  Robotic systems that are intended to augment human capabilities commonly
require the use of semi-autonomous control and artificial sensing, while at the
same time aiming to empower the user to make decisions and take actions. This
work identifies principles and techniques from the literature that can help to
resolve this apparent contradiction. It is postulated that augmentative robots
must function as tools that have partial agency, as collaborative agents that
provide conditional transparency, and ideally, serve as extensions of the human
body.
