Description

This paper discusses the requirements for robotics in future interstellar missions and describes the various robotic development activities at NASA KSC that are laying the basis for the robotics of the future. The first longduration interstellar missions, which might occur at the end of the 21 st century, would probably be preceded by trips to outer planets in the Solar System and by near-Solar interstellar probe missions. The time span, dangers, and uncertainties involved would almost certainly decree that the first missions be unmanned. If an interstellar mission involved a surface landing, all initial exploration would be performed by robots or other autonomous devices. These robots of the next century must possess true autonomy: onboard intelligence; sensor systems to provide information on the visual scene, temperature, radiation, task forces, and torques; stable locomotion; self-maintenance and repair capabilities; and so on. The varied sensor data must be integrated into an intelligent understanding of the environment to support decisions concerning that environment—for example, avoiding collisions or other dangers, or selecting areas of interest for exploration. The capability to store and transmit data, and to modify behavior based on experience, would also be required. Many of these capabilities are in their infancy today. However, NASA is expanding the state-of-the-art of robotics in directions which, while supporting near-term endeavors, will eventually lay the necessary foundation for the interstellar missions of the next century. For instance, the NASA KSC robotics program is making very meaningful contributions in areas of robot mobility, collision avoidance, vision systems, and special endeffectors. One example of this activity concerns the KSC Thermal Protection System robot, which provides an autonomous mobile platform and special end-effectors and vision systems for navigation, inspection, and positioning tasks. The robot can also store task data for downloading at a later date. Other developments at KSC include special mechanisms and controls for robotic space vehicle cleaning and component inspection, and the development of self-diagnostics for automated systems. In summary, while we are presently a long way from achieving the robotics capabilities to support interstellar missions, present-day robotics development activities at KSC and at other NASA centers are laying the groundwork for these exciting future endeavors.
