The term "artificial
intelligence" is defined as systems that combine sophisticated
hardware and software with elaborate databases and knowledge-based
processing models to demonstrate characteristics of effective human
decision making. The criteria for artificial systems include the
following: 1) functional: the system must be capable of performing the
function for which it has been designed; 2) able to manufacture: the
system must be capable of being manufactured by existing manufacturing
processes; 3) designable: the design of the system must be imaginable
by designers working in their cultural context; and 4) marketable: the
system must be perceived to serve some purpose well enough, when
compared to competing approaches, to warrant its design and
manufacture.
Robotics is one
field within artificial intelligence. It involves mechanical, usually
computer-controlled, devices to perform tasks that require extreme
precision or tedious or hazardous work by people. Traditional Robotics
uses Artificial Intelligence planning techniques to program robot
behaviors and works toward robots as technical devices that have to be
developed and controlled by a human engineer. The Autonomous Robotics
approach suggests that robots could develop and control themselves
autonomously. These robots are able to adapt to both uncertain and
incomplete information in constantly changing environments. This is
possible by imitating the learning process of a single natural
organism or through Evolutionary Robotics, which is to apply selective
reproduction on populations of robots. It lets a simulated evolution
process develop adaptive robots.
The artificial intelligence concept of the "expert system" is
highly developed. This describes robot programmers ability to
anticipate situations and provide the robot with a set of "if-then"
rules. For example, if encountering a stairwell, stop and retreat. The
more sophisticated concept is to
give the robot the ability to "learn" from experience. A neural
network brain equipped onto a robot will allow the robot to sample its
world at random. Basically, the robot would be given some life-style
goals, and, as it experimented, the actions resulting in success would
be reinforced in the brain. This results in the robot devising its own
rules. This is appealing to researchers and the community as it
parallels human learning in lots of ways.
Artificial
intelligence dramatically reduces or eliminates the risk to humans in
many applications. Powerful artificial intelligence software helps to
fully develop the high-precision machine capabilities of robots, often
freeing them from direct human control and vastly improving their
productivity. When a robot interacts with a richly populated and
variable world, it uses it senses to gather data and then compare the
sensate inputs with expectations that are imbedded in its world model.
Therefore the effectiveness of the robot is limited by the accuracy to
which its programming models the real world. |
