Unless you're running her without FUA/Huohuo and are really desperate for the energy regen I don't see how because she doesn't get much out of it otherwise.
1st ult opening:
Bronya's signature is to ensure her to ult by the end of turn 1, to charge up 80 energy, you need skill+ normal attack+3 ally attack(20+35+4) x1.34=80.6. Otherwise you have need spend 2 SP to make sure her ult 70x1.194=83.4
Otherwise you either waste her 100% advancement on middle of turn 2 or her energy easily.
2nd ult energy requirement:
Even with Fua team, to charge up 160 energy, you needs allies to perform
(1)62 attack hits to charge up 160(ult right away)
(2)50 attack to charge up 125 energy full during ult.(Robin uses E than Ult again)
(3)36 attack (Robin uses 2 E than 2nd Ult again)
Everytime Robin get hit, reduce requirement by 2 count
with bonus 10% ER,
you need allies to
(1)57 attack
(2)44 attack
(3)33 attack
Everytime Robin get hit, reduce requirement by 3 count
