13. Add the moving eye to each of the claws (parts L and M), then add the claws to the front of the body. Also attach the rear legs (parts
P and Q) to the rear of the body.
14. Operation: Insert a 1.5V AAA battery into the battery holder, making sure the flat end of the battery rests against the spring in the
holder. Add the battery cover and secure it with a screw. Adult supervision is required.
15. If the Sun is out, slide the switch to solar-powered mode and twist the solar panel to face the Sun. The Hybrid Crab Robot will operate
under solar power.
16. Switch to battery powered by sliding the switch to battery mode where sunlight is not available. When the robot is not in use, move the
switch to solar-powered mode to power off.
E. TROUBLESHOOTING
If the crab does not move in solar-powered mode or battery mode:
• Check that you have made the correct connections on the terminal blocks (see section D, step 7). • Check that the bare metal on all the
wires is in contact with the metal terminals. • If the gears do no have enough lubrication, apply cooking oil or lotion to help the system run
smoothly. Friction between the gear wheels will affect the performance of the motor.
If the motor does not run in solar-powered mode:
• The sunlight may not be strong enough. Adjust the angle of the panel so that it directly faces the sun. • Check that the gears are
lubricated.
If the motor does not run in battery mode:
• Check that you have a fresh battery and that the battery is inserted into the battery holder the correct way round. • Check that the gears
are lubricated.
F. HOW IT WORKS
The solar panel turns light energy from the Sun into electricity. This electricity, or electricity from the battery, powers the motor. Inside the
robot's body, gears transfer the movement of motor to the wheels on the from and back of the body, and also reduce the speed of turning
between the motor and the wheels. The leg mechanisms turn the rotation of the wheels into side to side movement of legs. The legs
move in turn, which makes the robot walk sideways.
G. FUN FACTS
• The word 'hybrid' means a mixture of two forms of power. The Hybrid Crab Robot uses a mixture of solar power and battery power. A
hybrid car uses a mixture of engine and battery power. • Solar-powered cars are not powerful enough for everyday driving, but
experimental cars have travelled 3,000 kilometres in special races. • Crabs have ten legs. The rear pair of legs is designed for swimming
and the front pair has claws that the crab uses to catch and eat prey. • Crabs can walk forwards and backwards, but they find it easiest to
walk sideways. • Walking robots with four or more legs, like the Hybrid Crab Robot, are very stable because one leg can be lifted at a time
without the robot falling over.
