&lt;p&gt;The HET2 Astrobee Element will focus on developing a new free-flying robot suitable for performing IVA work on the International Space Station (ISS). The new robot will build upon technology and lessons learned from the Smart Synchronized Position Hold, Engage, Reorient, Experimental Satellite (SPHERES) robot, which was developed and tested by the Human Exploration Telerobotics (HET) project under the Technology Demonstration Missions (TDM) program. Astrobee will be designed to address a variety of use cases, which will be developed and detailed in collaboration with the Advanced Exploration Systems (AES) program and the ISS SPHERES Facility in the Human Exploration and Operations Mission Directorate (HEOMD). Candidate use cases include a remotely operated mobile sensor platoform for IVA surveys (camera views, sound level surveys, etc.), automated logistics (e.g., mobile inventory with a RFID reader), and free-flying robotic test bed in micro-gravity.&lt;/p&gt;&lt;p&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;At the highest level, the Astrobee&amp;nbsp;system includes the free-flying robot itself, a dock/resupply station for replenishing power, and any necessary hardware and software for communication, control and data transfer.&lt;/p&gt;&lt;p&gt;Astrobee will be self-contained and autonomous. Ideally it will be capable of fully autonomous localization and navigation inside the United States Operating Segment (USOS) of the International Space Station. Astrobee will have video cameras on board that will allow it to serve as a remotely operated mobile camera platform, and may be used for localization and navigation.&lt;/p&gt;&lt;p&gt;Astrobee will also have an expansion ports where additional sensors and/or hardware can be attached for demonstration, testing and use aboard the station. Additional sensors that may be attached to or integrated with the Astrobee include a RFID reader and the necessary software to communicate with the inventory management system, a HD camera, and a sound level meter.&lt;/p&gt;&lt;p&gt;Astrobee will communicate principally via the station LAN. The propulsion is likely to be electric-motor-driven fans. Localization may include vision-based navigation with and without fiducials, IR beacon localization, and Wi-Fi localization. The Astrobee will also include a perching arm to grab ISS handrails; this will allow the Astrobee to hold position without using its propulsion system.&lt;/p&gt;
