Pneumatic

Introduction

The VEX EXP Brain can control the CTE Pneumatic Solenoid using blocks from the Pneumatics category. These blocks allow the Brain to control the pneumatic pump and extend or retract pneumatic cylinders.

Below is a list of all blocks:

• set pneumatic cylinder — Extends or retracts a pneumatic cylinder.

• set pneumatic pump — Turns the pneumatic pump on or off.

set pneumatic cylinder

The set pneumatic cylinder block extends or retracts a specified pneumatic cylinder in a pneumatic system.

  set [Pneumatic1 v] [cylinder1 v] to [extend v]

Parameter	Description
device	Which Pneumatic Solenoid to use, configured in the Devices window.
cylinder	Specifies which cylinder to control: cylinder1 cylinder2 cylinder3 cylinder4
state	Sets the cylinder position: extend retract

Example

  when started
  [Extend cylinder 1 at the start of the project.]
  set [Pneumatic1 v] [cylinder1 v] to [extend v]
  [Retract cylinder 1 after 2 seconds.]
  wait (2) seconds
  set [Pneumatic1 v] [cylinder1 v] to [retract v]

set pneumatic pump

The set pneumatic pump block turns the pneumatic pump on or off for a specified pneumatic system.

  set [Pneumatic1 v] pump to [on v]

Parameter	Description
device	Which Pneumatic Solenoid to use, configured in the Devices window.
state	Sets the air pump’s state: on off

Example

  when started
  [Turn the pneumatic pump off at the start of the project.]
  set [Pneumatic1 v] pump to [off v]
  [Wait 2 seconds before turning the pneumatic pump on]
  wait (2) seconds
  set [Pneumatic1 v] pump to [on v]
