Pneumatics are limited. A Robot’s pneumatic sub-system must satisfy the following criteria:
  • Teams may use a maximum of two (2) legal VEX pneumatic air reservoirs on a Robot.
  • Pneumatic devices may be charged to a maximum of 100 psi.
  • The compressed air contained inside a pneumatic sub-system can only be used to actuate legal pneumatic devices (e.g., cylinders).
  • The intent of <R17a> and <R17b> is to limit Robots to the air pressure stored in two reservoir tanks, as well as the normal working air pressure contained in their pneumatic cylinders and tubing on the Robot. Teams may not use other elements for the purposes of storing or generating air pressure. Using cylinders or additional pneumatic tubing solely for additional storage is in Violation of the spirit of this rule. Similarly, using pneumatic cylinders and/or tubing without any air reservoirs is also in Violation of the spirit of this rule. The intent of <R17c> is to ensure that pneumatics are being used safely. Pressurized systems, such as a Robot’s pneumatic sub-system, have the potential to be dangerous if used incorrectly. This rule ensures the safety of participants, and prevents potentially unsafe uses in the future. Another way of thinking of <R17c> is that pneumatics should only be used with pneumatics. Teams should not use compressed air as a means of actuating non-pneumatic devices such as screws, nuts, etc. For example, pulling a pin with a pneumatic cylinder is okay, but using air to actuate the pin itself is not.
