Handled: UNLV Student Develops Robohand for World Series

When Big league Baseball fans are asked to imagine the individual on the pitcher’s mound at game four of the World Series, a 7-year-old woman probably does not enter your mind.

But that will be the case Saturday when young Hailey Dawson of Las Vegas tosses out the opening pitch in the face-off in between the Los Angeles Dodgers and Houston Astros.

Although Hailey’s pitch is just ritualistic, there’s absolutely nothing trivial about how she got there. Her fastball is powered by a robohand, custom-made by another inspirational girl, Maria Gerardi.

The blue and gold 3D-printed flexihand is the eighth– and soon-to-be most well-known– that Gerardi, a UNLV engineering graduate student, has actually developed and constructed for Hailey.

” Seeing Hailey out there– she’s simply a little woman doing her thing and having a good time– shows to anybody that there are no excuses; anything really is possible,” said Gerardi, reviewing Hailey’s journey to Major League Baseball. “Understanding I was able to play a part in that, I’m so humbled. It’s that a-ha factor; this is what I want to make with my life.”

Due to an uncommon condition called Poland Syndrome, Hailey was born without a right pectoral muscle; her right-hand man is missing three fingers and her thumb and pinky likewise are undeveloped.

3 years back, Hailey’s mom teamed up with UNLV College of Engineering trainees and professors to style and build a 3D-printed prosthetic hand from scratch. Hailey, a big fan of baseball, went on to deliver opening pitches for the Baltimore Orioles and the Washington Nationals. Now– in addition to throwing out the very first pitch in the Oct. 28 World Series video game– she has invitations to pitch next year by all other Big league Baseball teams.

The first numerous robohands, which were constructed using existing online designs as a guide, were vulnerable to breaking easily. Gerardi, who is slated to graduate with a master’s degree biomedical engineering in spring 2018, came on board a couple of months into the project, after the very first convenient model was constructed.

The Right Place Gerardi’s own journey on the job began in a high school classroom, where she fell in love with biology her senior year. However it’s possible it was constantly in her genes: “On my mother’s side of the family, everybody’s an engineer– all the men– and my Grandfather would make jokes that he desires a ‘lady engineer.’ So he was overjoyed when i said I was going to get my master’s in engineering.”

The Michigan native completed her undergraduate biology degree at Wayne State University in Detroit, then took a couple years off and operated at a call center while debating medical or oral school.

One day, an older associate encouraged her to move and explore while she’s young. With relatives already in Las Vegas, she made the relocation 5 years earlier and was so enamored with the city that she chose to remain and enlist in UNLV’s College of Engineering.

When she spotted a flyer looking for students to assist with Hailey’s hand job, she understood she remained in the best place.

” It captured my eye mainly because I love kids,” she said. “They said they wanted to help [Hailey] do activities that everybody else can do. Growing up, I keep in mind playing baseball, like Hailey wants to do.”

Gerardi, who ‘d formerly been unsure of her specific path in engineering, was hooked after fulfilling Hailey. “Enjoying her use the hand for the very first time, if I had any doubts about exactly what I wanted to do, this made me recognize ‘This is it’,” she said. “The look on her face and how delighted her moms and dads were, it was a for sure ‘A-ha!'”

Building the Hand A typical day in the laboratory includes Gerardi utilizing computer software application to make continuous adjustments to the robohand as Hailey grows. Gerardi has likewise created an original style for another local child whose partially formed hand forms a larger fist than existing models can accommodate.

Each robohand takes a minimum of a week to make. The process needs a mix of biology and kinesiology know-how (to comprehend how the body and muscles involved in various comprehending movements work), along with mathematics (to compute part dimensions and develop 3D designs) and engineering (to create elements that are small yet thick adequate to not break).

The hand uses no electronic devices. Rather, when Hailey bends her wrist, the fingers move in or from a grasping shape.

Hailey began three years back at 60 percent of a full-sized (One Hundred Percent) model, and is now at 83 percent. Gerardi has made eight hands for her so far, consisting of two– an initial and a nearly-identical backup– for the World Series. Hailey likely will require a new hand each year as she grows. Each hand costs about $200 in materials, and Hailey’s mother, Yong, brings a toolbox to adjust stress screws or reattach fingers to joints on the fly.

Gerardi’s design– called M1, for her given name– can be gotten used to fit anyone without a fully-formed hand by taking an image of the user’s hand, determining measurements, and digitizing them through the computer system software.

In the meantime, the hand is for general usage (holding bags, occasional writing, and so on) and Hailey hasn’t been choosy about design– generally they are hand painted with a style such patriotic colors or as a team logo for opening pitches. For Hailey’s check out to the White House, Maria even used stick-on nail polish. Her main demand? A gauntlet, or arm covering which attaches the hand to her wrist, that offers sufficient area to get autographs from her favorite Major League Baseball players.

But the engineering team of undergraduate and college students that Gerardi leads continues looking into methods to improve the style in case Hailey wants hands for specific purposes, such as composing or other tasks/sports as she ages.

Future Plans At first, Gerardi and another graduate student, Jordan Harris, worked to move the thumb since Hailey could not get larger items effectively and obstructed when pitching. In the in 2015, Gerardi has added an adjustable thumb and fingertip ridges so Hailey can acquire a better grip on items.

Building on Harris’s exploration of an approach to enhance individual finger mastery and grip without making use of electronic devices, Gerardi is writing her thesis on her quest to construct a universal hand that has an adjustable thumb which other online designs do not have.

However Gerardi, who is also in the middle of planning for her wedding in two weeks, has been working feverishly to design, put together, and hand paint Hailey’s unique World Series model.

” I was expected to protect my thesis however I put it off due to the fact that this is a little bit much better,” she said, chuckling. Gerardi stated she’s not an emotional person, but “watching Hailey with the hand, writing and tossing, simply to see the effect of it and having the ability to watch Hailey grow with the project, it just got me. It’s a great sensation to understand my 3 years of hard work have actually led here. Not everybody can state their work has actually been broadcast to millions.”

In truth, Gerardi’s dream after graduation is to create a non-profit that will permit her to help other children like Hailey.

” Exactly what I have actually found out here at UNLV is that anything is possible truly,” stated Gerardi, adding that her 85-year-old grandpa has her bring her latest M1 model each time she goes to house. “He’s really proud he got his lady engineer.”
