The Problem:
Drones counting as characters means they can be subject to the same statuses and conditions that can affect characters, one of which is being knocked Prone. Prone is a status that can only be cleared by giving up one's standard move in order to stand up, but the tricky issue is that drones do not have a standard move to give, meaning once knocked prone they essentially have to remain that way.
However the Hydra's OROCHI drones do state that they "move independently on your turn," but it's not spelled out explicitly that this counts as a standard move for the purpose of standing from prone (it's fair to argue that it counts, but it's still left somewhat up to interpretation).
The Solution:
If OROCHI drones in particular are meant to be able to use their movement to stand from prone, then it may be worth clarifying in the text of the OROCHI drone ability itself, i.e. instead of "They can move independently on your turn" stating "They can make a standard move on your turn"
