On the red carpet of film promotion, there is really such a "realistic Alita" who appeared with many Hollywood stars and big directors:

13 year old girl, Tilly Loki.

Tilly is not a star or one of the film's main creations, but she caught the audience's eye on the red carpet.

It's all because of her unusual arms.

When Tilly was only one year old, she unfortunately suffered from meningitis, which eventually led to sepsis.

Tilly's fingers were badly damaged by the disease, and eventually she lost her hands as a baby.

But mom and dad didn't give up and let Tilly live a happy life like ordinary people.

In the past few years, Tilly's parents have been looking for all kinds of "artificial limbs" for their daughters.

Tilly brought her first artificial leg when she was three years old. This prosthesis can be driven according to the signal of Tilly's upper arm skin.

But only allowing Tilly to move one finger at a time is not very flexible.

At the same time, it is very heavy, which makes Tilly feel very hard in the process of using it.

In the end, Tilly's parents decided to let her not wear artificial limbs for a while and learn to adapt to life without hands.

In the following years, although the technology has been improving, the cost of artificial limbs is still very expensive on the whole.

Sometimes, even if there are some newer technologies, it is impossible for the Tilly family to try them all regardless of economic factors.

Tilly can only try to adapt to her life without hands while waiting for a more advanced and cost-effective prosthesis.

Last year, when director Cameron started making Alita, he accidentally got to know Tilly.

After that, Cameron contacted Tilly's family and offered to buy Tilly a pair of artificial limbs with the latest technology.

As a result, Tilly has a pair of cool prostheses provided by a professional mechanical prosthetic technology company: HeroArms.

It was a gift from the great director and soon became a good helper to improve Tilly's life.

Compared with the traditional prosthesis, it has many remarkable advantages.

First of all, it is very light and flexible.

In terms of sensing and control, it is more sensitive than most traditional prostheses.

Highly specialized sensors can sense the tiny muscle contraction of Tilly's upper arm and convert it into electrical signals, triggering the corresponding actions of the manipulator.

Tilly can grab things through it like a real hand.

Secondly, this mechanical arm is cost-effective, about 5,000 pounds.

Many families can afford this prosthesis even without the support of a great director.

Other prostheses of similar materials and similar technologies cost between 30,000 and 60,000 pounds each.

Most importantly, the pair of mechanical arms did not try to help users "hide" the fact of disability, nor did they deliberately imitate the appearance of human arms like traditional prostheses.

On the contrary, people can see at a glance that these arms are mechanical, not real flesh and blood.

The reason why the appearance is opposite is that scientists have their own considerations when designing a mechanical arm with a sense of machinery, technology rather than reality.

They think it is not to make the appearance look "a bit like a real arm but a bit stiff", but to make people feel inexplicably uncomfortable.

It is better to show the characteristics of the mechanical arm directly, but it looks cute and cool.

In recent months, Tilly has become more and more accustomed to this mechanical arm and started wearing it to try something she didn't have a chance to try before:

For example, Tilly can finally eat with a knife and fork and eat fruit by herself.

You can tease cute kittens with snacks:

You can brush your teeth by yourself and finish some daily work that you used to need the help of your family:

Even, you can do something that not everyone can do.

For example, dance to your heart's content, stretch, rotate and jump, just like you have beautiful slender limbs:

For another example, sometimes Tilly will match himself with different styles according to the different appearance of each set of robotic arms.

What makes her most happy is that she can finally enjoy makeup like other girls and even become a beauty blogger!

Starting with the "head", Terry can comb her hair with a mechanical arm:

Can accurately use different brushes to smudge eye shadow;

Choose a different blush:

Accurately repair the volume of different areas of the face;

Of course, you can also apply different colors of lipstick yourself:

At the same time, Tilly and her friends at school are more curious and enthusiastic about Tilly because of the cool mechanical arm.

Everyone wants a chance to shake hands with Tilly's mechanical arm.

Now Tilly is full of expectations for the future:

I can be an actor, a singer, a dancer and a bionic man.

I feel that every obstacle that once existed in front of me is slowly being broken! "

Tilly's story not only makes people happy about her change, but also makes people admire the scientists behind her.

Perhaps, in real life, the scientists who have been studying hard behind Tilly's manipulator are the real "fighting angels".

I hope more people in need can feel the hope and courage of life again from such scientific and technological achievements!
