CTE Pneumatics

Introduction

CTE Pneumatic commands will only work with the CTE Pneumatic parts. You will need to manually import the CTE module in order for this to work:

from cte import *

The CTE Pneumatic system uses an air pump and solenoid to control compressed air for moving cylinders. It can turn the pump on or off and extend or retract cylinders through code.

This page uses cte_pneumatic as the example CTE Pneumatics name. Replace it with your own configured name as needed.

Below is a list of available methods:

• extend – Extend a cylinder.

• retract – Retract a cylinder.

• pump_on – Turn on the air pump.

• pump_off – Turn off the air pump.

• pump – Set the on or off state of the air pump.

• installed – Returns whether or not a CTE Pneumatic Solenoid is connected to the Brain.

Constructors – Manually initialize and configure a CTE Pneumatics Solenoid.

• Pneumatic – Creates a CTE Pneumatic Solenoid.

extend

extend extends a cylinder.

Usage:
cte_pneumatic.extend(cylinder)

Parameters	Description
cylinder	The cylinder to extend: CYLINDER1 CYLINDER2 CYLINDER3 CYLINDER4 CYLINDERALL – All 4 cylinders

retract

retract retracts a cylinder.

Usage:
cte_pneumatic.retract(cylinder)

Parameters	Description
cylinder	The cylinder to retract: CYLINDER1 CYLINDER2 CYLINDER3 CYLINDER4 CYLINDERALL – All 4 cylinders

pump_on

pump_on turns the air pump on.

Usage:
cte_pneumatic.pump_on()

Parameters	Description
	This method has no parameters.

pump_off

pump_off turns the air pump off.

Usage:

cte_pneumatic.pump_off()

Parameters	Description
	This method has no parameters.

pump

pump turns the air pump on or off.

Usage:

cte_pneumatic.pump(state)

Parameters	Description
state	The air pump state: True – Turn the air pump on. False – Turn the air pump off.

installed

installed returns a Boolean indicating whether the CTE Pneumatic Solenoid is connected to the Brain.

• True - The solenoid is connected to the Brain.

• False - The solenoid is not connected to the Brain.

Usage:

cte_pneumatic.installed()

Parameters	Description
	This method has no parameters.

Constructors

Constructors are used to manually create Pneumatic objects, which are necessary for configuring a CTE Pneumatic Solenoid.

Pneumatic

Pneumatic creates a CTE Pneumatic Solenoid.

Usage:
Pneumatic(smartport)

Parameter	Description
smartport	The Smart Port that the CTE Pneumatic Solenoid is connected to, written as Ports.PORTx where x is the number of the port.

from cte import *

# Create a CTE Pneumatic Solenoid in Port 1
cte_pneumatic = Pneumatic(Ports.PORT1)
