are gas shocks legal?

Are gas shocks such as those used on lift gates and door openers such as to lift a tailgate of a van or suburban legal to use on a robot???

Yes, per <R106> and <R02> gas shocks/springs are legal.

Please see this thread for more discussion on gas shocks.

Also, Chief Delphi has a handy search function that allows you to look for threads that may answer your question, if you can’t find what you’re looking for in the manual. :slight_smile:

The manual answers this question in <R106>:

…For the purposes of the FIRST competition, closed-loop pneumatic (gas) shocks are not considered pneumatic devices, and are permitted additions to the ROBOT…

It’s really easy to find answers to questions like this if you search the manual, specifically section 8 - The Robot.

I’m going to close this, please see the above mentioned resources and check out the Official FRC Q&A, specifically here and here for more guidance.
