I heard that you can make sims into robots in OFB, but I have no clue how. Is it really possible?

You can't turn actual Sims into robots, but you can build robots. Get a robot making bench in Buy Mode. Once your Sims has a high enough skill in robot making, they'll be able to build a Servo. This is the robot that you've heard of.

I don't know for sure if you can do this alternative, as I never tried it. But try this if you don't want to wait all that time to build up the skill. Put the bench on your community lot/home business and hire someone who has a high skill in robot making. When they arrive for work, assign them to the robot making bench.

oh, thanks, I was really confused about that for a while
