Introduction
The Google Self-Driving Car is a project by Google that involves developing technology for autonomous cars, mainly electric cars.
The project is currently being led by Google engineer Sebastastian Thrun.
Technology
Google's robotic cars have about $150,000 in equipment including a $70,000 LIDAR system.
This laser allows the vehicle to generate a detailed 3D map of its environment.
What is it?
It is the first truly driverless electric car prototype built by Google .
It is with two seats and room enough for a small amount of luggage.
How does it work?
Powered by an electric motor, the car uses a combination of sensors and software to locate itself in the real world combined with highly accurate digital maps.
A GPS is used, to get a rough location of the car, at which point radar, lasers and cameras take over to monitor the world around the car, 360-degrees.
The software can recognise objects, people, cars, road marking, signs and traffic lights, obeying the rules of the road.
Equipment used
Lidar System
Video Cameras
Radar Sensors
Ultrasonic Sensors
Orientation Sensors
Central Computer
Lidar
The Velodyne HDL-64E lidar sensor is designed for obstacle detection and navigation of autonomous ground vehicles.
Video cameras
Detect traffic lights, read road signs, keep track of the position of other vehicles and look out for pedestrains and obstacles on the road.
Radar sensors
Four standard automative radar sensors, three in front and one in the rear which helps in determining the position of distant objects
Ultrasonic sensors
It is used to measure the position of objects very close to the vehicle, such as curbs and other vehicles when parking.
Advantages
Relieving vehicle occupants from driving allowing them to concentrate on other tasks or to rest during their journeys.
To avoid accidents .
Increasing roadway capacity by reducing the distances between cars.
The current location of vehicle can be determined using global positioning system (g.p.s) .
Seat belts are provided.
