Limited Warranty
All robots and accessories have a limited one year warranty, which covers all parts and labor.
This period covers the normal burn-in for electronic components. Experience has shown that
this warranty period catches most component defects and other possible flaws. If you have a
problem, we are anxious to help. Our desire is to be certain you receive a quality product and
excellent service.
Warranty work is specifically limited to correction of defects by repair or replacement of faulty
equipment or parts. The robot shall be repaired or replaced at Seller's option. Equipment
returned to the factory for repair must have pre-authorization from our service department and
must be sent freight pre-paid, and will be returned freight pre-paid by UPS ground or common
carrier. If you need parts sent by air shipment you will be responsible to pay the additional
shipping charges.
In no event shall ROBOTRONICS, Inc. be liable for any incidental or consequential damages in
connection with or arising from the use of the robot.
The buyer is further responsible to ensure that proper and complete training be given to those
operating the robot system as all aspects of such operation cannot be covered in a brief manual
such as this.
In no event shall ROBOTRONICS, Inc. be liable for any incidental or consequential damages in
connection with or arising from the use of this manual or any procedures contained herein.
Record The Robot’s Vital Information
If You Have a Problem

Part 1 General Operating Instructions
CHAPTER 1 Getting Started
OPERATING TIPS AND SAFETY INFORMATION
ROBOTRONICS, Inc. robots are a unique and exciting tool in the hands of a skilled and trained
operator. The operator provides much of the excitement the robot conveys. The selection and
training of the operator should be done carefully, so as to provide a person with good judgment
and an outgoing personality. The operator is the single most important feature that the robot
has. Nevertheless, with a little practice anyone can learn to operate the robot and even those
with a shy personality can be very effective using the robot. It is important that you observe the
following safety guidelines. Include this in any operator training. Practicing with the robot and
having a program outline or script will help you have success the first few times out.
Keep the robot indoors with the cover on when not in use. This will keep the robot clean
and the color at its best.
Operate the robot with charged batteries in the transmitter and robot.
Never operate the robot out of line-of-sight.
The operator must have the radio control in their hands when the robot is on. If you
need to set the radio control down, turn the robot off first.
Always have a trained person posted near the robot to help in crowd control, and to protect
the robot from vandalism. This person is also available to answer questions and interact
with the robot.
Operating distance should never exceed 100 feet. When moving the robot through crowds,
the robot should be operated slowly and smoothly without any sudden changes of direction.
Walls, turns, and other obstacles are hazards to be avoided. Safe clearance should be
maintained between these obstacles and the robot.
Never leave the robot "ON" when unattended or in direct sunlight for extended periods of
time.
The robot is designed to be operated on hard, smooth surfaces and carpet. Avoid extra
deep shag carpet, dirt, gravel, or grass surfaces. Avoid steep inclines or large uneven
surfaces such as curbs, gutters, or uncovered electrical lines.
When using the robot on a stage, the area just in front of the stage should be clear of
children for at least 10 feet.
When attempting to operate the robot for the first time, do so in a large flat area without
obstacles. The operation of the controls should be done in a smooth, fluid manner. Avoid
jerking starts and stops or overreacting to the controls. When first practicing movement, it
is sometimes helpful to follow behind the robot, as robot movement will match stick
movement. (Controls respond opposite when the robot is facing the operator.)
The robot can be a highly successful tool for education and entertainment. Appropriate jokes,
stories and general conversation can be very effective. Children of all ages are strongly
attracted to the robot. They will talk to it, hug it, kiss it, and generally treat it as a good friend.
The smaller sized robots are very effective with children. They are light in weight and just the
right size to communicate with children. The most important ingredient to the use and effective
operation of the robot is common sense. The following instructions will help you get set up and
start using the robot.
Operating Hints

4
SETUP AND HOW TO OPERATE THE ROBOT
Step # 1
Read and study this manual completely before operating the robot.
Step # 2 Install and charge the batteries
To put the robot battery in the robot, tip the robot slightly to access the wing nut on the battery
door. This is located on the bottom back of the robot. After removing the wing nut, open the
door and lay the battery on the door with the battery wire harness running from left to right.
Attach the Battery connector (square black and red), to the robot connector (also square black
and red). Match red to red and black to black and connect them.
Note: The battery connector and robot connector look identical but they do connect together.
The battery door can now be closed and the wing nut put back on.
Be certain that the robot battery and radio control transmitter battery are fully charged before
operating the robot. Plug the RC battery charger into the side of the radio control and the
charging light will come on. The Pluggie battery can be charged in the robot or out. See the
Pluggie battery charging chapter.
Step # 3 Powering up
The radio control transmitter will be referred to as the “RC” in this manual. Turn the RC
"ON" first and then turn the robot "ON".
Important RC power up steps:
1. Put the four top switches in the forward
position.
2. Turn on the power switch. The display
will read switch error.
3. Move the top left switch (mp3) toward
you and the display will now come on.
Check that the RC battery voltage is 9 Volts or more. A fresh battery will show about 10 Volts
on the display. At about 8.5 Volts you will hear a buzzer indicating the battery is low and you
should charge the battery.
Tip: There is a hook on the RC that you can attach a neck strap to. You can use any RC or
camera type neck strap.
The "ON/OFF/RECHARGE" switch for the robot is located on the bottom left of the robot if you
are standing behind the robot. Push the switch forward to turn the robot on (On/Off positions
are labeled). The back position of the switch is the charging position.
Step # 4 Set the Volumes
Check that the volume of the voice and MP3 player are at the level that you want. These
volumes are located on the RC. You can also increase the master volume on the (Road Rage)
Amp inside the robot if needed. There is also a separate volume on the UHF wireless voice
receiver. To remove the cap, just grasp the bottom of the cap with your hands and give a short
MP3 Switch
Four Top Switches

