Chapter 9 Eyes System
CHAPTER 9 Eyelids and Eyes Left and Right
The eyelid and eyes left and right movement is accomplished by three servo motors in
Patches. When the switch on the radio control is activated, this signal is sent to the radio
control receiver in the robot. The micro-controller in the robot decodes this signal and a new
signal is sent to the eyes servo board. The eyes servo board is located on the underside of
the top of the robot. To see it, the top would need to be removed and the top turned on its
side. The wires connected to this board take the signal to the servo itself and operate the
shaft of the servo motor to turn clockwise or counter-clockwise for opening or closing. The
rotation of the servo motor shaft is coupled to the eyelid and eyeballs with a servo arm and
then an eyelid rod.
Troubleshooting Eyes
An eyelid or the eyes left and right does not operate:
1. Check the linkage from the servo motor. Look for the servo arm off the servo shaft or
the eyelid off the ball link.
2. Follow the wires from the specific servo motor with the problem. The wire will run to the
eye servo board. If it is disconnected, reconnect according to the eye servo board
diagram. If the servo does not work correctly (wrong direction), try one of the other
outputs on the eye servo board.
One of the eyelids is at a different level than the other:
1. If the eyelid rod is bent, bend it back into position.
2. If the servo saver arm (white and metal arm interconnecting the servo and the rod), is
solid and secure the position of the eyelid can be positioned to match the other eyelid.
To remove the servo saver arm, the set screw must be removed. The eyelid level can
be changed by altering the length of the eyelid rod or changing the position of the servo
saver arm on the servo motor shaft.
There is no operation of any of the eye functions:
1. The wires that bring the signal to the eyes servo board are gray and yellow. 5 volts
power are the black and red wires that connect to the eyes servo board. If these wires
are connected, follow them back to the board that they originate.
Wires originate at the Patches board.
