A Robot Spider That Reads Your MindYou may find this spider robot somewhat creepy — but the good news is, the robot will know. The Hexapod robot tracks the faces of humans who interact with it, and registers their emotions. And responds accordingly. If you behave aggressively towards it, it'll back away. Or if you stare at it for a few moments, it'll upload your picture to its website. [Technovelgy]
