user interaction during lifting and
placement.
Although designed particularly to aid
in NASA's SLS threaded load line assembly,
the extra compliance provided by the
Soft Mate system may also benefit other
applications where additional control
and precision are required for placing or
mating heavy components. The design
has undergone extensive stress analysis
and is based on commercially available
components that can be scaled and optimized
for different weight requirements.
The system provides the flexibility needed
to assemble heavy components with
threaded connections or other precision
crane placement applications where
greater compliance is needed.

Coiled
Linear
Actuators for
Soft Robotics
This artificial muscle
technology enables more
human-like motion.
Northern Arizona University,
Flagstaff
In the field of robotics, researchers are
continually looking for the fastest,
strongest, most efficient, and lowest-cost
ways to actuate robots to make the movements
needed to carry out their intended
functions.
The quest for new and better actuation
technologies and " soft " robotics is
often based on principles of biomimetics,
in which machine components are
designed to mimic the movement of
human muscles and ideally, to outperform
them. Despite the performance of
actuators like electric motors and
hydraulic pistons, their rigid form limits
how they can be deployed. As robots
transition to more biological forms and
as people ask for more biomimetic prostheses,
actuators need to evolve.
Researchers have developed high-performance
artificial muscle technology
that enables more human-like motion
due to its flexibility and adaptability.
They call the actuators " cavatappi " artificial
muscles, based on their resemblance
to cavatappi pasta.
Because of their coiled (helical) structure,
the actuators can generate more
power, making them an ideal technology
for bioengineering and robotics applications.
In the team's initial work, they
demonstrated that cavatappi artificial
muscles exhibit specific work and power
metrics ten and five times higher than
