Meet the RoboThespian RT4 robot: a humanoid robot in a touchscreen kiosk that can interact with your visitors with gestures and audio. It has 24 DOF head and arms. It also comes 3 powered body axes. The robot can move its body, play songs, and do a whole lot more. You can load 10 minutes of custom content on it.
RoboThespian comes with a camera, an Asus Xtion IR depth sensor for motion tracking, and an open API. Not cheap though.