5
pull up. The cap will pop off. If you want to remove the body, there are instructions under the
cap for how to do this.
Step # 5 Test all the functions
Test all of the robot's functions: voice both ways, cap, eyelids, eyes, MP3, siren, and drive
movement for proper operation. The voice modifier option can be turned on and off from the
RC with the voice switch. The robot is now ready to operate. Note: The MP3 player has
sounds on it but you will need to load your music on it. See the MP3 Player section.
Step # 6 Optional Accessories Setup
For information about these, see the optional accessories section. This includes options such
as the voice modifier and water squirter. These sections will give you step by step instructions
for setup and related diagrams.
Step # 7 Powering Down
To turn off the system, turn the main switch to the “OFF” position. Finally turn off the Voice
Transmitter, Receiver and the Radio Control Transmitter.
Step # 8 Charge the batteries again
Connect the Robot battery to the charger and bring it back to a full charge before leaving the
robot. This battery should not be left with a partial charge. The transmitter battery should be
charged if it is low.
All of the major functions of the robot each have a section in the manual with more
details and diagrams. Refer to these for more in depth information. The Appendix
has pictures and diagrams of where various parts are in the robot. These will help
you become familiar with where the parts are located and their function.

6
TRANSPORTING THE ROBOT
The vehicle that you use to transport the robot should have adequate shock absorption. Vans
and cars used for passengers would be the best. Transporting the robot in a trailer is not
recommended because trailers typically do not have the same level of shock absorption as a
car or van. A good rule of thumb to follow is that if the vehicle is adequate for transporting a
computer it should also be fine for the robot.
Double check that the body latches are secure. These two latch pins are found under the cap.
They push into the body latch blocks. The cap nut on the top of the cap rod should be tight
also.
Before strapping the robot to the cart, always put the robot cover on first. The robot cover
protects the body from getting scratches, keeps UV light off it, and helps the keep the cap on
during transport. Lift the robot on to the cart and place the wheels in the recess of the plastic
platform. Run the bunji cord around the robot enough times to hold it on tight.
You can leave the robot on the transport cart while the robot is in transit, to keep the robot from
rolling around.
!
CAUTION
If the robot is being transported in an open truck, the robot cover should be over the
robot and tied down tight around the bottom to prevent the cap from getting blown off.
If you do not have a cover you could take the cap off and put in the cab.

Part 2 Subsystems of the Robot
Functionally, the robot is made up of the following basic subsystems:
A. Radio Control System
B. Voice System
C. MP3 Player
D. Cap Function
E. Robot Battery Systems
F. Drive Motors
G. Eyelids and Eyes Left and Right
The systems block diagram found here and in the Appendix shows how the various
subsystems and their components are interrelated.
Following are explanations of each subsystem, some operating instructions, and trouble-
shooting hints where appropriate.

8
CHAPTER 2 Radio Control System
The Radio Control System consists of the control transmitter unit held by the operator and the
receiver with its associated components in the robot.
The Radio Control Transmitter converts movements of the control sticks and switches into a
coded radio signal, which is transmitted by radio to the Radio Control Receiver within the robot.
The signal is received and then decoded by the micro-controller, which is on the main circuit
board in the vehicle. The micro-controller controls functions based on what was sent from the
radio control transmitter.
Radio Control Operating Instructions
Refer to the diagram showing the radio control transmitter for the location of controls.
RC turn on steps:
1. Put the top switches in the position away from you.
2. Turn on the power switch. The display will read switch error.
3. Pull the very top left mp3 switch and the display will now come on.
You can now turn on the main robot power switch. It is necessary for the robot to always have
an operating signal when it is on. If there is no signal you will not have full control of the robot.
The right hand joystick controls movement of the robot's drive wheels. Pushing the stick
forward will cause the robot to move forward. Pulling the stick back will cause the robot to move
backward. Moving the stick to the right or left will cause the robot to turn to the right or left
respectively. Movement is fully proportional so any variation or combination of movement is
possible. The horizontal and vertical trim tabs to the left and below the joystick are for
centering and should be typically left in the center. The only time that you would need to move
these trims is if the robot started moving slightly on its own. In this case move them slightly
until the robot stops.
The left joystick controls the eyes and the eyelids. It also controls the mp3 volume up and
down.
For a detail of other functions, see the radio control diagram on the next page. All of these
functions are labeled on the radio control itself.
A charge plug is provided on the transmitter for recharging its internal battery. The transmitter
power switch must be in the off position before charging the batteries. A charge light on the
charger will come on while charging.
There is a RC battery (NiMH) provided with all robots. There is an extra Ni-MH battery provided
with the package. These will give you about 5 hours operation each.

