I think that Zelda vs Rob is likely an uphill battle more than anything, simply because he has a tool for almost everything and they are all kind of better than the tools we have to work with as Zelda, especially when it comes to aerials.
If you have exceptionally good reflexes you can reflect Robo Beam back at him and gain the upper hand in spacing/camping. You really need to force him to come to you and make him commit to things so I think it's a matter of out-camping him because if Zelda tries to approach it could end badly what with all the landing lag on our aerials >~>
Thankfully his Arm Rotor can't reflect Din's Fire, and Gyro should be equally as easy to deal with if you have good Nayru reflexes (Or even just grabbing it)
