The Google driverless car is a project by Google that involves developing technology for autonomous cars. The software powering Google's cars is called Google Chauffeur. Lettering on the side of each car identifies it as a "self-driving car."The project is currently being led by Google engineer Sebastian Thrun, director of the Stanford Artificial Intelligence Laboratory and co-inventor of Google Street View.
Thrun's team at Stanford created the robotic vehicle Stanley which won the 2005 DARPA Grand Challenge and its US$2 million prize from the United States Department of Defense.
The team developing the system consisted of 15 engineers working for Google, including Chris Urmson, Mike Montemerlo, and Anthony Levandowski who had worked on the DARPA Grand and Urban Challenges
The U.S. state of Nevada passed a law on June 29, 2011 permitting the operation of autonomous cars in Nevada. Google had been lobbying for robotic car laws. The Nevada law went into effect on March 1, 2012, and the Nevada Department of Motor Vehicles issued the first license for an autonomous car in May 2012.
Google's robotic cars have about $150,000 in equipment including a $70,000 LIDAR (laser radar) system. The range finder mounted on the top is a Velodyne 64-beam laser. This laser allows the vehicle to generate a detailed 3D map of its environment. The car then takes these generated maps and combines them with high-resolution maps of the world, producing different types of data models that allow it to drive itself.
The license was issued to a Toyota Prius modified with Google's experimental driverless technology. As of April 2012, Florida became the second state to allow the testing of autonomous cars on public roads. California became the third state to legalize the use of self-driven cars for testing purposes as of September 2012 when Governor Jerry Brown signed the bill into law at Google HQ in Mountain View
In August 2011, a human-controlled Google driverless car was involved in a crash near Google headquarters in Mountain View, CA. Google has stated that the car was being driven manually at the time of the accident. A previous incident involved a Google driverless car being rear-ended while stopped at a traffic light.
In August 2012, the team announced that they have completed over 300,000 autonomous-driving miles (500 000 km) accident-free, typically have about a dozen cars on the road at any given time, and are starting to test them with single drivers instead of in pairs.
Four U.S. states have passed laws permitting autonomous cars as of December 2013: Nevada, Florida, California, and Michigan. A law proposed in Texas would establish criteria for allowing "autonomous motor vehicles".
