Washington State University tests 'Robot Activity Support System' for elderly care (1/5)

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 in US robot activity support can ease the burden on US healthcare system to some extent.

The Robot Activity Support System, or RAS, uses sensors embedded 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.
