Meet the Ottawa boy who\'s about to get a new hand (with video)

Sebastian Chavaria, who had to fight for his early survival, had repeatedly undergone surgery to expand the airway, and finally had a tracheal incision --
He has a hole in his throat.
But now, when he was six, he faced another problem.
He needs a fake hand.
The help this time came not from CHEO surgeons but from an innovative engineering lab at the University of Ottawa and a unique competition.
Challenge: design a new fake hand for Sebastian and make it using a 3D printer in the lab.
Sebastian was born with a left hand that never grew to its full size.
Their mother, Letti Chavaria, said he and his brother were \"happy and active boys \".
The problem is that traditional fake hands are expensive: a hand that he will soon grow up costs $25,000 or more.
The doctor says he should be installed from now on when he stops growing.
But as a mother, LeTV cannot accept this.
Just then, she heard of a network called \"Creating the Future\" where volunteers used 3D printers to make robots for children.
Sebastian became the first Canadian child to receive a child in last September.
The hands look a little bright.
Colorful plastic toys, but they can grab things and open and close your fingers with the action of your wrist.
But as Sebastian grows, he will soon need a new hand.
This makes Lettie think: It will also help other Canadian children if the use of printers is widespread.
This brought her to Hanan Anis, who teaches engineering at the University of Ottawa.
Anis is involved in a U of O lab called Makerspace that sees itself as a place for designers and inventors to try out new ideas.
It has a lot of engineering students but is also open to the community on Sunday.
It can shape plastic and wood, and it can also make control devices for machines. (
An example: Anis is developing a system for a person with a stroke to control the keyboard by breathing, \"so at least they can talk to the world and say what they\'re thinking. ”)
\"There are many prototypes for start-up companies --
\"Industrial design,\" she said.
Now, designing and building a hand is a \"challenge\" for Sebastian \".
She recalled her first meeting with Letti Chavaria.
\"She cried, I cried,\" said the professor . \".
And then they started working.
She asked for help from another engineering professor who handled the prosthesis, who opened the door to the challenge.
They also brought Sebastian in so that the students could see his hand and find out the right questions.
\"It\'s one thing to adopt an open design (i. e.
Free open source)and tweak it. . . .
\"What we are asking for is a new design,\" she said . \".
Anis has opened up the challenge.
Give us an idea, she said, and we\'ll test it out.
The winner received $1,000.
Of the 73 participants, 3 entered the finished product phase.
Sebastian is testing three finalists this week.
\"Friday is a big day.
\"Sebastian will announce the winner,\" she said . \".
But the story is not over yet.
Letti Chavaria believes that no matter which hand wins the challenge, there will be more development in the future.
For example, she wants to have a design where the fingers can be locked in place so that Sebastian and the other kids can hold onto the handle of the bike firmly.
