Definition of an Automated Control System:
It is a group of elements that are combined to optimize a process working together
What is a variable in an automated control system?
It is a magnitude (light, sound, temperature, pressure) that can be measured to be used in a program
How many sensors (variables) does the LEGO NXT Robot have?
4: distance, pressure/contact, light, and sound
How many outputs does the LEGO NXT Robot have?
3: (A, B, C) for motors.
What kind of battery does the LEGO NXT Robot have?
9v rechargeable
What is the variable in an automated heating system?
temperature
7. What is the difference between open & closed loop systems?
open loop systems are simple sequences regulated by time.
What kind of system (open or closed loop) is a heating system auto-adjusted by the room temperature?
closed loop
What is the difference between a mechanism and an automatism?
An automatism is a mechanism with a control system attached to it.
What are the measurement unit options for the distance sensor?
2 options: inches or centimeters.
What does the "bumped" option mean for the contact sensor?
Wait for the sensor to be pressed and then released.
How is the value for a dark area when the light sensor is over it?
Lower values (<50)
What is the purpose of a loop in a program?
For a sequence to be repeated constantly.
What kind of automated systems program always has a loop in it?
Closed loop programs
15. What is a conditional in a program?
To divert a program depending on a variable value.
