The Zeroth Law of Robotics, the most important Law for Giskardian robots, was phrased multiple ways:
- 'A robot may not harm humanity, or, through inaction, allow humanity to come to harm.'
- 'Humanity as a whole is placed over the fate of a single human.'
- 'A robot must act in the long-range interest of humanity as a whole, and may overrule all other laws whenver it seems necessary for that ultimate good.'
Originally created by R. Daneel Olivaw and R. Giskard Reventlov, the Zeroth Law would later be installed in a whole host of Giskardian robots, most importantly humaniform Dors Venabili.
