Meet Wakamaru, the Linux-powered humanoid robot

Meet Wakamaru, the Linux-powered humanoid robot: "Wakamaru features continuous access to the Internet and comes equipped with voice and face recognition capabilities that allow the robot to search for and follow voices, faces, and movements. It has the ability to comprehend and interact with humans (such as discussing daily news it obtains via the Internet) based on a built-in dictionary and voice recognition, and can be programmed to call or email a designated person, a hospital or security firm if it notices a problem. When connecting remotely to Wakamaru via its built-in camera-equipped mobile phone, users can see images of the house the robot serves and even communicate with family members at home."
