are in the front of ‘tool boxes’ to give
their respective size scale.
The kits state that the included
screwdriver is all that is required,
however I found the use of tweezers,
needle-nose pliers, a small bench vise,
and even masking tape sure made
assembly easier using my ‘fat’ fingers.

to pick up an individual screw or nut
and place it in the required hole.
Careful reading of each small step

of the assembly is very important. The
Bioloid kit manual described the
assembly strictly in a series of visual
black and white pictures. Sometimes I
had to look over the whole page just
to realize what the next step would
be. The Hovis manual has more
assembly pages and all were
annotated in English. Their manual
depicts each plastic bracket in bright
green, and the Herkulex servos and
the tiny mounting brackets were in
black. It was sometimes difficult to
clearly see the mounting of these tiny
black brackets as they were mounted
to a black servo. Both company’s
manuals were very well printed, but I
did find a few errors.
Things to Watch
With very detailed kits, not only
must you read the manual carefully
but take care to identify locations,
orientations, and just “where did this
wire go to?” type of questions. It is
very important that you verify the
servo’s horn position before mounting
the joints to them. There are faint
marks on the Herkulex servos but it
was easier to verify positioning on the
spline. There were a few instances of
differences of a pictured green plastic
part for the Hovis than what was in
the kit, but it didn’t matter.
There were some furnished
