(Antonio Calanni/AP) A video technician works on one of the unmanned, electric-powered orange vans that will leave Italy July 20, 2010, and are equipped with laser scanners and video cameras that work in concert to detect and help avoid obstacles. The vehicles will brave the traffic of Moscow, the intense summer heat of Siberia and the bitter cold of the Gobi desert before the planned arrival in Shanghai at the end of October.