The NiMH (Nickel Metal Hydride) RC Battery
The NI-MH RC transmitter battery will last about 5-6 hours on a full charge. Charge the battery
for about 14 hours. A charge jack is provided on the transmitter for recharging its internal
batteries. This round jack is located on the right side of the radio control. (See the radio
control diagram) The RC power switch must be in the off position when the charger is plugged
into it and must remain in the off position while charging. A light on the charger will be on,
when charging.
To avoid a RC battery going dead during a presentation, start the program with a fully charged
battery or be aware of how much charge there is left in the battery. If you have an extra battery
you can change batteries and keep going.
To install the NI-MH battery pack you need to take the battery cover off the RC. Disconnect the
RC battery and put the NI-MH battery in its place.
NI-MH RC Battery and Charger Specifications
NI-MH RC transmitter battery 9.6 Volts 1700mAH
NI-MH RC transmitter battery charger 11.6 Volts 130mA
Caution: Do not overcharge the batteries as this could cause permanent damage to the
transmitter batteries. (Doubling the normal charging time is the type of over charging that is
meant here, and the battery getting hot.) When the battery level needle goes in the red, the
robot should be turned off because the robot could act erratic without the transmitter signal.

Adapter for Charging an Extra NI-MH RC Transmitter Battery
If you have an extra NI-MH RC battery, you can charge this outside the RC. You may need to
do this while you are using the robot or if you need to charge both batteries at the same time.
The adapter needed to do this is in the control case or it is on your charger. It has a white
connector on one side and a connection on the other end that will go directly to your battery. If
the barrel adapter is currently on the charger, disconnect it and connect the other adapter. The
charging time is still about 14 hours.

CHAPTER 3 Wireless Voice System
The Voice System consists of two separate communication links. One link transmits the
operator's voice to the robot. When you speak into the headset mic, this audio goes to a
transmitter on your belt. This audio is transmitted to a receiver in the robot. The audio signal
then goes from the receiver through a mixing circuit on the main board. It is then is fed into the
amplifier which amplifies the signal through the robot's speakers.
The second voice link transmits the audio detected by the Mic element (located in the front of
the robot) to the 151 receiver (which is worn by the operator). This is amplified and sent to the
speaker in the operator's headset. When putting the headset on, adjust the earphone so that
you can hear well and the mic so that the volume is good.
Note: The operator’s transmitter and receiver can be worn next to each other. If you want
you can use a belt pack. The 151 Receiver antenna can be put in your pocket.

If needed, adjust the headset
frame so that the earphone and
the frame fit comfortably and the
earphone is against your ear.

15
How to Operate the Operator’s Transmitter
1. Open the battery door.
2. Use a 9 Volt alkaline battery and insert it according to the diagram inside the battery
compartment.
3. Place the headset on your head and adjust the microphone to approximately 1 inch from
your mouth. If needed, adjust the headset frame so that the earphone and the frame fit
comfortably and the earphone is against your ear.
4. Plug the mic plug from the headset into the top of the transmitter.
5. Move slide switches to the "ON" position.
6. On the UB4 there is a Volume input level adjust on the unit.
Frequency channel- Located on the back of the transmitter.
Function of the LED
When turning on the power switch, with a fresh alkaline 9-Volt, the battery light will blink on
momentarily and go out. This indicates that it is powering up and that the battery is good.
Because the light is a low battery indicator, when the light is on constant, this indicates the
battery is too low-below 7 Volts. Replace with a new alkaline battery.
Tip: The operator’s voice units both have metal clips that contact the posts of the
9-volt battery. These must be bent out from time to time to keep this contact good.

How to Operate the Receiver (in Robot)
There are two adjustments on the receiver. The volume is on the back of the receiver, which
you may set to the desired volume. On the UHF UB-10 you can change the volume on your
belt transmitter on the fly. The other adjustment is the sensitivity. This is factory preset to
maximum sensitivity. This effects how sensitive the receiver is to the transmitter signal.
Typically you would never need to adjust this. The only exception would be if you get squelch
when the transmitter is off. You can deal with this by simply turning on the belt transmitter
whenever the robot is turned on. You could turn the sensitivity down slightly but turn the
adjustment as little as possible, because adjusting it will affect the range.
Frequency label- Located on the side of the receiver.
Function of the LEDs
TX LED- This indicates that you are receiving a signal from the transmitter. On some units it is
a single TX light. On other units it may have an A or B that it will alternate between.
AF LED- This light indicates that audio is going through the receiver. It will flash as you speak
into your headset mic.
Tip: For best range extend the receiver antenna(s) as much as possible, not allowing it
to touch metal.
