An autonomous car (also known as a driverless car, auto, self-driving car, robotic car) and Unmanned Ground Vehicle is a vehicle that is capable of sensing its environment and navigating without human input. 
Autonomous vehicles are usually powered by machine learning and neural networksa group or system of interconnected people or things., but can sometimes be pre programmed.
How does it work or a deeper look
Many such systems are evolving, but as of 2017 no cars permitted on public roads were fully autonomous. They all require a human at the wheel who must be ready to take control at any time.
Autonomous cars use a variety of techniques to detect their surroundings, such as radar, laser light, GPS, odometry and computer vision. Advanced control systems interpretUse knowledge and understanding to recognize trends and draw conclusions from given information. sensory information to identifyProvide an answer from a number of possibilities. Recognize and state briefly a distinguishing fact or feature. appropriate navigation paths, as well as obstacles and relevant signage. Autonomous cars must have control systems that are capable of analyzing sensory data to distinguishMake clear the differences between two or more concepts or items. between different cars on the road.
Throughout robotics competitions there are two sections. Remote controlled, and autonomous. The autonomous period of the tournament has robotics move around without any human input, only listening to their pre programmed commands.
