<R01> Energy used by FIRST Robotics Competition ROBOTS, (i.e., stored at the start of a
MATCH), shall come only from the following sources:
B. Compressed air stored in the pneumatic system, stored at a maximum pressure of 120 PSI
in no more than four Clippard Instruments tanks. Extraneous lengths of pneumatic tubing
shall not be used to increase the storage capacity of the air storage system.

<R75> “Working” air pressure on the ROBOT must be no greater than 60psi. All working air must
be provided through one primary Norgen adjustable pressure regulator.
A. All “working” pneumatic components (e.g. valves, cylinders, rotary actuators, etc.) must
be downstream from this regulator.
B. Only the compressor, relief valve, pressure switch, pressure vent valve, pressure gauge,
storage tanks, tubing, and connecting fittings may be in the high-pressure pneumatic
circuit upstream from the regulator.
C. Pressure gauges must be placed in easily visible locations upstream and downstream of
the regulator to display the “stored” and “working” pressures.
D. If the compressor is not included on the ROBOT (under the provisions of Rule <R74>),
the regulator may be located on-board or off-board, provided all other pneumatic rules
are satisfied. Note that if the regulator is kept off-board the ROBOT with the
compressor, then only low-pressure (60psi or less) “working” air can be stored on the
ROBOT.
<R76> The relief valve must be attached directly to the compressor. Teams are not allowed to
adjust the 125-psi relief valve. The valve has been calibrated prior to shipping.
<R77> The Nason pressure switch must be connected to the high-pressure side of the pneumatic
circuit (i.e. prior to the pressure regulator) to sense the “stored” pressure of the circuit. The
two wires from the pressure switch must be connected directly to a digital input and ground
port on the Digital Sidecar, and the cRIO Mobile Device Controller must be programmed to
sense the state of the switch and operate the relay module that powers the compressor to
prevent over-pressuring the system.
