Wondering what Japanese robots are up to these days? Find out at the Tokyo Skytree campus of Chiba Institute of Technology, which is actually just a couple of exhibition spaces located upstairs from the Skytree's shopping-mall complex. One area is devoted to robotics technology, with several interactive exhibits examining robotic vision and robot anatomy. The other half of the facility focuses on astronomy and space exploration, and features AR (augmented reality) games and a 300-inch 3D space theater. Admission is free.
