How does the soft robot's ability to move omnidirectionally and exert forces benefit medical applications?
-The soft robot's ability to move in all directions and exert precise forces makes it particularly interesting for medical fields like robotic surgery, where precision and adaptability are crucial.
What is the potential application of the soft robot in the medical field mentioned in the script?
-The soft robot has the potential to be used in minimally invasive surgical procedures, offering new possibilities for accessing hard-to-reach surgical targets.
How did the surgeon who tested the soft robot system react to its capabilities?
-The surgeon was pleased with the system, as it allowed them to view surgical targets from angles that would have been impossible with traditional instruments.
What does the future hold for the integration of soft and traditional robots according to the script?
-The future envisions a fusion of soft and traditional robots, where they cooperate rather than compete, potentially leading to more versatile and adaptable robotic systems.

Transcripts
if you think about a robot you usually
think about a complete humanoid made of
metal and this is very good if you want
to do repeated task while when you use a
soft robot you can deal with a more
uncertain environment and no object can
be touched without damaging them if you
look at a soft robots maybe you also
recognize an animal or biological
structure using soft materials to build
your robot is something that is
completely new so a completely
revolutionary framework should be
[Music]
developed the most paradigmatic probably
animal that could be uh an inspiration
for soft robots is the octopus because
the octopus completely lacks from any
kind of rigid part any bones from eyes
of a roboticist this is amaz because you
see a completely soft animal and you see
what he's able to do and you want to do
it as well so at the very beginning of
the project we were sure it would have
been very crazy I mean no Solutions were
aable at the time what we did was to
translate what we understood from the
arm into an artificial platform the idea
was was to replicate the main uh
features and bundle muscle that they
have and here you can see there are
three cables so that if one of them is
pulled what this obtain is a shortening
of the arm of course with a Carl if you
pull all the the cables together you
have only a shortening without any kind
of band The Octopus arm has been
designed to work in water so the best
way to see the performances of the arm
is to see it operating
underwater so the first time when we saw
the arm inside water we were Amazed by
the fact that the motion is so smooth
and the behavior of the Prototype that
is much closer to the Natural
counterpart in fact by putting an object
that is very close to the surface of the
arm it automatically adapt to the
position of the object this um ability
of motion omnidirectionally and of being
able to exert forces is also interesting
in the medical field in particular in
the robotic
surgery we share the inspiration with uh
the octopus project because we are
actually uh inspired by the octopus
tentacle we want to perform a minimal
invasive surgical procedure with that
har this is a part of the tentacle where
you can see all the functionality and
especially the the fact it's really
squeezable and
soft but if uh we take out the
hair then the section it's uh stiffer
and it cannot be easily deformed
anymore uh now we see a manipulator
which is made up of two segments which
can steer in all the direction and also
elongate this is a standard training box
for uh training Sergeant Sergeant tried
this uh this system and they actually
perform a surgical operation using uh
the view from the soft
robot I actually see
Sergeant really happy to have the
possibility to see uh some surgical
targets from uh that point of view
because with theid instruments they
couldn't reach certain points so maybe
one day it will be really employed in in
a surgical operation but there's still a
lot of challenge to be to be faced
before actually the what I see for the
future I very near is the fusion of soft
robots with traditional robots I don't
see a a challenge between them but a
cooperation we see a
robot let's say near everyone in the
future I would like to have a
robot uh I mean close to me
