Autonomous Simbot Slaves?

[Rattlebox]

I love the inventing career, but was kinda disappointed with the Simbots in Ambitions. I remember a mod in Sims 2 that basically turned the Simbot into an autonomous slave, coming out to do chores around the house and then sleeping at a charging station when not needed. Is there anything similar for the Sims 3 Simbots yet?
