This paper describes continuing research supporting the Morphing Upper Torso
spacesuit design, which uses robotic augmentation of a rear-entry pressure suit to adjust
torso dimensions. This concept has the potential to provide easier ingress/egress of the suit,
increased mobility when pressurized, and reduced astronaut workload during
extravehicular operations. In previous work, the forward and inverse kinematics for the
system have been solved, two static models have been built, and data from a range-of-motion
(ROM) study has been collected using a Vicon motion capture system. During the ROM
study, test subjects wore simulated shoulder scye bearings as they performed selected tasks,
with the intent to measure human motion in relation to scye bearing motion. The research
presented in this paper describes the data analysis and results of the ROM study. This
