Imagine a cat that can keep a person company, doesn't need a litter box and can remind an aging relative to take her medicine or help find her eyeglasses. That's the vision of toymaker Hasbro and scientists at Brown University, who have received a three-year, $1 million grant from the National Science Foundation to find ways to add artificial intelligence to Hasbro's "Joy for All" robotic cat . The cat, which has been on the market for two years, is aimed at seniors and meant to act as a "companion." It purrs and meows, and even appears to lick its paw and roll over to ask for a belly rub. The Brown-Hasbro project is aimed at developing additional capabilities for the cats to help older adults with simple tasks.
