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.
