Pneumatic

Introduction

The VEX EXP Brain can control the CTE Pneumatic system using methods from the Pneumatic class. These methods allow the Brain to control the pneumatic pump and extend or retract pneumatic cylinders.

For the examples below, the configured CTE Pneumatic Solenoid will be named pneumatic_1 and will be used in all subsequent examples throughout this API documentation when referring to Pneumatic class methods.

Below is a list of all available methods:

Actions – Control pneumatic cylinders and the pneumatic pump.

• extend – Extends a pneumatic cylinder.

• retract – Retracts a pneumatic cylinder.

• pump_on – Turns the pneumatic pump on.

• pump_off – Turns the pneumatic pump off.

Setters – Turn the pneumatic pump on or off.

• pump – Turns the pneumatic pump on or off.

Constructors – Manually initialize and configure the CTE Pneumatic Solenoid.

• Pneumatic – Create a CTE Pneumatic Solenoid.

Actions

extend

extend extends a pneumatic cylinder.

Usage:
extend(cylinder)

Parameter	Description
cylinder	The cylinder to extend: CYLINDER1 CYLINDER2 CYLINDER3 CYLINDER4 CYLINDERALL — Extends all cylinders

# Extend the first cylinder
pneumatic_1.extend(CYLINDER1)

# Wait 2 seconds
wait(2, SECONDS)

# Retract the first cylinder
pneumatic_1.retract(CYLINDER1)

retract

retract retracts a pneumatic cylinder.

Usage:
retract(cylinder)

Parameter	Description
cylinder	The cylinder to retract: CYLINDER1 CYLINDER2 CYLINDER3 CYLINDER4 CYLINDERALL — Retracts all cylinders.

# Extend the first cylinder
pneumatic_1.extend(CYLINDER1)

# Wait 2 seconds
wait(2, SECONDS)

# Retract the first cylinder
pneumatic_1.retract(CYLINDER1)

pump_on

pump_on turns the pneumatic pump on.

Usage:
pump_on()

Parameters	Description
	This method has no parameters.

# Turn the pneumatic pump on
pneumatic_1.pump_on()

pump_off

pump_off turns the pneumatic pump off.

Usage:
pump_off()

Parameters	Description
	This method has no parameters.

# Turn the pneumatic pump off
pneumatic_1.pump_off()

Setters

pump

pump turns the pneumatic pump on or off.

Usage:
pump(state)

Parameter	Description
state	The state to set: True turns the pneumatic pump on, and False turns the pneumatic pump off.

# Turn the pneumatic pump on
pneumatic_1.pump(True)

# Turn the pneumatic pump off
pneumatic_1.pump(False)

Constructors

Pneumatic

Pneumatic creates a Pneumatic System.

Pneumatic(smartport)

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

# Construct a Pneumatic System "pneumatic_1" with the
# Pneumatic class
pneumatic_1 = Pneumatic(Ports.PORT1)
