Killer robots

Have you ever woken from a sound sleep with the best idea ever and forgotten what it was before morning? Today I had the opposite experience: an idea so terrible that my subconscious refused to take responsibility for it and kicked me awake. By morning it was still there, burning like an ember in my thoughts - goblin phone sex operators.

 I have no plans to develop this idea, and no idea how to develop it if I wanted to.

Anyhoo, robots. The first few OD&D games played must have been real kitchen sink settings. I was interested to read that Gary G's Greyhawk had dinosaurs and androids as monsters the players could encounter. It’s a shame there aren't more robots in fantasy game supplements today. Here's some I've statted up, hoping to capture what would have been the 1970s aesthetic:

Roberzerker
A towering armoured beast with a single glowing eye, flailing claw-arms and a grating electronic voice shouting "DESTROY! DESTROY!" Usually set to guard an area or significant artefact. Won't leave the room its guard point is in unless it malfunctions (2 in 6 if damaged).

AC 6 [13], HD 5 (22hp), Att 2 x slam (1d6) or 1 x sonic (1d8, see specials), THAC0 17, MV 90' (30'), SV D10 W11 P12 B3 S14 (F5), ML 12, AL Neutral, XP 550, NA 1d3, TT D

Specials:
Sonic - The robot can make a straight-line attack affecting all opponents in targeted squares. Ignores armour, 3-round recharge.
Boom - a destroyed roberzerker explodes on 2 in 6, doing 1d8 damage to opponents in adjacent squares.
Mechanical - immune to all mind-affecting spells and conditions.

Spider
A dog-sized machine that lurks in the dark in high corners. Has 8 dim red lights as eyes. Will attempt to surprise or swarm opponents.

AC 8 [11], HD 2 (5hp), Att 1 x shock bite (1d6), THAC0 19, MV 120' (40'), SV D13 W14 P13 B16 S15 (T2), ML 12, AL Neutral, XP 35, NA 2d4, TT C

Specials:
Climb - a spider can crawl along walls or ceilings at its normal movement rate.
Backstab - as per Thief.
Mechanical - immune to all mind-affecting spells and conditions.

Scrapper
A man-sized construction which collects all kinds of metal for depositing in the hopper on its back, where it's crushed into ingots for storage. Not inherently hostile, but it wants the party's weapons and armour and will attempt to yank them off.

AC 8 [11], HD 3 (8hp), Att 1 x steal (see specials), THAC0 19, MV 120; (40'), SV D13 W14 P13 B16 S15 (T3), ML 9, AL Neutral, XP 65, NA 1d4, TT B

Specials:
Steal - on a successful attack, the scrapper will cut one item of the target's armour free, reducing AC by 2 points.
Mechanical - immune to all mind-affecting spells and conditions.

Hound
A security robot in the form of a lion-sized dog. Usually found walking patrols in an ancient facility, they attack without warning and fight to kill. 

AC 6 [13], HD 5 (22hp), Att 1 × bite (2d6), THAC0 17, MV 150’ (50’), SV D10 W11 P12 B13 S14 (F5), ML 12, AL Neutral, XP 425, NA 1d2 (2d4), TT D

Specials:
Backup - A hound signals for reinforcements when entering combat with the characters. 2d4 more hounds arrive in 1d6 turns.
Mechanical - immune to all mind-affecting spells and conditions.

Lifter
A huge robot on thick legs or tracks, designed for moving loads around. It may be hostile, or simply oblivious to the tiny characters.

AC 3 [16], HD 15 (67hp), Att 1 × crush  (4d8), THAC0 10, MV 80’ (26’), SV D8 W9 P10 B10 S12 (F8), ML 12, AL Neutral, XP 3,250, NA 1 (1d3), TT G

Specials:
Horn - operates every second turn, characters are deaf and unable to communicate via speech while it sounds.
Mechanical - immune to all mind-affecting spells and conditions.

Docbot
The one helpful robot on this list. Docbots are willing and able to perform medical treatment on human and demihuman characters. 3 in 6 chance it's run out of anaesthetic and attempts to inject a patient with a dried-up syringe before performing surgery. Doesn't speak the patient's language.

AC 3 [16], HD 1 (4hp), Att -, THAC0 -, MV 120’ (40’), SV D13 W14 P13 B16 S15 (T1), ML 12, AL Neutral, XP -, NA 1, TT B

Specials:
Heal - can use one full turn to heal a character by 1d6+1 hp. Can only treat the same character once every six hours.
Space age medicine - can treat conditions that would ordinarily require magical healing.
Mechanical - immune to all mind-affecting spells and conditions.

Note on treasure tables - robots don't carry cash, items or spells. In each case the treasure table given represents the value of the advanced metal scraps you can pick from a robot's wreckage. For each line on the table that indicates a non-money reward, roll again on the highest value money reward line.
