PLTW CIM-Unit 1/Lesson 1.2/Control Systems(Part 1: Hardware)

A device or set of devices that are coordinated to execute a planned set of actions.

• control system

• computer

• calculator

• not sure

A video game controller allows objects on a screen or monitor to be manipulated, these controllers are also called by what other name?

• control devices

• manipulators

• remote controllers

• keyboard

A type of control system where:

• No direct connection between the output of the system and the conditions can be controlled

• Cannot compensate for unexpected forces

• An example is a sprinkler system

• Open Loop Control System

• Closed Loop Control System

• Sprinkler System

• Control System

A type of control system where:

• Provides the system with operation feedback

• Can compensate for conditional changes

• A example would be a thermostat whose heating or cooling is actuated based on the temperature sensed

• Open Loop Control System

• Closed Loop Control System

• Air Conditioning System

• Control System

Below are examples of an Open Loop Control System except for:

• electric iron

• electric hand drier

• bread toaster

• washing machine

Below are examples of a Closed Loop Control System except for:

• volume control on your stereo system

• electric iron

• water level controller

• air conditioner

In a VEX structure subsystem, metal components are directly attached together using what size screws and nuts?

• 8-32

• 4-32

• 6-32

• not sure

In a VEX system, these nuts have a plastic insert to prevent unscrewing.

• Nylock nuts

• KEPS nuts

• regular nuts

• mixed nuts

In a VEX system, these nuts have rings of “teeth” on one side to grip the piece being installed.

• Nylock nuts

• KEPS nuts

• regular nuts

• mixed nuts

In a VEX system, these nuts have no locking features at all and are not advisable to be used on robots constantly under motion.

• Nylock nuts

• KEPS nuts

• regular nuts

• mixed nuts
