	abstract = {Collaboration between humans and robots presents a variety of difficult problems. In a practical sense, collaborative robots need to be safe to work with, capable of adapting to varied human behavior, and to react at human time scales. Additionally, however, for collaborative systems to really work they must also be able to communicate their needs, to express their intentions, and to understand communicative cues from their collaboration partners. Without the ability to express itself clearly to others, collaboration with a robot will never feel as fluid and intuitive as collaboration with a human partner. Even in the case that the robot is able to work more efficiently or safely than a human partner, it may never be accepted by humans who struggle to understand the robot{\textquoteright}s decisions or state.

We propose that the design of effective collaborative robots and their behavior will need to follow a human-centric process informed both by observations of how humans collaborate and communicate when working together as well as frequent user studies to evaluate what elements of human behavior can be transferred to and clearly replicated by collaborative robots.},
