Automated and emerging technologies Flashcards
How sensors & microprocessors & actuators work together ? (5 marks)
- The sensor measures analog data.
- It will send to the ADC to convert analog data into electrical signals.
- Therefore, CPU can understand and compare the values with its pre-defined values.
- If the values exceed the range, DAC will convert electrical signals -> analog signals for actuators to act.
- If not, nothing happen :D
Advantages and disadvantages of automated system (4 marks)
ADS:
- reduced labour cost
- work 24/7
- less errors
DISADS:
- high initial costs
- High maintenance costs
Purpose of robotics (1 mark)
Design customs robots that meets with the criteria of the working tasks
Characteristics of robots (4 marks)
- Autonomously or semi-autonomously
- Contain electrical components ( microprocessors,actuators, sensors)
- Programmable (follow set of instructions)
- Have mechanical structure (framework that makes physical body)
Define Artificial Intelligence (1 mark)
- Computer systems that have similar intelligence as human to perform tasks.
How machine learning work? (3 marks)
- It can be supervised or unsupervised
- Supervised means the data will sort out manually
- Unsupervised means after the AI has adapted to the data inputted, it will automatically sort the data based on its knowledge
Characteristics of AI (3 marks)
Collections of data and rules: By feeding the AI with large amount of data and AI can process the data based on the rules
Ability to reason: Evaluate situation to make decisions
Ability to adapt: Change its own rules and data
Two types of AI ( 1 mark)
Machine learning and expert systems
Characteristics of expert systems ( 4 marks)
Knowledge base: Set of facts
Rule base: Set of rules
Interference: Based on the knowledge base, the AI can use knowledge from the knowledge base to make if statements and draw logical conclusions
User interface: Communication channel for input and output data
