F. TROUBLESHOOTING
If the motor does not run or move when it hits an obstacle:
• Check that you are using fresh batteries. Some rechargeable batteries may not be able
to produce enough electric current to keep the sphere turning when it hits an obstacle.
Remarks: It is recommended to use alkaline battery.
• Check that the battery is inserted the correct way round in the battery case.
• Remove the motor housing cover and check that all the connections between the wires
are OK. Also check that none of the connections between the wires are touching each
other, as this will cause a short circuit.
• Check that the cogs are sufficiently lubricated.
• Check if the two half spheres are screwed too tight and white spindle of the motor is
inserted into the square hole completely. This will add friction to the inner mechanism
when it is rotating.
If the motor keeps running when the switch is off:
• Remove the motor housing cover and check that none of the connections between the
wires is touching another.
Since the lubricating oil inside the motor may solidify after storing for a long period, it is
recommended that you remove the motor housing cover and rotate the worm gears several
turns by hand before playing with the robot. This ensures that the lubricating oil can be
spread evenly and the motor runs smoothly.
G. HOW IT WORKS
The gears slow the movement of motor, which makes the spindle turn more slowly than
the motor. The motor, battery and weight are all on one side of the spindle that turns the
sphere. This means that the centre of gravity of the motor assembly is off to one side.
With the motor switched off, the sphere always comes to rest with the centre of gravity
below the centre of the sphere, directly above where the sphere touches the ground. If you
roll the sphere to one side, it just rolls back again.
When you switch the motor on, the motor assembly turns inside the sphere. So centre of
gravity of the sphere moves to one side. This makes the sphere roll because it is unstable.
As the sphere rolls, the motor keeps turning the assembly, so the sphere keeps rolling.
The rubber ring grips the surface under the robot.
But how does the Robot Smart turn corners? The centre of gravity of the sphere is slightly
to one side of the rubber ring. This is why the sphere leans to one side. When the Smart
Robot hits an object, the sphere cannot move forwards. But because it leans to one side,
it turns to one side. It keeps turning until it can move forwards again.
H. FUN FACTS
• Smart Robot moves using a rotating sphere inside its case. Most mobile robots run on
wheels or tracks, and can go over rough ground.
• Bipedal robots are robots that walk on two legs, like humans. They need clever
mechanisms and computer technology to walk without falling over. Some bipedal robots
can even run and climb stairs.
I •
Robots that move around by themselves are called autonomous robots. They can't
normally see where they are going. Instead, they have touch sensors that detect when
g they bump into something.

D.ASSEMBLY
Follow these steps to assemble your Smart Robot. Numbers refer to the diagrams.
ASSEMBLING THE INSIDE MECHANISM
1. Identify the motor housing (it contains a switch and the battery case attached). Hold
the housing so the switch is facing down. Place the motor into the space in the housing.
It is recommended that you rotate the worm gears for several turns by hand to spread the
lubricating oil inside the motor evenly.
2. Before lowering the motor into place, carefully feed the wires from the motor down
through the holes in the motor housing.
3. Find the smaller of the two axles with cogs. Drop the end with the larger of the two
cogs into the white plastic bearing hole close to the end of the worm gear. The lower cog
should interlock with the worm gear.
4. Drop the metal end of the larger axle into the white bearing hole close to the corner of
the motor. Its cog should in terlock with the top cog on the smaller axle. Apply some
lubricant to the cogs. Cooking oil from the kitchen is suitable.
5. Keep holding the motor housing upright so that the axles do not fall out. Carefully lower
the motor housing cover into place. You may need to slight wiggle it so that the tops ends
of the axles fit into their upper bearings. If the cover does not fit into place properly,
remove it and make sure the axles and motor are still in their correct places.
6. Before screwing down the motor housing cover, slot the metal weight into place next to
the battery case. It only fits one way up. You'll have to lift the cover off the housing very
slightly to do this.
7. Make sure the motor housing cover is in place properly and secure it with screws.
8. Connect the black wire from the battery case to one wire from the motor. Make
connection to the shorter connection slot first (marked A). With the terminal cap, connect
the black wire from the battery case to one wire from the switch. After first pair of wires
connected, connect together the remaining two wires (one from the switch and one from
the motor) at the taller connection slot (marked Bl. Then secure the two connection tabs
with the long screw.
9. Insert an AA battery into the battery case. The negative terminal of each battery (the
flat end) goes against one of the springs in the battery case. 11 the motor runs, press the
switch once to turn it off. Add the battery case cover and secure it with a screw. Now test
everything by pressing the switch. The motor should run and the white spindle should
turn. If the motor does not run, see the troubleshooting guide below. Press the switch to
turn off the motor again.
• Some autonomous robots build up an electronic map of their surroundings by
remembering where they have bumped into things. Then they can move along without
bumping into things again.
• Automated guided vehicles (ATVs) are robots that work in factories, carrying things from
one place to another. They find their way by following lines drawn on the floor or
underground cables.
• Robot vacuum cleaners move around a room, sucking up dust as they go. When they
bump into an object, they turn round. Gradually they clean the whole room. Robot lawn
mowers cut grass in the same way.
• Each year robot soccer players play against each other in an international competition
called the RoboCup.

half sphere without the hole in it.
11. Fit the motor assembly into the half sphere so that the
white spindle on the assembly fits into the square hole in the
half sphere. Screw on the other half of the sphere so that
switch cover fits through the hole. Don't
over-tighten the screw thread.

Switch on the motor and push the sphere into the cover. Put the Smart Robot on a smooth surface
(such as a vinyl floor) and watch it go. Your Smart Robot does not run on carpeted flooring.
When it bumps into something, it automatically turns left or right and carries on going. Smart!
Try making a course using books for the Smart Robot to follow. You could even make a maze
to see if the Smart Robot can escape.
11 you keep the sphere hidden when you show the Smart Robot to your friends, it will be
a mystery to them how it moves and steers itself.
