Check out this cool Ganzbot that can talk. The Ganzbot can also read Twitter posts and show emotion.
This funny little robot has eyes, eyebrows and a mouth and will verbally read your latest Twitter status to you. It uses an Arduino Decima to control the head actions and receives the latest Twitter status information over USB from a host computer.
For those who don’t know, Twitter is a micro blogging tool where users announce what they’re doing with 140 characters or less. You can also send the robot something to say directly from the command line with a few Ganzbot moods to choose from.
