2. ASSEMBLY

Connect the two bases with 10mm or 12mm M3

bolts. This pivot point is for the y-axis of the eye

motion and the eyelids.

Place the servo in position and screw it in with

some 4mm or 6mm M2 screws (Figure

A

). This

serves as the actuator for the x-axis motion.

Attach the y-axis arm to the sub-base with a

4/5/6mm M3 screw, and attach a servo horn on

the third hole from the center using a 4mm or

6mm M2 screw, as shown in Figure A. Check to

make sure the orientation of everything is right.

Start building the x-axis assembly (Figure

B

)

by screwing the forks into the eye-adaptors with

4/5/6mm M3 bolts. The fork holes should be

oversized so
