Robotics expert Watanaru Yoshizaki demonstrates how to operate the arm of a giant "Kuratas" robot at an exhibition in Tokyo Nov 28, 2012. The four-meter-high, limited edition, made-to-order robot is controlled through a pilot in its cockpit, or via a smartphone. The four-tonne (4,000 kg) "Kuratas" can be customised in 16 different colours, and is armed with a futuristic weapons system, including a multi-rocket launcher that fires plastic rockets filled with compressed water.
