MOSCOW – It was second time lucky on Tuesday as an unmanned spacecraft carrying Russia's first humanoid robot docked at the International Space Station following a failed attempt over the weekend. Am ready to carry on with work," the robot's Twitter account said in a jokey first tweet from space. Copying human movements and designed to help with high-risk tasks, the life-size robot, Fedor, is due to stay on the ISS until Sept. 7. Speaking to Russian cosmonauts on the ISS via a video link-up, President Vladimir Putin lavished praise on them for the way they handled the glitch. The problems with docking were "in some way abnormal," he said, adding that "as usual for our cosmonauts, you dealt with this work magnificently. The robot sat in the commander's seat of an unmanned Soyuz spaceship that blasted off Thursday from a Russian spaceport in southern Kazakhstan.
