to work autonomously or cooperatively as the need arises. In Koestler's terminology, such a network is called a holarchy. As with traditional autonomous systems, such networks are situated within an external environment, that may be either virtual (as in computer games) or physical.
