Collaborating in an intensive three-week lab in Yucatán, Mexico, modified how MIT junior Penelope Herrero-Marques views her function as an engineer.
The January journey was step one in a brand new partnership between MIT D-Lab and Perkins School for the Blind, a Massachusetts-based nationwide service supplier and worldwide nonprofit that strives to make schooling accessible to all youngsters.
As an undergraduate learning mechanical engineering at MIT, Herrero-Marques deeply linked together with her research, but at all times felt that one thing was lacking till she obtained concerned with D-Lab.
“I wanted the flexibility to consider social influence extra,” she says. “What I’ll bear in mind essentially the most from this journey was recognizing the worth and wonder of straightforward know-how.”
Herrero-Marques and 4 different college students joined Libby Hsu, affiliate director of teachers at MIT D-Lab, within the immersive expertise. Their aim was to collaborate with native companions to design individualized adaptive options to assist youngsters with a number of disabilities entry schooling.
Final 12 months in Mérida, Yucatán, Perkins opened its first worldwide workshop that builds adaptive gadgets and instruments. The group goals to launch related areas in extra areas.
“Our imaginative and prescient for the long run is to turn into a Mexican chief within the design and development of low-cost adaptive designs for college students with disabilities within the state of Yucatán,” says Ernesto Santana Palma, the workshop’s supervisor who welcomed the D-Lab group, designed, and iterated alongside them.
Listening earlier than co-designing
Based in 2002, D-Lab is open to all MIT college students and provides alternatives to co-design in collaboration with native companions to assist alleviate poverty-related challenges. Hsu defined that moderately than arriving in Mexico with a piece plan, the group spent their first week visiting native houses and colleges and fascinating with their “purchasers,” the kids, their caregivers, and educators, and attending to know the tradition of Yucatán, a state with one of many largest Indigenous populations in Mexico.
“We first needed to study cultural expectations, which supplies had been obtainable regionally, and listen to about Indigenous and different regional development strategies,” says Hsu.
College students had been overwhelmed by the apparent want, and impressed by how educators and caregivers invented makeshift hacks to assist the kids interact in each day actions like consuming, bathing, getting to highschool, or sitting as much as be taught.
Though future journeys will tackle different wants, the group in the end selected two to concentrate on for the remaining two weeks: They aimed so as to add foot and leg assist on current wheelchairs, they usually wished to supply caregivers a safer method to bathe youngsters with mobility points.
The adaptive bathtub prototype
“D-Lab does a very good job of not solely getting you concerned within the area, but in addition providing you with a format and methods to respectfully strategy tasks,” says Shruthi Shekar, a senior majoring in organic engineering.
She and her workforce heard from caregivers how bodily taxing and dangerously slippery it felt to wash youngsters with mobility challenges. They decided that an assistive bathing system might assist a toddler’s physique and assist immerse them safely within the water. They shortly landed on giant plastic bins for tubs — helpful for these with out entry to a tub or, in some instances, indoor plumbing. Nevertheless, discovering a porous, reasonably priced material to supply full-body assist to a toddler of any dimension posed a problem. It was a lightbulb second once they seen the sturdy, hand-knotted hammocks hanging in every residence.
“The hammocks apply even strain throughout your entire physique and supply quantity of assist,” says Shekar. “They’re snug, sturdy, and made regionally.”
In partnership with workshop volunteers who discovered the custom of hammock making from their grandmothers and custom-knotted a prototype to suit a toddler’s dimensions, Shekar’s workforce connected a hammock to a plastic tote utilizing sturdy knots.
The adaptive footrest attachment prototype
A prerequisite for the scholars’ journey was taking 11.025 (D-Lab: Development), an introductory course taught by Hsu every fall. Throughout one class session, they visited the workshop at Perkins Faculty for the Blind in close by Watertown, Massachusetts, the place they discovered how one can assemble a easy tailored chair from low-cost cardboard. The workshop has produced 1000’s of seats for youngsters world wide — serving to them to sit down up safely to eat, be taught, and work together.
Herrero-Marques assumed that cardboard could be a helpful materials in Mexico as effectively, however shortly found that the humid local weather makes the ply dissolve. Native lecturers defined that as a result of they lack footrest assist, youngsters in wheelchairs battle with leg cramps and slide precariously of their seats, presenting a choking hazard.
“The kids don’t have a lot mobility,” she says. “A typical 90-degree footrest could be painful for them.”
Cardboard was not an answer. The workforce iterated a number of designs for his or her adjustable footrest attachment earlier than aligning on a prototype constructed of sealed, light-weight wooden.
“Principally, there are two angles that you just’re in a position to alter — the angle on the knee after which on the ankle,” Herrero Marques explains. Every attachment is made to measure for its consumer.
Youngsters and their households in Yucatán are at present testing out the prototypes. This semester, D-Lab college students have continued to iterate the attachment design based mostly on their suggestions, and can return to Mexico in June to check out extra superior fashions.
“I’m by no means going to have a look at cardboard, hammocks, or plastic tubs the identical means,” Herrero-Marques says. “These are marvels of engineering. Not every part needs to be high-tech to make a big effect.”
