This mother’s day, we bring you the story of one woman’s dream to give her child mobility. This ScienCentral News video reports on research that is opening the door for special needs babies to explore the world- with the help of robots.

and Terri Peffley, Andrew’s mother

When Terri Peffley was 19 weeks pregnant with her fourth child, Andrew, she went in for a routine ultrasound hoping to find out whether it was a girl or boy and found out that he has a neural tube defect called spina bifida. Peffley, a pediatric occupational therapist, had a lot of experience with special needs children. After the initial shock, her training kicked in and she started planning.

“Once he was born I knew I wanted to get him up and moving just like the other kids his age would be, and I knew that it was going to take twice as long and [be] twice as hard, she recalls. “I felt this sort of time crunch or just fighting the clock. “

Peffley explains that because Andrew had very limited mobility in his legs, he was dependent on others to move him around. Special needs children do not usually get power mobility until they are three to five years old. She worried that Andrew’s self-esteem would be affected.

"I really didn’t want him to be on the sidelines. I wanted him to live life and be in the mix and do everything else that the other kids were doing as much as possible,” she says.

Peffley did not know that the answer was about thirty minutes away at University of Delaware. It was only recently that pediatric researcher Cole Galloway and robotics engineer Sunil Agrawal had started working together. Galloway had worked for years with both typically developing and special needs children, but robots were never part of the picture. Agrawal had worked in robotics for almost 25 years and in the last seven years had started using robotics for rehabilitation of adults— but he had never worked with babies. He was working on a project with small robots that communicate with each other when he approached Cole with the idea of helping babies. Galloway was intrigued by the possibilities.

“I told Sunil, ‘You know if, if, if’—and it’s a big if— ‘if these babies will drive this robot, we might have the first power chair for young babies,’” recalls Galloway.

They teamed up to create the first infant-sized robotic wheelchairs and started testing them with normally developing infants. They found that children as young as six months old could learn to use the joystick that controls the chair. The robotic chairs are equipped with cameras that record the baby’s face and hands. They also monitor everywhere the baby goes and if there is contact with an obstacle. For safety, there is a separate joystick so that an adult can take over the controls.

Andrew’s physical therapist, Tracy Stoner, also of University of Delaware, told Peffley about the research. Peffley contacted the researchers and Andrew became the first special needs baby to try out the robots. Although he was just seven months old, he caught on quickly and learned how to navigate. When Andrew outgrew the infant chairs, the researchers did not want him to be left without mobility. So they modified an adult power chair for Andrew.

So why don’t special needs kids get power mobility earlier?

“The big barrier is safety,” explains Galloway. “If you train a young infant to be able to drive around, what keeps the infant out of harms way? What keeps the infant from running into the coffee table, driving down the stairs, driving into the road?”

Galloway and Agrawal are working on a solution to that in the next phase of their research. They are testing newer robotic wheelchairs with sonar sensors on the front and back to keep the infant from bumping into obstacles or leaving a certain area. The next step is to test them in private homes. Their goal is to make a commercially available robotic motor chair for special needs infants to use indoors and outdoors.

“Every year we wait around is another year that kids sit for days and weeks and months, and we have a lot of work to do,” says Galloway.

Meanwhile, Andrew continues to get intensive physical therapy and is expected to walk one day. Terri Peffley says that her expectations for him are the same as for her other children.

“That he is happy and he’s successful in what he wants to do, that he makes a difference in this world,” she says.

    What a terrific story of hope. I didn’t realize how, as able bodied people, we take movement for granted. Exploration of one’s environment is crucial to the developing mind. I wish the story was longer just to learn more. Please report back to us on how Andrew is doing! I love the voice of the narrator!

    I don’t work with Andrew but work at the site in which Andrew operates the robot and he is amazing! All the dedication, collaboration, and caring that is given to this project opens up many opportunities for children with special needs. Keep up the good work Andrew! It was a great video-Kudos to all…..

    I think this is such a wonderful program, and it’s so amazing that this project will be able to help so many children, it’s inspirational! Keep up the good work and congrats on your success! (By the way, Gage really loves driving the chair, he told me to tell you any other time you need him as a crash test baby, he’s up for it! ;] Good luck!)

    Estimado (a)

    Muy interesante!!!. Tengo un hijo con Espina Bifida y plegia de piernas (Lesión medular L1L2). Vivo en Chile, específicamente en la ciudad de Arica. Esta tecnología aún no se encuentra en los mercados de latinoamérica. Quisiera saber el costo de la silla y si existe la posibilidad de enviarla a Chile.

    Favor responder.

    Atentamente, Carlos Barboza. Arica, Chile.

    Thanks for sharing this interesting article and video. Hope there will be many more robotics chair for children with special needs for indoor and outdoor mobility.

    Having worked with special ed students as a paraprofessional in the school system , I understand the need for this type of chair. The mobilization of children
    earlier ,at the age when they would normally be walking is very important for special needs children. Especially when they have sibllings with no disabilities.

    An addiction to sports gambling is rather similar to any other kind of addiction as the addiction begins to take
    charge and control your life. This is a competitive advantage for sports betting businesses because the
    options that it gives are more than what anybody expects.

    of time and you get it.

    like to see explored, please let me know.
