[robotics-worldwide] Survey to help define soft robotic metrics [news]
To those interested in soft robot design, modeling, and control:
More and more researchers are looking to introduce robots into unmodeled
areas or areas where the robots will be working with or around humans or
delicate equipment. Traditional robotic systems have rigid links and
actuators which can be dangerous in these environments. Many in the
robotics community have started exploring the field of soft robotics which
uses naturally compliant materials in the structure and/or actuation of the
robots as a method to address these issues.
However, soft robots were developed with different goals in mind than
traditional robots meaning that the traditional metrics used to evaluate
standard robots are not necessarily effective in evaluating these robots.
As far as we can observe there are no established metrics that define good
soft robot performance.
To help define valid soft robot metrics we have developed a questionnaire
to query the robotics community on what they think are good metrics for
soft robotics manipulators. The survey involves rating different
metrics/measurements on their importance when evaluating the performance of
robots during five different types of tasks. These metrics/measurements do
not always inherently denote good or bad performance but can be used to
define desired performance for these and additional tasks. The
metrics/measurements can then be used in for the design and evaluation of
soft robot hardware as well as tuning soft robot controllers. Furthermore,
the metrics can be used to determine what type of robot (rigid or soft)
should be used for specific tasks.
