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.

• 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.
