Robotics

Question 1

what is artificial intelligence?

Answer 1

Computers that can think / make decisions / problem solve / learn / adapt / simultaneously process large amounts of information

Question 2

how might artificial intelligence be used in design?

Answer 2

• simulations allow extensive testing and evaluation without a prototype
• could suggest modifications to products being designed
• autonomous manufacturing systems which can respond to problems / make adjustments to allow production to continue
• voice recognition systems help improve communication between designer and computer system

Question 3

range of tasks carried out by robots

Answer 3

welding, spray painting, moving components around the factory, pop rivets, insert screws, quality checks, applying adhesive, assembly, routing, laser cutting, drilling and milling

Question 4

Advantages of robot use

Answer 4

• speed of movement improves productivity
• accuracy means increased complexity is ok
• reliability of repetitive accuracy
• flexibility, can be re programmed
• reduced labour requirements
• can work 24/7
• remove workers from safety hazards
• can undertake difficult and undesirable tasks
• can carry heavy loads
• cnc machines and robots combine to create FMS

Question 5

Disadvantages of robot use

Answer 5

• reduced employment
• high set up cost
• the need for training
• decreased morale of workers
• robots not as responsive as workers
• maintenance costs
• breakdowns can affect the production lines
• compatibility issues, no robot language
• costs of health and safety restrictions i.e. fences

Question 6

AVG (automatic guided vehicles)

Answer 6

-used to move materials in a factory environment
often guided by:
-floor mounted reflective strips
-floor embedded radio wire
-laser guided
-gyroscope guided
-GPS guided

Question 7

Advantages of AVG compared to manual moving

Answer 7

• parts are retrieved at the precise time they are required
• can run 24/7
• reduced employment costs
• reduced error
• improved safety

Question 8

disadvantages of AVG compared to manual moving

Answer 8

• high set up costs
• lack of flexibility
• faulty damaged components can go undetected
• puts people out of work
