At MainBot, we're creating meaningful robot companions, today for children, afterwards for the entire family, and ultimately later on for the elderly. We have the firm belief that robots will exponentially enrich our daily lives experiences. Our first robot, Winky, is a modular and intelligent robot companion for children ages 7-10 combining affective behavior and educational features. Winky is a tool through which children have their first engagement with the world of robotics, as its modular nature allows for plug & play modules to be attached or detached at any time via magnetic connection. Through an augmented reality app on the phone or tablet, a didactic presentation of the robot's structure is available to teach children the basics on how the robot works.
