If you don’t want to play Zak the robot, maybe you just want to buy him. (Or rent-to-own?)
An anonymous GURPS-loving person, referenced only as “a friend” by Jachra on the GURPS Forums, made a set of conversion rules to use the GURPS 3e Robots book to make robots for GURPS 4e. That’s useful because 3e Robots contains rules that allow you to specify robots as equipment instead of as a character.
I’m going to build Zak as a TL10 robot (one TL behind) as he is going to appear in the Deeps of Lyrae campaign on a backwater planet where robots are unknown. (I realize this is not the TL that I will use for the PC/NPC designs for Zak — each design is a little different as I am trying things out.
Important: The narrative description of this design (with a picture) is here.
Here we go:

- Two spindly legs that appear undersized ending in flat metal feet
Software:
I had to be pretty creative with software as the system described in GURPS 3e Robots is based somewhat on advantages that no longer exist in GURPS 4e.
Firmware:
This is meant to represent unchangeable software. In GURPS 3e Robots these are called “involuntary” programs. We could call this something analogous to the Operating System and BIOS?

ROM Chips:
This is meant to represent unchangeable software. In GURPS 3e Robots these are called “involuntary” programs. Even if the robot can’t change its software, that doesn’t mean someone else can’t change the software.
I thought I would distinguish ROM from Firmware and divide them into “chips” because I foresee a scenario where the players might want to change some of this programming and perhaps it could be a minor puzzle for them to figure out how to do so. (Remember in my setting robots, and therefore knowledge about robots, is rare.)
Let’s give this stuff a cool name like “DDB40 Obedience Restrictors.”

Data Bank:
The data bank is intended as “voluntary” software under the Robots 3e definition. It also might be fun for the players to try to figure out how the robot works or how to modify it. I came up with some zany names for the software packages to add color.

Addendum: House Rules
To make this design fit my imagined robot, I had to make these changes:
- House Rule: (deviates from Robots 3e p. 29): The optimal number of arms with integral tools is not 4, it is 2.
- House Rule: (deviates from Robots 3e): legs at TL10 are not required to be any proportion of the torso’s volume in order to support it. Advances in materials means that legs can be very small/thin.
IMAGE CODA: Generated with DALL-E 3.
