Pneumatic Rotary Vane Actuators?

[ThirteenOfTwo]

Hello, fellow FRCers! I hope that this build season is finding you well and that you are in good position to finish your robots on time.

Our team was considering using a pneumatic rotary vane actuator on our robot (for reasons that will be revealed when we do our showcase thread). This is a part that has been legal in previous seasons, but the updated [R78] throws its legality into some doubt.

Here is an example of the kind of part we're talking about:http://www.mcmaster.com/#6508K142

A previous question in the Q&A, Q186, asked:

Is a pnuematic rotary cylinder the same as a pnuematic cylinder?

and received the answer:

For the purposes of FRC, yes.

Unfortunately, the question was rather poorly worded. There is no such thing as a "pneumatic rotary cylinder"--there are "pneumatic rotary actuators" that are cylindrical, but "pneumatic rotary cylinder" is not the correct term. Furthermore, there are two kinds of pneumatic rotary actuators: some vane type, others piston type. We think that the answer to [Q186] can be interpreted to mean that our part is legal, but we wanted to make absolutely sure.

I know what you're thinking. "Why ask Delphi? The Q&A is faster and more reliable!" Good idea, but we thought of that. We attempted to register our team's account with the Q&A, but it's been five days since the registration and we are still not allowed to submit any questions. Clicking on the "Team Questions" button on the Quextit site yields the message "your request is in pending state". Effectively, we cannot submit our question.

If you have a working Q&A account, we would be extremely grateful if you would submit the following question the the Q&A using said account.

The response to Q186 clarifies that a "pneumatic rotary cylinder" is a pneumatic cylinder under R78. There are multiple types of rotary pneumatic actuators. Are rotary vane actuators such as the following (http://www.mcmaster.com/#6508K142) considered legal pneumatic cylinders under R78?

If you are willing to submit the question, please do so, then post a message in this thread notifying teams that you have submitted the question (to avoid double-submissions) and identifying the question number (so that teams can follow it).

Thank you very much for your help. Good luck with the rest of build season!
