abstract = "The term animat refers to a class of simulated
animals. This article is intended as a nontechnical
introduction to animat research. Animats can be robots
interacting with the real world or computer
simulations. In this article, the use of
computer-generated animats is emphasised. The
scientific use of animats has been pioneered by
artificial intelligence and artificial life
researchers. Behaviour-based artificial intelligence
uses animats capable of autonomous and adaptive
activity as conceptual tools in the design of usefully
intelligent systems. Artificial life proponents view
some human artifacts, including informational
structures that show adaptive behavior and
self-replication, as animats may do, as analogous to
biological organisms. Animat simulations may be used
for rapid and inexpensive evaluation of new livestock
environments or management techniques. The animat
approach is a powerful heuristic for understanding the
mechanisms that underlie behavior. The simple rules and
capabilities of animat models generate emergent and
sometimes unpredictable behavior. Adaptive variability
in animat behavior may be exploited using artificial
neural networks. These have computational properties
similar to natural neurons and are capable of learning.
Artificial neural networks can control behavior at all
levels of an animat's functional organization.
Improving the performance of animats often requires
genetic programming. Genetic algorithms are computer
programs that are capable of self-replication,
simulating biological reproduction. Animats may thus
evolve over generations. Selective forces may be
provided by a human overseer or be part of the
simulated environment. Animat techniques allow
researchers to culture behavior outside the organism
that usually produces it. This approach could
contribute new insights in theoretical ethology on
questions including the origins of social behavior and
cooperation, adaptation, and the emergent nature of
complex behavior. Animat studies applied to domestic
animals have been few so far, and have involved
simulations of space use by swine. I suggest other
applications, including modeling animal movement during
human handling and the effects of environmental
enrichment on the satisfaction of behavioral needs.
Appropriate use of animat models in a research program
could result in savings of time and numbers of animals
required. This approach may therefore come to be viewed
as both ethically and economically advantageous.",
