 VEX Robotics - Pneumatics Controls


To perform their function, pneumatic cylinders impart a force by converting the potential energy of compressed gas into kinetic energy. This is achieved by the compressed gas being able to expand, without external energy input, which itself occurs due to the pressure gradient established by the compressed gas being at a greater pressure than the atmospheric pressure. This air expansion forces the piston to move in the desired direction.

The pneumatic cylinders have 2 states. The Single Acting cylinder uses air to push in one of the states and a spring for return in the second state. The Double Acting cylinder uses air in both states; push and return.

You can connect the 3 pin connector of the Solenoid Driver to any of the ANALOG/DIGITAL Ports on the VEX Controller. The Black wire should be closest to the outside edge of the VEX Controller.  Likewise, the White wire should be closest to the Keyed Slot even though there is no key tab on the Solenoid Driver Cable. You can control the two states of the pneumatics by controlling the two states of a Digital Output. By sending a High (1) or Low (0) to the defined Digital Output that you have the Solenoid Driver connected to, you will be controlling the corresponding pneumatic cylinder. To change the state of a Digital Output of the VEX Controller, you must have a Programming Kit.

Use the diagrams below to assemble your pneumatic system. You must use an external pump (standard tire fitting) to pressurize the pneumatic system before use.


 VEX Robotics - Pneumatics Kit 1 - Single Acting Cylinders

Kit 1 is a complete pneumatics add-on for the VEX Robotics system.  The cylinders are Single Acting, meaning they use air pressure to extend the piston, and an internal spring to allow the piston to retract.    See Part List for kit contents.



 VEX Robotics - Pneumatics Kit 1A - Single Acting Cylinder Add-On

Kit 1A adds one Cylinder (Air Push, Spring Return) to Kit 1 or Kit 2. Cannot be used without Kit 1 or Kit 2.  See Part List for kit contents.



 VEX Robotics - Pneumatics Kit 2 - Double Acting Cylinders

Kit 2 is a complete pneumatics add-on for the VEX Robotics system.  The cylinders are Double Acting, meaning they use air pressure to extend and retract the piston.    See Part List for kit contents.



 VEX Robotics - Pneumatics Kit 2A - Double Acting Cylinder  Add-On

Kit 2A adds one Cylinder (Bi-directional) to Kit 1 or Kit 2. Cannot be used without Kit 1 or Kit 2.  See Part List for kit contents.



 VEX Robotics - Pneumatics Mounting Examples

There are many ways to mount the Pneumatics Cylinders, a few examples are shown below.
