It would be very interesting to go on somewhere and you don’t have to drive, just enjoy. The driver-less car, or self-driving car, or robotic car or unmanned ground vehicle is a vehicle capable of motion by sensing its environment and navigating without human interaction. Currently, this technology is under research. Major companies like Waymo, a subsidiary of Google, general motors and Audi are testing the unmanned cars now. The first prototype of unmanned car was seen in 1980s in Carnegie Melion University’s Nvlab and ALV project in 1984. The autonomous cars are equipped with emergency braking, backup cameras, adaptive cruise control and self-parking systems. Google announced its autonomous car project in 2008. The distance between the car and objects surrounding the car is accurately determined using a 3-D map and bouncing the laser beams.
This technology is referred as Laser Illuminating Detection and Ranging (LIDAR). It also the give information about the profile of the objects surrounding the car. Google caruses a Velodyne 64-beam processor that gives a 360 degree view. To measure the speed of surrounding objects RADAR technology is used.
The 4 bumper mounted Radar, 2 in front and 2 in back bumper that enables the car to make smart decisions to avoid collision with other on the road. The millions of data are analyzed to predict what the object is. The high definition camera that gives the view of surrounding, every frame per second of it is analyzed which is made up of thousands of pixels are analyzed using the artificial neural network. Each time data is analyzed and processed while travelling in real time to find solutions of every possible situations. Such as, a slow moving car vehicle in the right of your car suggests to move left.
8 Tesla, developed by Elon Musk, another driverless car uses a technology similar to aviation autopilot technology for automation. It uses camera technology for computer vision.3 BENEFITS OF DRIVERLESS CARS-· This technology would help to reduce the accidents that happens every year caused by humans.· Humans usually sleep, talk, and drink while driving which is impossible for these cars.· The limited speed of these cars would ultimately reduce accidents due to rash driving.· The machine takes the driving responsibility, in the meantime human can do another important work.· These are light-weighted and can reduce traffic also.· Efficient travelling thus reduces the fuel costs and fatigueless.
DISADVANTAGES OF DRIVERLESS CARS-· It will eliminate the transportation jobs.· These cars are not suitable for every climatic situations. During heavy rainfall car may get damaged or stop functioning properly.· It would affect the industries based on petroleum and diesel.· It can be hacked and thus affects the vehicle’s control operation.
