Future space exploration will demand the cultivation ofhuman-robotic systems, however, little attention has been paidto the development of human-robot teams. Current methods forautonomous plan creation are often complex and difficult touse. So a system is needed that enables humans and roboticsystems to naturally and effectively collaborate. Effectivecollaboration takes place when the participants are able tocommunicate in a natural and effective manner. Grounding, thecommon understanding between conversational participants,shared spatial referencing and situational awareness, are crucialcomponents of communication and collaboration. This paperbriefly reviews the fields of human-robot interaction andAugmented Reality (AR), the overlaying of computer graphicsonto the real worldview. The strengths of AR are discussed andhow they might be used for human-robot collaboration isdescribed. Then a description of an architecture that we havedeveloped is given that uses AR as a means for real timeunderstanding of the shared spatial scene. This architectureenables grounding and enhances situational awareness, thuslaying the necessary groundwork for natural and effectivehuman-robot collaboration.
