Description of Hormonal Activation for Subsumption

`Hormonal' Activation strategy for Subsumption Agents

By designing robots with a number of behaviors, the subsumption architecture must support the ability to decide which behaviors are appropriate at a given time and, from these, which one should be selected. Brooks [1991] describes a system of activation which is modeled upon animal hormone systems.

In this system, some of the augmented finite state machines of the basic subsumption architecture layers can halted or inhibited by the presence or absence of a hormone. This computational mechanism is designed to modulate the agent's behavior by thresholding the layers of AFSMs and preventing the activity of those levels below the threshold.

The hormonal mechanism leads to integration of many of the behaviors described for the subsumption architecture.
