Our vision is to put a robot in every office and home. To achieve that vision we believe robots must have four primary characteristics -- be useful, familiar, capable of building relationships, and multi-purpose. We believe humanoid robots are too prone to the "Uncanny Valley" effect and can be disturbing to many people, not pleasant. Humanoid robots may therefore be less likely to achieve a level of comfortable familiarity and develop the relationships with humans required for mass use. We’re strong believers that robots will form different relationships with humans than humans do with each other -- more along the lines of the relationship between a pet and its owner.
