It is fairly certain that we and Robustus both descended from the more gracile lines of Australopithecus but our line didn't have the big sagittal crests that Robustus and Australopithecus Boisei had (needed to attach those big herbivore jaw muscles to the top of the skull).
I agree with you on the brain development point. Even though Robustus probably had a very basic level of tool use they almost certainly never developed the use of fire or spoken language before they died out leaving no descendants.

The reason I used
A. Robustus as an example is that
Robustus is the sort of thing you get when you have a pre-human creature that subsists primarily on vegetable matter. You don't evolve a big brain that way. Considering what we did to this planet, maybe it would have been for the better if pre-humans decided
not to eat meat...
