Correct me if I’m wrong, but there is no rule in the pneumatic section for the robot build that states that the valves must fail open so the pressure in the cylinder is released after the power is off.

The valves must be open when the power is off so the vent valve can relieve all stored pressure. See rule R73.
<R73> The pressure vent plug valve must be connected to the pneumatic circuit such that, when manually operated, it will vent to the atmosphere to relieve all stored pressure. The valve must be placed on the ROBOT so that it is visible and easily accessible.
