The Astrobee robots began operations on the International Space Station (ISS) in April of 2019. These 32-cm-wide, 9-kg, cube-shaped free flyers are capable of autonomously traversing the US Orbital Segment of ISS and performing tasks to assist astronauts in their day-to-day activities. The Astrobee Facility also provides an on-orbit testbed for guest scientists desiring to try new technologies in zero-g. This presentation will provide an overview of the Astrobee system and some of its key enabling technologies, including propulsion, navigation, and human interfaces. Additional information and publications can be found on the Astrobee website:
