A team of Japanese animators and engineers on Wednesday unveiled plans to build a moving 18-metre (60-foot) tall Gundam robot, in a nod to millions of science fiction fans. The Mobile Suit Gundam anime series first aired in Japan in 1979, and spin-offs featuring robots locked in intergalactic battles have won legions of enthusiastic fans in Asia, Europe and elsewhere. When I created Gundam 35 years ago, I used my imagination freely because it wasnt real, Yoshiyuki Tomino told reporters in Tokyo Wednesday.
