You need to connect the wires from the
battery to the wires from the motor. Push the red
wire from the motor and the black wire from the
battery case into one of the metal eyelets. Press
a terminal cap into the eyelet to keep the wires in
place. Put the black wire from the motor and red
wire from the battery case into the other eyelet.
Add the other terminal cap.

Take a body ring and position it over the body ring that is attached at
the motor case end of the body plate. Align the holes in the two rings and
insert two bolts into the holes. Put nuts on the bolts and tighten them.
Repeat step 9 for the other body ring, but this time put a straw
attachment on the bolt before inserting it into the rings.
COMPLETE BODY RINGS

Push the long leg onto the peg under the battery case, and secure with a
screw.
Push the short leg onto the peg on the outside of the body ring nearest the
axle. Secure with a screw.
Push a bendy straw onto each straw attachment on the body ring. Push a
gripper hand onto the other end of each straw.
Place a ring on one end of a wire into a peg
on one eye base plate. Attach the wire to the
eye base plate with a screw. Repeat for the
other eye. Peel off the cover sheet at the back
of the moving eyes and attach them to the eye
plates. Using screws, attach the other ends of
the wires to the pegs on the end of the body
plate near the battery case. Bend the wire to
achieve the shape you like. If you would like to make spirals, wind the wires
around a pen as illustrated, and then slide the pen out.

Congratulations! Your Tin Can Robot is now complete. Stand your Tin Can Robot on end and switch on the
motor. The Robot will walk along, wobbling from side to side, making a buzzing noise. You can create
different walking movements by adjusting the angles of the cams to each other.
E. ROBOTIC MONSTER
You can make the robot walk horizontally,
too. Remove the tin can. Swap the wires
so that the two red wires are in one metal
eyelet, and the two black wires are in the
other. Remember to replace the terminal
caps. (If you do not swap the wires over,
the Robot will walk backwards!)
Place the robot down horizontally as shown. It is now a robotic monster!
Slide an empty, clean tin can into the body rings. You may need to loosen the nuts on the rings to get
the can in. Tighten them again afterwards.
Insert a ‘AA’ 1.5 volt battery into the battery case. The negative terminal of the battery (the flat end)
goes against the spring in the battery case. If the motor runs, flick the switch to turn it off. Attach the
battery case cover with a screw.

is called resonance. You can hear it if you put your ear near the can. If you take the can out of its rings,
you’ll hear that the Robot’s sound gets much quieter.
Musical instruments Most musical instruments make use of resonance to make their sounds. For example,
the sound box on a guitar makes the music louder because air resonates inside it. And air resonates inside
the tube of a trumpet when it’s blown. See the effect for yourself by blowing gently across the top of an
empty plastic bottle until the air inside resonates.
The sea in a shell If you put a large shell to your ear, you can hear the sea! It’s not really the sea. The
whooshing sound is sound from the environment around you resonating in the shell.
Robot movement Engineers have developed several ways for robots to get around. Most roving robots have
wheels or tracks. But some have two legs, and walk like humans. Walking is a very difficult problem for
robot engineers to overcome, and reliable walking robots are still being developed. However, some robots
have been made to jump and even perform somersaults.
F. TROUBLE SHOOTING
If the motor does not run
• Check that the wires are connected properly at the terminals.
• Check that the battery is inserted the correct way round (see step 16).
• Check that you are using a fresh battery.
• Check that the gear wheel and worm gear are interlocked.
• Check that the gears are lubricated. You may add lubrication to the gears through the small hole at the
back.
G. FUN FACTS
How does it work? The battery provides electricity to the motor, which turns the worm gear at high speed.
The worm gear acts as a reduction gear. It turns the axle gear at low speed. The pieces of plastic on the
ends of the axle are called cams. A cam is simply a circle with a hump. As the cam turns, the hump moves
around it. When the motor switched on, the cams make each side of the Robot lift in turn, causing the
Robot to make walking movements.
Using cams The Robot’s cams turn the rotational movement of the axle into up and down movement. Many
machines contain cams that do the same job. For example, in a car engine, cams open and close the
valves that let fuel into the cylinders and exhaust gases out.
Tin can sounds The movements of the motor, gears and cams create vibrations that move through the
Robot. More vibrations come from the leg as it rubs along the ground. The vibrations are passed to the
soda can, and the air inside the can. They bounce around, making the buzzing sound louder. This bouncing

Look at the body plate. On one side are two metal eyelets. Slot two body rings to this side. Their
pegs go into the holes which are about two centimeters from either end of the plate. Fix each ring
with a screw inserted from the other side of the body plate.
Turn the body plate over so that it stands on the rings, with the
motor and gear housings nearest you. The battery case fits on the
flat area of the body plate furthest from you, with the switch
nearest the gear housing. First, gently thread the wires through the
two smaller square holes in the body plate. The black wire goes
through the right-hand hole, and the red wire through the left-hand
hole.
Lower the battery case onto the body plate so that the pegs in the battery case slot into the holes
in the body plate. Be careful not to trap the wires between the battery case and body plate. Fix the
battery case in place with two screws through its base. Do not put a battery in the case yet.

Gently thread the wires from the motor through the square holes in the body
casing. Thread the red wire through the right-hand hole and the black wire through the left-hand
hole. Slot the motor into the motor housing.
Put the axle into the axle housing so that it lies in the cut-outs in the top of housing. The gear
wheel on the axle should interlock with the worm gear on the motor shaft. Lubricate the gears with
grease. (Cooking oil from kitchen will serve the purpose).
Drop the motor/axle cover over the motor and axle and push it
down onto the four pegs on the body plate. Fix the cover in place
with four screws.
Carefully but firmly push a cam onto one end of the axle. Push
the other cam onto the other end of the axle so that the hump on its
cam points in the opposite direction to the first cam.
