Abstract

In a two-year study of a collaborative human-robot system, researchers observed a science team in Pittsburgh and a robot in Chile.The system was part of a project intended to inform planetary exploration while studying a terrestrial desert. Over two years, autonomyincreased such that the robot could execute sequences of commands and, under certain circumstances, make autonomous decisions aboutinstrument deployment and data collection. Analysis of the observational and project artifact data addressed the impact of increasinglevels of autonomy on how users reach common ground with a remote robot in terms of an accurate, shared understanding of the robot'scontext, planning, and actions. Findings suggest that as autonomy increases, users' inability to understand the reasons for the robot'sactions disrupts the creation of common ground. The authors describe the implications of this work for human-robot system design.This article is part of a special issue on Interacting with Autonomy.
