In the book "How to design and build your own custom robot" by David L.
Heiserman, Tab Books, I found a classification of robots according to their
"intelligence" (pages from 11 to 17). I wonder if this is just the author's
thought or if there's a sort general consensus on this theme. I personally
find this categories meaningful and useful.
I try to summarise some of the ideas:
PARABOT – it's a machine that can behave a fashion similar to that of a robot,
but is not a robot in the truest sense, because it lacks an element of
autonomy or self-determination. Heiserman puts in this class all the machines
that are directly or indirectly controlled by a human operator. Most of the
"industrial robots" fall here: they can perform complex tasks but need human
intervention at some point to switch from a task to another.
ROBOT – If a machine is something more then a parabot, it's a robot by
default. Key words are "autonomy" and "adaptability".
Alpha-Class Intelligence – A machine that has absolutely no capacity for
remembering past experiences; it exists only in a very narrow time frame of
the moment.
Beta-Class Intelligence – A machine with the ability to remember responses
from past encounters with the environment, and then call up those responses
when similar conditions arise later. A Beta-Class machine actually works on an
Alpha-Class level through the early part of its life, but as its hierarchy of
experience grows, it exhibit smaller amounts of purely random behaviour in
favour of "habits" it has learned.
Gamma-Class Intelligence – A machine that starts its life as an Alpha and soon
begins exhibiting the memory-related programming of a Beta. Then, as the
hierarchy of remembered responses grows and becomes refined with further
experience, begins generalising that knowledge to situations not yet
encountered on a first-hand basis.
There aren't examples of Gamma-Class robots in the book, but the author writes
he has published programs for engendering that sort of behaviour in the books
"How to build your own self-programmed robot" and "Robot intelligence…with
experiments".
