HOW IT WORKS
a23 MECHANICAL ARM
The mechanical arm
attaches to both the servo
hub and the DC motor shaft,
and oers lots of leverage
for pushing, pulling, and
throwing.
To attach the mechanical
arm to the servo hub,
use two of the #6 screws
(included) and a Phillips-
head screwdriver (not the
purple screwdriver). Be sure
to screw through the holes
on the servo hub.
To attach the mechanical
arm to the DC motor, line up
the flat edge of the DC motor
shaft with the flat edge of
either of the flat-edged holes
on the mechanical arm.
The two large holes on the
end are perfect for holding
pens and markers in place.
