Sure
Okay, the first of them seem to be some kind of security droid...
1: The Defective Droid
. . . In front of the castle entrance, a two-foot-tall droid is moving around in a circle and muttering: "Mite, Mite, Mite . . ." over and over. Its tractor treads have worn a three-inch-deep trench into the ground.
<no stats>
2: Guardians of the Castle
. . . Droids patrol the courtyard, which is just outside the castle. They resemble the droid that was moving around in circles, only these droids seem to be functioning properly. Each of these droids has a red crystal atop its casing.
. . . When a visible party member enters the courtyard, the nearest droid approaches the Character and says, "I am programmed to fire lasers at you unlessyou leave now! I would not give this warning, but my master has agreed to protect youths like yourself. Please leave immediately, or I will attack."
The droids are programmed to attack anyone standing in the courtyard who does not retreat within ten seconds of receiving the warning. However, the droids will only attack visible intruders who ignore the warning and remain in the courtyard. The droids cannot detect invisible intruders.
The droids are not programmed to respond to attacks from the air . . .

Special These droids obey anyone who uses the password. They do not respond to aerial attacks, doing no more than they are programmed to do. Droids outside of the defense walls circle in the same manner as the malfunctioning droid in Area 1.
Shall we call them "Droid, Guardian" since the encounter is entitled "Guardians of the Castle"?
Small Construct with 4 HD? The "laser" is probably a ranged touch attack.
