The Intelligent Robotics Group (IRG) is a research organization within the Intelligent Systems Division at the NASA Ames Research Center, located in California's Silicon Valley. The group conducts applied research in robotics and autonomy, serving as one of NASA's principal organizations for robotics expertise alongside groups at the Jet Propulsion Laboratory and Johnson Space Center. Its portfolio spans robotics for human exploration, perception and navigation, user interfaces, software architectures, and simulation.
IRG has developed notable spaceflight systems, including the Astrobee free-flying robots deployed on the International Space Station, and was a primary contributor to the VIPER lunar rover in flight software, navigation, simulation, and mission operations. The group has also conducted numerous robotic field test campaigns to support spaceflight mission concept development, and its work led to the commercialization of the GigaPan system in collaboration with Carnegie Mellon University.
Research Areas
The group's research activities emphasize applied robotics for space exploration. Key areas include perception and navigation, where algorithms enable rovers and free-flying robots to map environments and traverse terrain autonomously. User interface development focuses on tools for operators to supervise robots in remote or hazardous settings, often incorporating simulation environments for mission planning and training. Software architectures developed by IRG support modular, reusable systems for robotic control and data processing.
Astrobee Free-Flying Robots
Astrobee is a series of cube-shaped robots designed to operate inside the International Space Station. IRG developed the Astrobee system, which assists astronauts with routine tasks, such as inventory tracking and environmental monitoring, and serves as a platform for experiments in microgravity robotics. The robots use electric fans for propulsion and cameras for navigation, enabling autonomous docking and recharging. Astrobee builds on earlier free-flyer concepts and has been operational on the station since its deployment in 2019.
VIPER Lunar Rover Contribution
IRG was a primary contributor to the VIPER (Volatiles Investigating Polar Exploration Rover) mission, which aimed to map water ice at the lunar south pole. The group provided flight software, navigation algorithms, simulation tools, and mission operations support. VIPER's design included a mobile robot with a drill and spectrometers, and IRG's navigation systems were intended to enable autonomous traversal of challenging polar terrain. The mission was scheduled for launch in 2024, though as of 2025 its status has been subject to programmatic reviews.
Field Testing and GigaPan
IRG has organized and participated in many field test campaigns at terrestrial analogue sites, such as deserts and volcanic regions, to validate robotic systems under Mars-like conditions. These tests informed the development of mission concepts for human-robot teams and sample return scenarios. The GigaPan system, developed with Carnegie Mellon University, allows the creation of high-resolution panoramic images by stitching together thousands of photographs. Originally used for planetary surface documentation, GigaPan was commercialized for public use, enabling educators and researchers to share immersive imagery.
Collaboration and Impact
The group collaborates with academic institutions, including Carnegie Mellon University, and other NASA centers. Its work has influenced robotic software practices and contributed to the broader field of artificial intelligence in space applications. IRG's experience with the Mars Exploration Rover mission, documented in a 2004 technical report by Kristen Stubbs and Illah Nourbakhsh, highlighted lessons in mission operations and human-robot interaction. The group's contributions to machine learning and computer vision are applied in navigation and perception systems, though specific details of these algorithms are not publicly detailed.
