Scientists have created a robot that could help elderly people with dementia and other limitations live independently in their own homes.
The Robot Activity Support System, or RAS, developed by the Washington State University (WSU), uses sensors embedded in a 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.
