ROBOTS
Class Definition:
CROSS-REFERENCE ART COLLECTIONS
This collection provides for a reprogrammable, multifunction
manipulator designed to move devices through variable
programmed motions for the performance of changeable tasks on
a repetitive basis without human intervention and all
subcombinations thereof specialized for use with such
manipulator.
(1) Note. It should be noted that this is a cross-reference
collection of art only and not a true "Class" within the
meaning of that term as used in the U.S. Patent
Classification System although it is a search tool which is a
part of that system. This collection will not, therefore,
take for original placement any U.S. Patent.
(2) Note. A robot usually has an arm* (elongated appendage)
which normally has three degrees of freedom*.
(3) Note. A robot must be reprogrammable to perform a
variety of different tasks. Thus, a numerically controlled
machine tool which may have an arm, but is designed to
perform only a fixed set of tasks, is not a robot.
(4) Note. Subcombinations (e.g., programs, actuators,
joints, grippers, bearings, gears, etc.) have been included
in all instances where there was a disclosure basis (e.g.,
for use in an industrial robot, programmable manipulator,
etc.). Some subcombinations, of general utility (e.g.,
containing no specific statement of use with a robot in the
disclosure), are also included, where in the opinion of the
Classifiers, the subcombination is readily adaptable for use
in a robot. An attempt has been made to provide search notes
for pertinent subcombinations of more general utility.
(5) Note. This cross-reference art collection provides a
general locus for all information relating to robot machines
or subcombinations and elements peculiar thereto, regardless
of the type of work which is done by that machine. Based upon
past development of the system of patent classification, such
patents are to be found in many classes, their disposition
being dependent on a number of diverse considerations. The
most pertinent classifications for subject matter dealing
with robots have been screened; however, it should be noted
that this cross-reference collection represents the initial
attempt to collect this subject matter and therefore should
not be construed as being the exhaustive locus for robot
machines in its present form.
(6) Note. This drawings associated with the definitions are
merely used to illustrate the basic concept encompassed by
the definition of each subclass, and should not be construed
as limiting the scope of the subject matter covered by any
subclass. [figure]
