Keywords

💡Soft Robot

A soft robot refers to a type of robot constructed from flexible materials, allowing it to adapt to various environments and interact with objects without causing damage. In the context of the video, soft robots are contrasted with traditional rigid robots, highlighting their suitability for uncertain environments and delicate tasks. The video script mentions that soft robots can deal with environments where objects can be touched without being damaged, showcasing their unique advantage over traditional robots.

💡Uncertain Environment

An uncertain environment is one where conditions are unpredictable or not well-defined, requiring adaptability and flexibility. The video emphasizes the importance of soft robots in such environments, where their ability to conform and adapt to changing conditions is crucial. This is exemplified by the script's discussion of how soft robots can handle tasks in environments where traditional rigid robots might fail due to their lack of flexibility.

💡Biological Inspiration

Biological inspiration refers to the process of drawing ideas and designs from nature to solve human problems or create new technologies. The video script highlights the octopus as a prime example of biological inspiration for soft robots, noting the octopus's lack of rigid parts and its remarkable abilities, which roboticists aim to replicate in artificial systems.

💡Octopus

The octopus is a marine animal known for its flexibility and intelligence. In the video, it serves as a model for soft robot design due to its completely soft body and ability to perform complex tasks without any rigid structures. The script describes how the octopus's arm movement and adaptability are being mimicked in soft robotic prototypes.

💡Muscle Bundles

Muscle bundles are groups of muscle fibers that work together to produce movement. In the context of the video, the design of soft robots is inspired by the muscle bundles found in octopus arms, which allow for controlled movement and force exertion. The script mentions replicating these features in the soft robot's design to achieve a similar level of dexterity and control.

💡Cables

In the video, cables are used in the soft robot's design to mimic the function of muscle bundles in an octopus's arm. By pulling on these cables, the robot's arm can shorten, similar to how an octopus controls its movement. The script describes a system with three cables that, when pulled, cause the arm to contract, demonstrating a key aspect of the soft robot's functionality.

💡Underwater Operation

The video script describes testing the soft robot's arm underwater to observe its performance, as the octopus arm it mimics is designed to work in water. The smooth motion and natural behavior of the prototype underwater are highlighted, showing how the soft robot's design allows it to operate effectively in an environment similar to that of its biological inspiration.

💡Omnidirectional Motion

Omnidirectional motion refers to the ability to move in any direction, which is a key feature of the soft robot's arm as described in the video. This capability is important for applications like robotic surgery, where the ability to move in multiple directions can provide greater access and precision. The script illustrates this by showing how the soft robot's arm can adapt to the position of an object placed near its surface.

💡Medical Field

The medical field is highlighted in the video as a potential application area for soft robots, particularly in robotic surgery. The script discusses how the soft, flexible nature of the robots could be used to perform minimally invasive surgical procedures, providing advantages over traditional surgical instruments in terms of accessibility and precision.

💡Manipulator

A manipulator is a mechanical device used to grasp, move, or manipulate objects. In the video, the soft robot's arm is described as a manipulator with multiple segments that can steer in all directions and elongate. This feature is showcased in a training scenario where a surgeon uses the soft robot to perform a surgical operation, demonstrating its potential in the medical field.

💡Fusion of Soft and Traditional Robots

The concept of fusing soft robots with traditional robots is discussed towards the end of the video script. This fusion is seen as a future development where the two types of robots can cooperate, combining the strengths of traditional robots with the flexibility and adaptability of soft robots.

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
