6.1 automated systems

Question 1

what are automated systems comprised of

Answer 1

sensors, microprocessors, actuators

Question 2

how do components of automated systems work together

Answer 2

• sensors provide measurements to microprocessors
• microprocessors process and make decisions based on predefined rules
• decisions made by microprocessors typically result in instructions to control actuator and make physical changes
• COMPONENTS USED TO MAKE FEEDBACK LOOP WHERE OUTPUT FROM AUTOMATED SYSTEM AFFECT FOLLOWING SET OF INPUT VALUES RECEIVED FROM SENSORS

Question 3

what are advantages of automated system

Answer 3

+ operations carried out faster than human operator
+ safety in hazardous environments
+ long-term cost savings
+ efficient use of resources leads to increased productivity
+ more consistent results

Question 4

what are disadvantages of automated systems

Answer 4

• upfront costs more expensive
• require more time to test and calibrate
• highly specialised and ongoing maintenance
• result in significant job losses
• can only respond to specific situations within certain parameters (not as flexible as humans)

Question 5

what are disadvantages of robots

Answer 5

• initially very expensive to set up
• replaced manual jobs, unemployment
• do not cope as well with unexpected situations requiring human intuition
