Pneumatics

Introduction

The pneumatic class provides control for the CTE Pneumatic system, which uses an air pump and solenoid to control compressed air for moving cylinders. This class enables precise control of pneumatic actuators in automated workcell applications.

Note: CTE Pneumatic commands require the CTE module. Import it using using namespace cte;.

Class Constructors

pneumatic( 
  int32_t index );

Class Destructor

Destroys the pneumatic object and releases associated resources.

~pneumatic();

Parameters

Parameter	Type	Description
index	int32_t	The Smart Port that the CTE Pneumatic Solenoid is connected to (e.g., PORT1).

Notes

• CTE Pneumatic commands will only work with the CTE Pneumatic parts.

• You must manually import the CTE module: using namespace cte;.

• The system can control up to 4 cylinders individually or all at once.

Example

using namespace cte;

// Create a CTE Pneumatic Solenoid in Port 1
pneumatic ctePneumatic1 = pneumatic(PORT1);

// Turn on the pump and extend cylinder 1
ctePneumatic1.pump_on();
ctePneumatic1.extend(cylinder1);

Member Functions

extend

Extends a pneumatic cylinder.

Available Functions

void extend( 
  cylinderType id );

Parameters

Parameter	Type	Description
id	cylinderType	The cylinder to extend: cylinder1 cylinder2 cylinder3 cylinder4 cylinderAll – All 4 cylinders

Return Values

This function does not return a value.

Examples

// Extend cylinder 1
ctePneumatic1.extend(cylinder1);

// Extend all cylinders
ctePneumatic1.extend(cylinderAll);

retract

Retracts a pneumatic cylinder.

Available Functions

void retract( 
  cylinderType id );

Parameters

Parameter	Type	Description
id	cylinderType	The cylinder to retract: cylinder1 cylinder2 cylinder3 cylinder4 cylinderAll – All 4 cylinders

Return Values

This function does not return a value.

Examples

// Retract cylinder 2
ctePneumatic1.retract(cylinder2);

// Retract all cylinders
ctePneumatic1.retract(cylinderAll);

pump_on

Turns the air pump on.

Available Functions

void pump_on();

Parameters

This function does not have parameters.

Return Values

This function does not return a value.

Examples

// Turn on the air pump
ctePneumatic1.pump_on();

pump_off

Turns the air pump off.

Available Functions

void pump_off();

Parameters

This function does not have parameters.

Return Values

This function does not return a value.

Examples

// Turn off the air pump
ctePneumatic1.pump_off();

pump

Controls the air pump state.

Available Functions

void pump( 
  bool state );

Parameters

Parameter	Type	Description
state	bool	The air pump state: true – Turn the air pump on false – Turn the air pump off

Return Values

This function does not return a value.

Examples

// Turn the pump on
ctePneumatic1.pump(true);

// Turn the pump off
ctePneumatic1.pump(false);

installed

Returns whether the CTE Pneumatic Solenoid is connected to the Brain.

Available Functions

bool installed();

Parameters

This function does not have parameters.

Return Values

Returns a Boolean indicating whether the solenoid is connected to the Brain or not.

• true if the solenoid is connected to the Brain.

• false if the solenoid is not connected to the Brain.

Examples

// Check if the pneumatic solenoid is connected
if (ctePneumatic1.installed()) {
  // Pneumatic system is ready
  ctePneumatic1.pump_on();
}
