For the Rogue Trader scenario I'm working on, I needed four non-combat robots.
These models are very old Gamma World miniatures by Grenadier. They appealed to me because they are from the same era as my other models and fit in very well stylistically. They were essentially identical with separate left arms. I set about converting a few to add variety and create a narrative. The tracked robot has a servo-claw from a tech-priest model... no idea what the track bit was from! The command robot has a comm pack from the Imperial Guard Cadian sprue.
In my scenario, these robots are tasked with the recovery of valuable (?) cargo that may have survived the crash of an Aquila Lander fleeing from an Imperial patrol in orbit. Conditions on the planet play hell with comms so I'm going to limit the ability of the robot tech to change their orders - he must be within 12". However, he may relay orders an additional 12" from the command robot (the spiffy yellow guy), increasing the possible range up to 24". If anything happens to Hart, Marko Steelknife may broadcast a recall command that will order the robots to return to Natasha's Luck, but that is the only command he can issue.
Point Values were calculated using the rules on page 58 of the Rogue Trader rule book. As non-combat robots, they are not armed with range weapons but may be ordered to charge (if Tech Hart is in range) and they will automatically defend themselves in close combat if attacked. The Fusion Torches equipped on the red robots are treated (and priced) as Power Swords.
I'm full steam ahead on this project and the next few weeks will be mostly dedicated to the models I need to complete this scenario!
