In 2017 my dish washer has a computer and my next fridge will make the grocery list. I don't know if its a drone but voice command and the senses and software to keep from crashing into things seems like something a human would put in a cargo unit. How else do I steer it?
This is an old game right? Does everything have a machine spirt? Sorry wrong game, a computer in it?
I didn't say it was clumsy...
But no, you're thinking of Warhammer 40k, sort of. Actually there are some rules for adding computers to guns and pretty much anything else, that... and a generally good nature... is why I'm not actually objecting.
I just had the painful insight that you earlier asked if your trunk floats. I assumed you meant in the tradtional fashion... if you tossed it into water. No wonder it seemed such a weird question.
So to properly answer: Adding one device (such as a grav belt, or a computer) to another unrelated device (such as a footlocker) is as simple as just paying the price for both. Normally a Grav Belt is 100,000, which is a bit odd, since your probe drone (I went with the cooler version btw, you can thank me later) only costs 15,000 and yet has a 'grav belt', and the cheap version is 2000 and STILL has a grav belt. So discounting a Grav Belt built into an object seems... more than fair. Presumably the cost of the belt is proportional to how much it has to carry and how mobile it is (a personal grav belt can carry more than your body-weight and lets you fly around the sky like a weirdly non-aerodynamic plane... your trunk, presumably, simply hovers gently and moves at a fast walking pace, hence... cheap.)
Supposedly a gun with a computer and the right software can shoot people for you (er.... okay), and even improve your own shooting (er... not so okay! Bad TOUCH!!!), etc...
Where things start getting wonky is when you start making all these drones 'smart', as the Core rules don't really handle that at all, the default setting assumes low-robotics, and the Robot supplement seems to assume Emergent AI and full sentience to include robot-religions and other cray-cray. Since I LIKE the lack of hordes of rules, its pretty easy for me to default to 'what is playable' and let it ride from there... I can assume at least some people know how to program fake-smart robots for users who don't want to spend all day playing 'remote control' or worrying about being turned into a duracell battery.
