Tadashi's goal in creating Baymax was to help improve healthcare around the world, basically wanting nothing more than to use his creation and genius for the better of humanity. To provide him with his programming, and overall personality, Baymax was given a special chip with Tadashi's inscriptions, which makes him the lovable robot he truly is.

As programming would have, Baymax is instantly summoned by the sound of distress, and can only deactivate once his current patient states "I am satisfied with my care."
