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.
The vehicle weathered three months of rain, blizzards and sun, and arrived in Shanghai with no major problems, according to researchers tracking its progress. The van even stopped to pick up hitchhikers outside of Moscow.
"We are really happy. It's a real milestone in our field of vehicular robotics," said lead researcher Alberto Broggi.
The van, designed by Italian tech company Vislab, featured 12 refined sensors, including cameras, a carbon dioxide sensor, a GPS device and an off-road laser scanner.
"This driverless trip to China shows how science can capture people's imagination through achievements that would recently have been unthinkable ... [and] provide major environmental and economic benefits," said Maire Geoghegan-Quinn, head of research, innovation and science for the European Commission.
The record-setting journey comes in amid of major developments in driverless vehicle technology.
Earlier this month, Google announced that its self-driving vehicle had successfully traveled about 350 miles [563 kilometers] from its headquarters in Mountain View, California, to Santa Monica, California. Google, which engages in energy-related businesses along with its core Internet search-engine service, says its self-driving cars have logged more than 140,000 miles. General Motors, Volkswagen and Stanford University are also developing driverless vehicles.
No maps were used as Vislab's van traveled from Italy, then off-road through much of Siberia and China. The van topped out at 37 miles per hour and traveled about four hours a day to allow for adequate battery recharging.
As for human intervention during the van's three-month journey, "We had to intervene manually only on limited occasions, such as in the Moscow traffic jams and when passing toll stations," said lead researcher Broggi, who also is a professor at Italy's University of Parma.
