ROBOTSBy Joaquin

Law Zero: A robot will not hurt humanity, or, allow humanity to come to harm.

Law One: A robot may not injure a human being, or, allow a human being to come to harm, unless this would break a higher law.

Law Two: A robot must obey orders given it by human beings, except where such orders would break another law.

Law Three: A robot must protect its own existence as long as such protection does not break another law.

Confusing huh?

The Three Laws of Robotics(Plus Law Zero)

INTRO

A robot is a man made machine that copies the actions of a creature or human. To be a robot it has to get information from it's surroundings and do something physical like move objects. Robots are also great at doing repetitive (boring), precise, movements. The reason we use robots is because it's either cheaper, easier, or the only way to do things. In this slide show we will talk about the different parts of robots and how they work.

All robots need a power source. Most robots either have a battery or they plug into the wall. Batteries have really strange names carbon-zinc, lithium-ion, lead-acid, nickel-cadmium, nickel-hydrogen, silver zinc and alkaline to name a few. Hydraulic robots also need a pump and pneumatic (operated by air) robots need an air compressor or compressed air tanks. Also they can be solar powered.

Sensor System

Robots can't normally smell or taste things, but they can "see" an object or "feel" it. Some robots can "hear" as well. The simplest way for robots to see is using a photo-electric cell. It makes a robot convert "light energy" into electrical energy. E.g. If a robot looks at a tool on a table, the light will bounce off it and will be turned into electrical currents which will be transmitted into it's brain.

The touch sense can be made by robots as well with these thingy's called "tactile sensors". The simplest kind of tactile sensor is a switch that closes when it comes into contact with an object. When a finger touches an object, it closes, making an electrical current go to the brain.

Other sensors include temperature, altitude and pressure.

BRAIN SYSTEM

A robot brain is what makes it ‘think’. It commands the

rest of the body to do what it is programmed to do and

operate how it’s supposed to. It's usually a type of

computer which is used to store information about the

robot and it’s surroundings. The brain system also called

the control system contains programs, data algorithms,

logic analysis and a bunch of other technical things that

make the robot do it’s job.

SOME ROBOTS YOU MIGHT HAVE HEARD OF

Just as your heart produces the pressure to make blood go round your body, a battery or generator produces the pressure or force to push electrons (really small stuff) around a circuit which creates voltage. If you think electrons in the wires move fast, your wrong. Believe it or not, when you turn on the light at home the electrons in the wires move at the same speed as a minute hand! Voltage is measured in volts, (V) but the flow of electrons is measured in Amperes (Amps) (A).

Extra Facts

Most robots are in car factories.

People who make robots are called roboticists

Robots are not able to think or make decisions

The first true robot toy was produced in Japan.

Robots are used a lot in surgery because of their precise movements.

So that’s it. I hope you liked it!!!!
