Yes

As long as you don't want to use the existing voltage regulator that
is intended to driver peripheral and servo loads.

But, if you are talking about servo power only, why not plug a 6V
battery into +SP and Gnd and call it a day? You certainly don't need
sub 1% regulation for servos.

The power design of the R board is quite flexible. Well thought out...

I think Dan's point is to be absolutely certain that the pinout on the
R board for the 3d regulator actually matches a 7805 and not one of
the others. I don't have an R board so I can't check. But for servo
power I wouldn't be adding a regulator anyway.
