Titan the "robot" was presented at Gitex Technology Week and it impressed quite some people. I watched the videos showing it and at first I too was amazed by the giant. Only later did I realize that the "robot" was nothing more than a guy in a plastic suit. There are minor details that give it away. Firstly, its arms are connected to it's ribs and it never moves its shoulders. Then, its feet are way too small to have ever been able to sustain the weight of a real machinery. If you look carefully you can see the man's hands controlling everything. The "mirror" on the robot's chest is actually a means for the human inside to see. The whole prank is so well planned that even Engadget were fooled, or so they want us to believe.
