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 (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 robo
