Chapter 8 Eyelids And Eyes Left And Right - Robotronics Pluggie Robot Operating Manual

CHAPTER 8 Eyelids and Eyes Left and Right

The eyelid and eyes left and right movement is accomplished by three servo motors in the
Character or upper robot. 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 with the
other circuit boards on the front of the robot. A diagram for this board is located in the
Appendix. 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.
New Auto Blink Feature
To turn the auto blink on/off: Move the red switch 13 toward you and hold for 3 seconds.
This will turn it off or on. The blinking will be random until you turn it off.
Surprise
The same switch 13 on the RC will also move both eyelids up, giving you a surprise look.
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.
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 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
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 on the main board. Make sure that these wires are connected well at the
servo board and main board.
Troubleshooting Eyes
If it is disconnected, reconnect according to the eye servo board
