Armenian scientist designs drones to help old people
The ranks of older and frail adults are growing rapidly in the developed world, raising alarms about how society is going to help them take care of themselves in their own homes.
Naira Hovakimyan has an idea: drones, The New York Times reports.
The University of Illinois roboticist recently received a $1.5 million grant from the National Science Foundation to explore the idea of designing small autonomous drones to perform simple household chores, like retrieving a bottle of medicine from another room. Dr. Hovakimyan acknowledged that the idea might seem off-putting to many, but she believes that drones will not only be safe, but will become an everyday fixture in elder care within a decade or two.
“I’m convinced that within 20 years drones will be today’s cellphones,” she said.
Her research is just one example of many approaches being studied to use technology to help aging people.
Even though fully functioning robot caregivers may be a long way off, roboticists and physicians predict that a new wave of advances in computerized, robotic and Internet-connected technologies will be available in coming years to help older adults stay at home longer.
“Loneliness is at epidemic levels among elders in the U.S. today,” said Juliet Holt Klinger, senior director of dementia care and programs at Brookdale Senior Living, one of the nation’s largest providers of assisted living and home care.
Brookdale is using a variety of Internet-connected services to help aging clients stay more closely connected with family and friends. Ms. Holt Klinger said there was growing evidence that staying connected, even electronically, offsets the cognitive decline associated with aging. “We have story after story of reconnection with families through Skype,” she added.
For all the promising ideas, however, skeptics also note that many ideas are “technologies looking for a solution” that inevitably fail the test of practicality.
“We all get really excited on the upside, and then we go through this trough of disillusionment,” said Laurie Orlov, a business analyst who began the Aging in Place Technology Watch blog in 2008.
Even so, examples of robotic and artificial-intelligence-derived technologies that will be commercially available in the next decade include intelligent walkers, smart pendants that track falls and “wandering,” room and home sensors that monitor health status, balancing aids, virtual and robotic electronic companions, and even drones.
In her lab, Dr. Hovakimyan has begun experimenting with small and large drones.
She refers to them as “Bibbidi Bobbidi Bots,” borrowing a phrase from the “Cinderella” movie, to make them seem less intimidating. Last month, in the Nicer Robotics laboratory at the University of Illinois, researchers began experimenting with an Oculus Rift virtual reality viewer to show people how it might feel to be close to a small drone. She believes that drones could ultimately be used to perform all manner of household chores, like reaching under a table to grab an object, cleaning chandeliers and weeding the lawn.
Many others are trying to devise solutions, as well. In a crowded four-room laboratory in South Seattle, the former Microsoft software designer and executive Tandy Trower is experimenting with a four-foot-tall rolling robot he calls Robby. With cameras, radar, microphone, speaker, a tablet interface and a movable tray, Robby may someday be able to serve as a mobile companion and even perform some light chores.
Mr. Trower said the robot, now a prototype in his Hoaloha Robotics laboratory, would be able to monitor the health of its human companion and assist with tasks like keeping track of medicines. Its screen could also be used for video conferences with physicians and other health care providers.
He said that the science-fiction future of elder-care robots is closer than many people believe.
“Rather than seeing the train in the distance, we’re seeing the light shining in our face right now,” he said.
Toyota Motor Corp. said last month that it would spend $1 billion to establish a new research laboratory adjacent to Stanford University to focus on artificial intelligence, underscoring the company’s view that it should be added to cars to make human drivers safer rather than to replace them. The hope is that such technologies will make it possible for aging people to drive safely longer.
“Driver assistance will turn cars into elder-care robots in a very positive sense,” said Rodney Brooks, a pioneering roboticist and a former director of the M.I.T. Computer Science and Artificial Intelligence Laboratory. “In the United States, when you can’t drive any longer, you’ve lost your independence.”
The need for such technology will grow sharply, given the broad demographic shifts sweeping through the world’s population.
An aging population will place enormous burdens on the world’s health care system by 2050, according to demographers. Already, for the first time in history, 14 percent of the world’s population is older than 65, a sharp contrast with the 9.1 percent of the population that is less than 5 years old.
Globally, the number of people 60 and over is expected to more than double by 2050 and triple by 2100. The number of people 80 and above is expected to double by 2050 and increase more than sevenfold by the end of the century.
