This news talks about a robot who plays a rock-paper-scissors game and never loses.

This robot was developed by a group of Japanese scientists in the Univeristy of Tokyo in 2012. The name of this robot is Janken and it use high-speed recognition and reaction, rather than predicction, that's why Janken wins every time. 

The robot can recognize in only one millisecond what shape has the human hand and prepare an immediate movement to win the game. 

My opinion about this robot it's a good example of the hard work in the scientist world. It's incredible what the scientist world can do...Now they have invited a fabulous robot cheat that has never lost any game, and it reacts in one millisecond this is fantastic. I think that we have to keep working hard and do big things, because today we do incredibly little things but tomorrow we can do big things with the theroy that we learn when we do little things.
