Procedure turn/hold required on this approach?
If you start the procedure at ROBUD and your clearance does not include "cleared for straight in approach", then you are expected to do a procedure turn in the hold. In real life the first thing to do in such situation would be to query the controller "confirm we are cleared for straight in approach", they are very likely to forget it also.

In my opinion, this is an example of an error on the FAA chart, which is missing noPT annotation on the leg from ROBUD to MOFTE. That annotation is present on a Jepp chart. I've seen these kind of errors in the past and FAA is usually pretty good in correcting them, so go ahead and ask them at Aeronautical Inquires.
