Jaelyn Crebbin is a regular kid.

The 11-year-old Oak Harbor girl plays the baritone, competes in soccer and draws animals.

She loves purple and sometimes her sister bugs her.

Jaelyn also was born missing a left forearm and hand.

While that’s never stopped Jaelyn, a gift from some Oak Harbor High School students is helping her feel more like other kids.

The Wildcat robotics team created a robotic arm for her.

Jaelyn loves it.

She can bounce a ball, hold a water bottle and give a high five — with either hand. And it’s purple, her signature color.

“At first it was a little scary,” she said. “I was a little shy to work with the Robotics Club.”

The students used a design from a nonprofit that provides designs of prosthetic hands to volunteers with the know-how and equipment to create them.

Unlike traditional prostheses which can cost thousands of dollars, these devices can be made with about $30 in materials and a 3D printer.

A research scientist at Rochester Institute of Technology started the nonprofit, e-NABLE, in 2013. Its network of volunteers numbers in the thousands and has provided hands in 37 countries.

They aren’t meant to take the place of a fully-functional device. The nonprofit is trying to help people who can’t afford a traditional prosthesis and children who simply grow too fast to make one feasible.

Children use the prosthetic hands for simple tasks. Jaelyn’s arm has fingers that open and close when she bends her elbow. Having two hands makes it easier to balance and do things like ride a bike, swing, catch a ball and swim.

The robotics team first heard about the nonprofit a few years ago and applied for a grant to purchase the $2,000 3-D printer, said Che Edoga, robotics teacher and student mentor. Last spring the students measured Jaelyn and set to work creating the arm. It took a little longer after the printer broke. She had her final fitting a few weeks ago.

“It’s starting to dawn on them they did something really cool,” Edoga said. “Having made that hand, they can see how it’s changed this person’s life.”

The team is working on other projects, including a tricycle that can purify water, a giant drone that could be used for search and rescue and a robot decoy deer that could help catch poachers.

The students aren’t done helping Jaelyn. They are designing another hand that will open and close with skin sensors that respond to a twitch of her muscles.

The students also plan to amp up the cool factor by adding a light — you know, for the Iron Man laser effect.

“I want my kids to know engineering is about solving problems and they can get on their computer and solve them right now,” Edoga said.

Jaelyn started sixth grade at Coupeville Middle School earlier this month, the same school her mom, Toni Crebbin, teaches math.

“I saw her at school and it wasn’t this shy little girl,” said her mom. “She just had a big grin on her face.”

Mike Crebbin, a teacher at Oak Harbor High School, said his daughter has always been independent and capable. When they adopted her from China at age 2, she could already dress herself and use chopsticks.

“She could really do anything she wanted,” he said.

The difference is in other people’s perceptions of Jaelyn: how the arm has changed that first look.

Other children gawked or touched Jaelyn’s arm. Adults asked insensitive questions. Fed up with the ogling, she would sometimes stuff her arms into the pockets of her sweatshirt.

“She’s not afraid of it, but people gave her pity and she never asked for that,” said her father.

“Now it’s ‘Look isn’t that neat,’ instead of, ‘Oh, that’s sad.’”

For Jaelyn, that’s made all the difference.
