If you have a penchant for robotic projects, then the BotBrain Animatronic Robot Head Kit is a pretty good candidate. It is meant to help one pick up the basics of robotics and animatronics by leading the user through the entire assembly process of a fully functioning animatronic head. This head will be able to turn left and right, while moving eyes and eyelids add to the realism. The mouth can change according to how it is “feeling” at the moment, while integrated sensors enable it to react to changes in the environment. The BotBrain Animatronic Robot Head Kit retails for $449 so make sure you have a great love for all things robotic before dropping that amount of dough.
