How to Build a Moral Robot

Whether it's in our cars, our hospitals or our homes, we'll soon depend upon robots to make judgement calls in which human lives are at stake.

In order to pull it off, they'll need to answer some important questions: How can we quantify the fuzzy, conflicting norms that guide human choices? How can we equip robots with the communication skills to explain their choices in way that we can understand? And would we even want robots to make the same decisions we'd expect humans to make?
