After you fix the robot, they start travelling the caravan merchant route.

Once you kill the scavenger, his Mr Handy starts moving on its own. Anyone know where it goes to? Canturberry Commons?

It probably continues the trader route until it meets its demise. I ran into them being slaughtered at an Enclave camp earlier tonight

Hm, I haven't met it in any of the trader routes after wasting the scavenger. It doesn't disappear from the game, though. I had it deactivated and it's still there deactivated. Wonder where it goes if I hadnt deactivate it.

First time i went to the Super duper mart the scavenger and the "house robot" was there.
I never fixed the robot becouse i wanted a trader and they were good company too, being guards at the super duper mart.

Well don't raiders spawn there?

Only once, then never again.

In the outside area they will, after three (ingame) days. Just not inside, at least not without a mod.

The stingy [bleep] only gave me 2 energy cells for fixing his robot!
