>>25754182the designers added sexually detracting design elements like large breasts and a large ass to compensate for the lack of (simulated) reproductive organs. it's too keep you from wanting to fuck the robot because it doesn't have that feature available
imagine if the robot was designed as a loli with a small stature, perfectly flat cunny chest, ass, and small delicate hips, but DIDN'T have any sexual functions. you would just constantly want to fuck it but would be unable to, making the design just a constant giant blueball.
large tits and ass are to discourage fucking the robot, because the robot doesn't have the right parts to enable fucking it.
(i couldn't find any loli roboco art so here's a picture of rushia)
