R2D2 in a softball: the portable satellite assistant

The Portable Satellite Assistant (PSA) is a softball-sized flying robot designed to operate autonomously onboard manned and unmanned spacecraft in pressurized micro-gravity environments. In this paper we provide an overview of some of the design challenges we face in making the PSA practical, effective, and usable for future space missions. In particular we highlight the need for an agent architecture supporting adjustable autonomy and a generic model of teamwork.
