Eyes

CHAPTER 9 Eyelids

The eyelids movement is accomplished by one servo motor just behind the eyes. 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 behind the eyes. 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 with a

servo arm and then an eyelid rod.

Troubleshooting - Eyes

An eyelid 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.

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

is 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 Character board.
