Artificial intelligence (AI)
is the science of making machines imitate human thinking and
behavior. There is not yet any AI system that can truly replace human
thinking, reasoning, and creativity. However, each AI system
mimics some specific aspect of human activity and/or
thinking. Artificial intelligence in the form of robots is used in
industry and search and rescue operations to take over physical
tasks. Artificial intelligence systems in the form of expert
systems, genetic algorithms, neural networks, fuzzy logic, and
intelligent agents are used to help humans find solutions to
"thinking" problems. Thinking problems include such situations
as decisions about giving loans to bank customers, sifting
through job applications to find the right person,
investigating drug interactions, and so on. Here are two examples of artificial intelligence systems
that are in use today. Robot "Babies" that Work in Difficult Terrain Guided by software, "marsupial" robots crawled through the
World Trade Center rubble searching for victims. These baby
robots along with the mother robot were developed by the
University of South Florida. The mother robot carried the
smaller robots in a pouch-like container to where they were
needed and then released them to search in spaces that were too
small for the larger robot. The small robots were tethered to
the mother robot so that they wouldn't get lost. (For more
informtion on these robot families, see Higgins, Amy."Robot
"Babies" Crawl through WTC Debris," Machine Design,

Bennigan's, Target, Blockbuster, or Universal Studios,
your application will probably be "read" first by AI
software. First, you'll be asked to answer lots of true/false
questions like T or F "I can argue hard but still keep it friendly" T or F "I hate to give up on solving a hard problem" T or F "I sometimes get a kick out of arguing" T or F "I like a job that's quiet and
predictable" The system's questions are based on the philosophy that
there is no such thing as a good or bad employee -- just a
good or bad fit. The questions and the analysis are designed to
find the people who would be good at a particular job. When this system was installed at Macy's, one of the
company's vice presidents took the test and was told that
there were no positions available for him. He was outraged and
wanted the system removed until it was pointed out to him that
with his experience, salary, and position in life, he would be
bored and frustrated in the job he was applying for. (Overholt,
