User Manual
6. Some extra pen holders are provided for you. With these you
can extend the arms and add more pens to make even more
colourful patterns. You could add ball-point pens or coloured
pencils instead of felt-tip pens. Please note: ask an adult's
permission before you use other pens. They might wear out
quickly because of the vibrations.
7. How about organising a Doodling Robot gala? Put two or three
Doodling Robots on the same sheet of paper. Watch how they
bump into each other and create interesting patterns. You could
also put objects on the paper for the Robots to bump into.
8. Remove all the pens and turn down the arm ends. Doodling
Robot becomes a vibrobot that slides across smooth surfaces.
F. TROUBLE SHOOTING
If the motor does not run:
• Check that you are using fresh battery.
• Check that the battery are inserted the correct way round in the battery case.
• Check that the terminal caps are in properly, and that all four wires are touching the metal terminals.
• The vibrations can make the pens and arms move. Stop this by tightening the bolts in the arms a little.
G. HOW DOES IT WORK?
The batteries provide electricity to the motor, which turns the weight at high speed. The centre of gravity
of the weight is off centre – it is not in line with the motor's shaft. As the weight moves around it pulls the
baseplate in the opposite direction all the time, it makes the motor and baseplate vibrate in tiny circles at
high frequency. It also makes the pen nibs vibrate up and down on the paper. As the nibs jump off the
paper, the circling vibrations make them move along. If the nibs did not jump up and down, friction with
the paper would stop them from moving.
H. FUN FACTS
• Industrial robots that move, cut and join materials can be programmed to draw on paper.
• Swiss scientists have built a robot that takes a picture of a person’s face and uses it to draw a sketch
of the person using a pen on a robot arm.
• Turtle educational robots can be programmed to draw geometric shapes using simple programming
language, such as FORWARD, BACK and TURN.
• Vibrations are used in many industrial machines. For example, vibrating conveyors move materials such
as powders by making them jump up and down at high frequency.

A. SAFETY
1. Adult supervision and assistance are required at all times.
2. This kit is intended for children of ages over 8.
3. This kit and its finished product contain small parts which may cause choking if misused. Keep away from
children under 3 years old.
4. To prevent possible short circuits, never touch the contacts inside the battery case with any metal.
B. USE OF THE BATTERY
1. Requires one 1.5V "AA" battery (not included).
2. For best results, always use a fresh battery.
3. Make sure you insert the battery with the correct polarities.
4. Remove the battery from the kit when not in use.
5. Replace an exhausted battery straight away to avoid possible damage to the kit.
6. A rechargeable battery must be removed from the kit before recharging.
7. Rechargeable batteries should be recharged under adult supervision.
8. Do not attempt to recharge non-rechargeable batteries.
9. Make sure that the supply terminals in the battery case are not short circuited.
D. ASSEMBLY
1. Examine the baseplate. The underside is the side with the battery
case. There are two slots for the motor on this side. Push the motor into
the slot in the centre of the baseplate, spindle first. Make sure that the
small metal ring around the motor's spindle fits right into the hole in
base of the slot.
2. Fit the motor cover over the motor, with the square side over the wire
connections. Secure the cover with two screws.
3. The weight has a small hole on its underside. Push the small hole
over the motor's spindle.
4. The Robot Doodler has three arms connected to the rim of the
baseplate. Push one end of an arm support over a hole in the edge of the baseplate. Secure the support
with a nut and bolt. The arm should be tightly attached to the plate but you should still be able to turn it
from side to side. Attach the other two arm supports to the other holes on the baseplate.
5. Hold two halves of a pen holder together and slot the narrow ends into one of the arm supports. Push
a bolt through the holes in the pen holder and the arm support and put a nut on the bolt. Tighten the bolt
until the joint is tight but can still move. Add a pen holder to the other two arm supports.
6. Then add an arm end to the end of each arm, and secure them with nuts and bolts.
7. Now you need to connect the wires from the battery to the wires from
the motor. There are two terminal holes on the underside of the
baseplate. Push the bare ends of the red wire from the battery case and
the red wire from the motor into one hole. Push a terminal cap into the
hole to trap and connect the wires. Repeat with the black wires in the
other terminal hole.
8. Put the transparent cover over the weight and secure it with two
screws into the holes in the baseplate.
9. Insert a 1.5 V "AA" battery into the battery case. The negative
terminal (the flat end) of the battery goes against the spring in the
battery case. If the motor runs, switch the switch to turn it off.
10. Push a felt-tip pen into the pen holder in each of the arms. The nibs of the pens must point down, so
they must be on the underside of the baseplate (where the battery is).
Congratulations! Your Doodle Robot is ready to draw!
E. OPERATION
Always cover your working area with sheets of newspaper so that the
working surface is not stained by ink if the Doodling Robot leaves the
drawing paper. Place a large sheet of drawing paper (or newspaper if
you like) on the working area. Using the adhesive pads provided, put
strips of paper along the edges of the drawing paper, creating a border.
This will stop the Doodling Robot from leaving the paper.
1. To draw a�circle line pattern: Check
that the arms are all pointing straight
outwards and are level, so that the
pens are vertical. Remove the pen
caps and switch on the motor. Gently
put the Robot Doodler onto a large
sheet of paper and let it go. It should
move in a circle, drawing three
coloured lines. When you are happy
with the pattern the Robot Doodler
has drawn, lift the Robot off the paper. Switch off the motor and replace
the pen caps. You can also fix one of the pens to the drawing paper with
an adhesive pad. The Robot will revolve around this pen, drawing larger
circles with its other two pens.
2. To draw straight line patterns: Turn
the pen holders so that they are all
parallel, and tilt the pens slight
outwards (see diagram). The Robot
should run along a straight line,
drawing lines as it goes.
3. Try installing the motor in the other slot (which is off centre in the
baseplate). Your Doodling Robot will tend to spin in a more
unpredictable way than when the motor is in the centre, and will draw
a more random pattern.
4. Try adjusting the height of the baseplate by moving the pens up and
down in their holders. Doodling Robot will spin faster if the baseplate is
higher and slower if it is lower.
5. Try different combinations of angles of the pen holders. You might
make Doodling Robot draw some new and interesting patterns. There
are endless possibilities.
