If you’re a parent, you probably know how expensive hiring a nanny can be. To help out, companies are coming out with high-tech alternatives. Beta robot is a roving robot that roams around the home to assist with tasks such as waking up the kids when it’s time to get ready for school, telling bedtime stories, and singing the children’s favorite songs. When parents are not home, they can view their children through the robot’s built-in cameras, which they can monitor via a mobile app.
