Description
Recent design activities for the International Space Station have included studies of the operations and productivity of the U.S. Laboratory module. A major finding was that the most 1 imi ted resource on the Station will be crew time. A ground-controlled robot has been proposed by Teledyne Brown Engineering that will help alleviate these constraints and allow around-the-clock U.S. Laboratory operations. However, the ground contra l of a mechanism in Earth orbit imposes command and feedback delays because of the distance and communicat i ans network involved. A unique predictive display for use by the ground operator in the presence of varying time delays has been developed and tested and has reduced the 11 move-and-wait 11 task times normally associated with delayed feedback teleoperations, minimized operator training, and reduced downlink bandwidth required.
