A robot created by Washington State
University (WSU) scientists could help elderly people with dementia (痴呆) and other limitations live
independently in their own homes.
The Robot Activity Support System or
RAS, uses sensors installed in a WSU smart home to determine where its
residents are, what they are doing and when they need assistance with daily
activities. It navigates (定位) through rooms and around obstacles to
find people on its own, provides video instructions on how to do simple tasks
and can even lead its owner to objects like their medication or a snack in the
kitchen.
"RAS
combines the convenience of a mobile robot with the activity detection
technology of a WSU smart home to provide assistance in the moment, as the need
for help is detected," said Bryan Minor, a postdoctoral researcher in the
WSU School of Electrical Engineering and Computer Science.
Currently, an estimated 50 percent of
adults over the age of 85 need assistance with every day activities such as
preparing meals and taking medication and the annual cost for this assistance
in the US is nearly $2 trillion. With the number of adults over 85 expected to
triple by 2050, researchers hope that technologies like RAS and the WSU smart
home will relieve some of the financial strain on the healthcare system by
making it easier for older adults to live alone.
RAS is the first robot researchers have
tried to incorporate into their smart home environment. They recently published
a study in the journal Cognitive Systems Research that demonstrates how RAS
could make life easier for older adults struggling to live independently.
"While we are still in an early
stage of development, our initial results with RAS have been promising,"
Minor said. "The next step in the research will be to test RAS'
performance with a group of older adults to get a better idea of what prompts,
video reminders and other preferences they have regarding the robot."

C . Optimistic.
D . Uncertain.
（4）What can be a suitable title for the text?
A . Elderly people leave the nursing home.
B . Smart Home Tests first elder-Care robot.
C . RAS, the first robot to make home smart.
D . Older adults have benefited from RAS.
