SR-75 Series Overview

The SR-75 series of sentry droids is pro-

duced by Standard Robotics Inc. with
Hughes Microtechnologies acting as pri-
mary supplier for the onboard sensor pack-
age. The original SR-75A production unit
was hailed as a major advance in the com-
pany’s droid product line - cheap, effective
and easily maintained.

Increasing request from customers regard-

ing custom enhancements for the armor of
the units resulted in a production upgrade in
the middle of the block 20 production line.
Block 25 and higher units (designated SR-
75B models) featured better armor plating
in response to customer input.

The success of the line eventually resulted

in a much anticipated military order. This
model would be based on the SR-75B frame
but would feature better armor, additional
weaponry and an artificial intelligence
upgrade. A single FSD (Full Scale
Development) prototype was created for
this order. After initial testing it was decid-
ed to enhance the unit’s offensive capabili-
ties by pushing a new Standard Robotics
Inc. prototype laser carbine into production
for use on the military order. The military
version was introduced on the production
line at the block 45 stage and became
known as the SR-75C series. The SR-75C
maintained the mounted laser pistol on the
unit’s right forearm, and the new laser car-
bine was mounted on the droid’s torso to the
left of the video system.

The models are easily distinguishable by

the color of their armor plating. The original
block 5, 10, 15 and 20 series of units were
white, the block 25, 30, 35 and 40 units
were a blue-gray and the block 45 military
order was a smoke-gray color per a request
in the military contract (the original FSD
unit was black.)
