Sim

Sim was the term used by the robots on Verdus to refer to humans.

Sim was a contraction of 'simulated human'. They deemed the real humans which they encountered to be sims, as, contrary to their programming that humans were superior in every respect, the humans were weak, they felt pain and were not as intelligent as (some of) the robots of Verdus.

Commander Kidd was referred to as a 'childling'.
