Looked interesting........)

Quantified astronaut task performance will lead to enhanced training,
more
efficient crew operations, and optimized mission planning. In order to
systematically
address the relationships between the astronaut, tasks to be
accomplished,
and
environment, analytical models were developed in conjunction with
pressurized
space suit experiments and state of the art robotic technology. A joint
angle and torque
database was compiled for the Extravehicular Mobility Unit (EMU space
suit),
with
a novel measurement technique using both human test subjects and an
instrumented robot.
Using data collected in the experiment, a mathematical hysteresis
modeling
technique was
used to predict EMU joint torques from joint angular positions. The
hysteresis model was
then applied to extravehicular activity (EVA) operations by mapping out
the
reach and
work envelopes for the EMU. Suited astronaut range of motion limits and
locomotion were
also explored, yielding quantifiable results about the limitations
astronauts would face if the
current EMU, or an EMU-like suit, was used for a planetary exploration
mission.
