A driverless van has completed the longest-ever trip by an unmanned vehicle, beginning in Italy and arriving in China, covering 13,000 kilometers (8,077 miles), researchers said.

The van arrived at the Shanghai World Expo on Thursday, after leaving Italy on July 20.

The three-month trip took the van through Eastern Europe, Russia and Kazakhstan; across China through the Gobi Desert; and finally along the Great Wall, before arriving for a celebration at the expo. The driverless van relied solely on electricity.
