Here are the few specimen entries for the Android Makers
Encyclopedia "T" topics:
t An anthropometric point of the face used by Farkas to describe
the geometry. This is another point near the ear?
These pair of points establish the skull-base width which is
a component of major cephalic ratios. The coordinates of these
two points are, since the exact functions may not be determined
as of :
[fnX(t(R)), fnY(t(R)), fnZ(t(R))] and
[fnX(t(L)), fnY(t(L)), fnZ(t(L))]
WHERE:
fnY(t(R)) and fnY(t(L)) are functions using the desired body
overall height ( mm ) as one factor. Some of the other
facial height ratios and measurements are expected to be
terms or factors within the final function yet to be
determined as of
An interim function:
fnY(t(R)) = mm - .547 * v_gn = fnY(t(L)). The constant .547
is from an expression buried in Model3.WQ1 which represented
54.&%. This constant must be replaced with a functional
variable. Of course, inequality between the right and left
side could simulate human asymmetry.
fnZ(t(R)) and fnZ(t(L)) are functions using certain factors,
among them being head depth calculations, measurements, or
other determinations. The exact expression is undetermined
as of
fnX(t(R)) and fnX(t(L)) are the functions left and right spacings
of the face expressed in a plus (+) and minus (-) dimensions
for the respective side of the face. This is about ½ of the
measurement or determination for the skull-base width. Of
course, inequality between the absolute values of the right
and left side could simulate human assymetry.
TEETH
The teeth are addressed as an intermediary item instead of
as an external as a matter of decision. False teeth could be
treated as an external, like spectacles, because they would then
be "detachable." However, it is normal for teeth to be permanent
and a human's remaining teeth survive with the remainder of the
skeleton.
It is because of their permanence (natural remaining) and
yet their transitory (false teeth) nature that the matter of
teeth is incorporated at an intermediary process level. Natural
or false teeth could be identified as a shred, but that schema as
of February 25, 1994 is unresolved.
Natural teeth should be shaped and fitted as early as possible because of their nature. However, if your android is ancient in appearance, you may want to consider false teeth and
then it would be a final, almost just prior to getting dressed,
step before you would likely put your android's teeth in.
Generally, android makers want an android with "natural"
teeth, or as naturally functioning as possible. By fabricating
and permanently installing your android's teeth by or in this
phase, that part is accomplished. Also consider; teeth are a
part of the support for the shape of the lips whether they be
full or thin.
If false teeth or training aid teeth (as supplied by medical
training firms like the Anatomical Chart Company, Skokie, IL) are
not satisfactory or available, then another method must be used.
One method would be to implant teeth in the respective bones like
they are in humans. That determination must be made early in the
design and engineering phase because it would be too late in the
intermediary layer processes to be meaningful.
The applicable method is to make a prosthesis very much like
false teeth. Painted ceramic teeth in a plastic gum could be
fairly easy to make by hand. Observe dentists and doll crafters
for methods and techniques that are helpful in this endeavor.
Another source of android teeth could be the novelty store.
The "clacker" mechanism could be removed and then the uppers and
lowers could be trimmed to fit the jaw and the maxillary for a
low-budget set of teeth. Although these teeth could appear to be unnaturally white and the gum lines likewise unnaturally red,
there still would not be much displayed for all poses other than
a "toothy" grin. Some "aging" could be applied if these are too
unnatural.
If some of the other limitations has been incorporated
within your android, then this should be commensurate with the
fabrication and quite satisfactory. After all, almost everyone
must work on a fixed budget. If your financial resources have
not imposed any constraints and you have not opted for any of the
previous (and successive) cost reduction options, then the thousands of dollars for professional dentist-made uppers and lowers,
or implants, may be the proper method.
The Tibia Length topic is from the encyclopedia source file. You

Tibialis anterior [Alexander, p.48, 53] is a muscle and as its
name indicates, is in front of the tibia. The lower end
connects to the foot bones close in at the front of the
ankle. When this pulls, the toes point up. I have not been
able to map this nomenclature to Gray's Anatomy. The best
candidate is the Tibialis anticus, but its site seems too
wrong.
tr An anthropometric point of the face used by Farkas to describe the geometry. This is the a centerline point at the
hair line. (See Farkas' Figure IX-5, XIII-5.)
The coordinates of this point is; since the exact functions
are not determined as of :
[0, fnY(tr), fnZ(tr)]
WHERE:
X=0 because of the centerline function or definition.
fnY(tr) is a function using the desired body overall height
( mm ) as a factor. Some of the other facial height ratios
and measurements are expected to be terms or factors within
the function : fnY(tr) = mm - v_gn + tr_gn
fnZ(tr) is a function using certain factors, among them being
head depth calculations, measurements, or other
determinations. The exact expression is suspected to be:
fnZ(tr) = .953 * g_op where the constant must be replaced
with a functional variable as of .
