Baby on board – and at the joystick

first_imgNEWARK, Del. – With a 6-month-old at the controls, researchers at the University of Delaware are encouraging underage driving. Their ultimate goal is to help immobile, disabled children move and explore. The researchers are using robotics in an odd contraption that’s sort of a cross between a bumper car and a robot. In a recent test, Aniya Harris, a normally developing 6-month-old, scooted across the floor in delight by pushing a joystick on the little vehicle. She’s too young to steer it. “I think she thinks, `Joystick means go.’ I’ll take that right now,” said Cole Galloway, a physical-therapy professor who heads the infant motor behavior lab.

Wheeled robots could enable them to move and explore the world around them, which studies suggest is critical to their development. Researchers in the United Kingdom have been working for years on powered mobility for toddlers. However, Galloway said, conventional wisdom has held that because of safety issues, children aren’t considered ready for that until age 4 or 5; the earliest age doctors might recommend powered mobility is age 3. That means too many children are at risk of losing out on the important early link between mobility and their overall development, Galloway said. “As soon as you’re reaching, as soon as you’re walking, your cognition explodes,” he explained. Sunil Agrawal, a professor of mechanical engineering at the university, has been working for years on wheeled robots with infrared and sonar sensors that can avoid obstacles. A prototype based on those models is being used in studies involving about a dozen typically developing infants and a smaller number who have special needs. Using a computer and wireless technology, researchers can measure the frequency and duration of joystick use by a child; the location, speed, and distance traveled by the vehicle; and the amount of time spent “driving.” During a recent visit, Aniya sat in UD1’s blue plastic seat and tugged on the joystick as her aunt, Daina Montgomery, beckoned from a few feet away with a toy. The little girl whirred across the floor to her aunt. While Aniya has no disabilities, her aunt believes the mobility experiment has helped her move rapidly from an early stage crawl to being able to climb stairs and pull herself up. Galloway and Agrawal said their research is still early, and parents shouldn’t expect to see robotic vehicles on the market anytime soon. They hope to get funding to continue their research and develop a second-generation robot. A few similar products are already commercially available in England, including the “Wizzybug.” It was developed by researchers at the Bath Institute of Medical Engineering for disabled 2- to 5-year-olds. While it doesn’t have some of the robotic features of UD1, the Wizzybug has both a programmable joystick and parental control. Ruth Everard of Dragonmobility Ltd. in Cambridge, England, another producer of powered vehicles, said the research at UD should add to the existing body of knowledge about mobility and the developmental needs of children. “I think it’s really important that people combine their knowledge and look at what’s been done before,” she said. Everard, who suffers from spinal muscular atrophy, was 21 months old when her father designed a powered chair for her, spawning a company that has provided mobility for children as young as 11 months old. 160Want local news?Sign up for the Localist and stay informed Something went wrong.
