Meet Professor Einstein: a cute talking, walking robot with built-in WiFi, expressions, and gestures that lets you play brain-teasing games and teaches a thing or two about science. It recognizes speech and can talk about the weather, math, and other issues. It has cloud-based interactive apps.
Professor Einstein has a rechargeable battery that lasts up to 3 hours. It combines with your iPad or Android tablet to provide a rich learning experience to students. The Stein-O-Matic app serves as the controller for this system. You can find this cool robot on Kickstarter.
