An autonomous car,also known as a driverless car,self-driving car,or robotic car
is an autonomous vehicle capable of fulfilling the transportation capabilities of a traditional
car. As an autonomous vehicle, it is capable of sensing its environment and navigating without
human input. Robotic cars exist mainly as prototypes and demonstration systems. As of 2014, the
only self-driving vehicles that are commercially available are open-air shuttles for pedestrian
zones that operate at 12.5 miles per hour (20.1 km/h).

Autonomous vehicles sense their surroundings with such techniques as radar, lidar, GPS, and
computer vision. Advanced control systems interpret sensory information to identify appropriate
navigation paths, as well as obstacles and relevant signage.By definition, autonomous
vehicles are capable of updating their maps based on sensory input, allowing the vehicles to keep
track of their position even when conditions change or when they enter uncharted environments.

Some demonstrative systems, precursory to autonomous cars, date back to the 1920s and 30s.The
first self-sufficient and truly autonomous cars appeared in the 1980s, with Carnegie Mellon
University's Navlab and ALV projects in 1984 and Mercedes-Benz and Bundeswehr
University Munich's EUREKA Prometheus Project in 1987. Since then, numerous major companies
and research organizations have developed working prototype autonomous vehicles, including
Mercedes-Benz, General Motors, Continental Automotive Systems, Autoliv Inc., Bosch, Nissan,
Toyota, Audi, Volvo, Vislab from University of Parma, Oxford University and Google.In July 2013, Vislab demonstrated BRAiVE, a vehicle that moved autonomously on a mixed traffic route open to public traffic.As of 2013, four U.S. states have passed laws permitting autonomous cars: Nevada, Florida, California, and Michigan.In Europe, cities in Belgium, France, Italy and the UK are planning to operate transport systems for driverless cars,and Germany,the Netherlands, and Spain have allowed testing robotic cars in traffic.
