From national.co.uk they send us an interactive infographic with 10 technologies used in Google's autonomous car, a work that shows a description of them indicating the place where each of the sensors used is located.
We leave you here with a description of the most striking:
– Rotating upper chamber: The heart of the car, a camera with 64 laser beams that creates 3D images of objects around the vehicle, calculating the distance of each obstacle within a radius of 200 meters. Camera mounted on the windshield: To see objects just in front of the car, especially pedestrians and other cars. This camera also detects and records information about traffic signals and traffic lights, which is interpreted with the built-in software. 4 radars on the bumpers: Radars at the front and rear to detect other vehicles. The software is programmed to maintain a distance of 2-4 seconds (calculating distance and speeds), so it will automatically accelerate or decrease speed depending on the environment. Antenna at the rear: Receive information on the precise location of the car using the GPS satellites. To reduce interference, they are compared with data from other sensors, always updating the vehicle's internal map. Ultrasonic sensor: Installed on one of the rear wheels, it helps to track the movements of the car and alert the vehicle to obstacles in the rear. They are sensors that are already used in some current cars to help park in tight places. Indoor sensors: There are altimeters, gyros, and tachometers inside the car, sensors that help determine the position of the vehicle. CPU: All the data collected by these sensors is gathered and interpreted with your CPU, using software specially designed for it.
