Overview
abstract
Assembly and maintenance of the International Space Station (ISS) relies heavily on the use of extravehicular robotic systems. When fully assembled the ISS robotics complement will include three main manipulators, two small dexterous arms, and a mobile base and transporter system. The complexity and mobility of the systems and limited opportunities for direct viewing of the Space Station's exterior makes telerobotic operations an especially challenging task. Although fundamental manipulator design, control systems, and strategies for autonomous versus manual control vary greatly between the systems, commonality in the design of workstation controls and displays is considered essential to enhance operator performance and reduce the possibility of errors. Principal human factors opportunities are associated with workstation layout, human-computer interface considerations, adequacy of alignment cues for maintenance of safe approach corridors during mating tasks, spatial awareness challenges, integration of supplemental computer graphic displays to enhance operator global situational awareness, and training methodologies for preservation of critical skills during long-duration missions.
