Robots were first built by Humans to improve their lives. It has gotten to the point now that robots outnumber Humans—or at least, voting humans—by one.
Robots in SocietyEdit
Robots can acquire wealth, marry, obtain jobs, consume resources, own property and live in robot societies. Each different facet of society in the year 3000 has some form of robot related - to human benefit or not.
Robots in Futurama seem to exist in conflict with the idea of form and function - to which present day industrial design strives. In the year circa 3000 robots consume high volumes of resources (Calculon's luxury Bel-air home) and inhabit land (Robot Arms Apartments). In society they can be found in all levels of society - in the gutter "jacking on" (getting stoned on electricity) and at the top (Hedonism bot appears to be very wealthy, commissioning artistic endeavours on a whim). There is however little social mobility as a robot's function is predetermined by its type.
There appear to be two main types, or castes, of robot:
Likely built by Humans, these robots are bound to their programming. They can be easily identified by the fact that their name often reflects their job. They are not all "laborers", per se, but they were built for a specific job, which they perform without question.
Possibly built by robots (evidenced by Bender's statement, "We can always build more killbots" (1ACV04)), these are free to do as they please, and in fact, many are homeless. They still seem to pay homage to Mom on Mother's Day, though. Their names tend to have little to do with their occupations.
