Disabled pressure safety requirements
Hi everyone,
For our robot we are using a pneumatic system in order to run our arm that holds the totes. We saw that there is a safety requirement that the robot should have no pressure in the compressor when it is disabled. However, our robot doesn't have a digitally accessible valve, only a manual valve for letting the air out of the system. Would this meet the requirement in order to have all the pressure as 0 if we manually release the valve as we take the robot off the field? Additionally, if it is needed to have a digital pressure release during disabled, how would you recommend we do this? We don't currently have the hardware for a digital valve, and are unsure if a second solenoid is the best way to go. Currently the only way we can release the pressure is by actuating the arm repeatedly which would probably a worse safety hazard since that would open and close our arm mechanism. Thanks for your help, Team 8. |

The compressor cannot run when disabled. But, you don't have to bleed the air. Pressure can be stored while off. There does need to be a manual valve as you have described. The valve does have to vent ALL pressure in the system. |

Here is the rule that applies. You are clearly allowed to pre-charge your air system.
