A robot is a life form in The Sims 2. Although not strictly living, the robots are still considered to be beings. Optimum Alfred is the only robot in the game who your sim can interact with, although other robots can invade and need to be clobbered by the Ratticator. There are four possible types of robot invaders, PAL-8000, BAM-7000, POW-6000 and EEP-5000. PAL-8000 has the same interact picture as Optimum Alfred, despite appearing much lighter grey in person.
