Mr Arthur
Aims of Lesson 1
1. What is an Automated System
2. Advantages of Automated Systems over Manual Systems
3. Examine different types of Automated Systems
Automated Systems
An Automated System is where you provide the input, the machine or computer carries out the process and provides you with the output
Everyday Life? Washing Machine Video Recorder Dishwasher Microwave
Automated Systems in Industry
Car Manufacture Coke Production Automated Milk System Aircraft Manufacture Spray Tanning
Advantages of using Automated Systems
1. They can carry out tasks much faster

Sensors and Feedback
A sensor is a device which detects a physical quantity Light sensor Heat sensor Bump sensor Movement sensor Sound sensor
The signals which a sensor sends back to the computer is called feedback

Implications of Auto Systems To discuss AGVs and Guidance Systems
Social Implications
Jobs losses Reduces morale having robots Need to retrain for other jobs Work 24/7 Less injuries for workers Improved working conditions More social time
Technical Implications
Program machine to move slowly Fit sensors and provide feedback Cover moving parts Cover the battery and processor Safety guidelines in place
Economic Implications
High running costs Higher initial cost Cheaper in the long run Larger output = more money Repair costs More accuracy = less waste Expensive to replace Less employee wages = larger profits Redundancy costs

Autonomous Guided Vehicles
An Autonomous Guided Vehicle is a vehicle that is programmed by a computer system to move about a factory floor delivering parts to work stations or removing waste.
AGVs are controlled in 2 different ways A Light Guidance System is used where the AGV follows
a painted line along the factory floor A Magnetic Guidance System is where the AGV follow
the magnetic pulses from a wire under the factor floor
Remotely Operated Vehicles
Remotely Operated Vehicles are used in hazardous environments where it is not safe for humans to go. They can be used for bomb disposal, under water and space exploration.
The vehicle is equipped with a television camera, which relays a picture to the operator controlling it at a safe distance.

Systems To discuss AGVs and Guidance Systems To discuss ROVsToday’s Lesson Programming Robots
Programming Robots and AGVs
Robots are normally controlled by a computer program, which is made up of instructions written in a high level language
The robot may also be trained using the lead through method
Programs are stored on ROM chips. These are a more expensive way of storing programs but they retain their information if the power is switched off and load up much faster
Powering Robots and AGVs
Robots and AGVs are normally powered by motor or may sometimes be powered by a battery

Computer Aided Design
Computer Aided Design
Computer Aided Design is a way of using a computer system to design the structure or appearance of an item on a screen.
They are often used for the design of the following items Car Design Kitchen Design Housing Cartoon Animation
CAD requires different types of input devices, with most drawings often created using a Graphics Tablet.
The drawings are sometimes too big to send to a printer and a plotter is often used to get a hard copy

Simulation
Simulation is where you use a computer system to model a real life situation.
Examples training a pilot to land a 747
Jet, training army staff to drive a
tank testing loading conditions of
a bridge driving a Formula 1 car Rollercoaster simulator
Advantages? Much safer for training
purposes Cheaper than doing the real
thing Practice different situations
that may not happen

Virtual Reality
Virtual Reality is a method of reproducing the outside world digitally within a computer system. To take part in virtual reality, the user wears a headset, with earphones and goggles, together with data gloves.
Virtual reality allows a user to project him or herself into the computer-generated world and move freely within it.
Analogue Signals Most electrical signals, like Mr
Haggarty singing into a microphone is analogue. Light, Heat, Movement
Analogue signals from a sensor vary continuously between 2 limits
Computer can only process digital signals i.e. 1s and 0s
An Analogue to Digital converter is required to convert the A signal to D for processing
An interface could be used to convert the Analogue to Digital signal

Embedded Systems
An embedded system is a computer system inside another, larger piece of equipment, like the computer system in most modern cars or in a mobile phone or in a microwave
The embedded system are often used to control critically important systems, like the car ignition or cooking times

Expert Systems
An Expert System is a special computer program which can apply hundreds of rules or facts that have been programmed by a human expert.
Expert system programs can diagnose your health problems, give you legal advice or help you find out what is wrong with your car’s ignition system.
Analogue to Digital Conversion
An interface is part of a computer system that allows different devices to communicate with the processor, compensating for any differences
An Analogue to Digital converter is required to convert the analogue signals from the sensor to digital signals that the computer can process.
