Culprit #1: The Sheiff
Reason: He built the robots so tough, that his rescues would be allowed. But after Cool Steel attacked two guests, he turned them off. But when someone started medding round his lab, he turn Cool Steel back on.
Culprit #2: Gibby
Reason: To figure out how the Sheiff built his robots so he can build a theme park to impress Velma Dinkey.
Edit
Shaggy mentions that one of the foods he and Scooby see out in the desert are tofu burgers, keeping up the consistency that Shaggy, and Casey Kasem, is a vegetarian since the second season of Scooby-Doo, Where Are You?
Edit
The Sheriff: I shut 'em down after the last attack on some tourists, and they never would've been reactivated if you kids hadn't been meddling around my ranch house lab.
Fred: I wasn't meddling there.
Daphne: Me, neither.
Velma: Were you meddling?
Shaggy: Not me.
Scooby: Not Me.
Fred: For once, none of us were meddling.
The Sheriff: Well, somebody was.
