The Three Laws of Robotics(Plus Law Zero)Law Zero: A robot will not hurt humanity, or, allow humanity to come toharm.Law One: A robot may not injure a human being, or, allow a human beingto come to harm, unless this would break a higher law.Law Two: A robot must obey orders given it by human beings, exceptwhere such orders would break another law.Law Three: A robot must protect its own existence as long as suchprotection does not break another law.Confusing huh?
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 its 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 its 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.
Power Supply All robots need a power source. Most robots either havea battery or they plug into the wall. Batteries have reallystrange names carbon-zinc, lithium-ion, lead-acid, nickel-cadmium, nickel-hydrogen, silver zinc and alkaline toname a few. Hydraulic robots also need a pump andpneumatic (operated by air) robots need an aircompressor or compressed air tanks. Also they can besolar powered.
Robots cant normally smell or taste things, but they can "see" anobject or "feel" it. Some robots can "hear" as well.The simplest way for robots to see is using a photo-electric cell. Itmakes a robot convert "light energy" into electrical energy. E.g. If arobot looks at a tool on a table, the light will bounce off it and will beturned into electrical currents which will be transmitted into its brain.The touch sense can be made by robots as well with these thingyscalled "tactile sensors". The simplest kind of tactile sensor is a switchthat closes when it comes into contact with an object. When a fingertouches an object, it closes, making an electrical current go to thebrain.Other sensors include temperature, altitude and pressure.
BRAIN SYSTEMA robot brain is what makes it ‘think’. It commands the rest of thebody to do what it is programmed to do and operate how it’ssupposed to. Its usually a type of computer which is used to storeinformation about the robot and it’s surroundings. The brain systemalso called the control system contains programs, dataalgorithms, logic analysis and a bunch of other technical things thatmake the robot do it’s job.

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).Robots Circuitry
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.Extra Facts
