This blog is about how Tesla's autopilot system works.

The autonomous vehicle that Elon Musk created with his team has become a big hit. Let's dig deeper into Tesla's self driving system to see how it works.

Autopilot:

Autopilot enables your car to steer, accelerate and brake automatically within its lane. Current autopilot features require active driver supervision and do not make the vehicle fully autonomous. There are a total of 8 cameras and 12 sensor spots on the car, all of them are used to assist and keep the driver safe.

The white dots are cameras and the red dots are sensor spots

Cameras :

Visual feedback is fed into the system via Tesla’s 8 onboard cameras. 3 of those cameras are situated on the wind screen and they are each used for different purposes. The first camera is the main camera which is calibrated to see up to 150 meters. The second one is a narrow field camera which has the capability to sense thing up to 250 meters away. The third one is a wide angle camera that can broadly see in a range of 50 meters. There are also 4 normal cameras 2 of those cameras are used for side view, blind spots, and maneuvering. Another 2 cameras are used for rearward and blind spots. The last camera is at the back of the car and can see as far as 50 meters, it also collects information from the environment.

Sensor Spots :

The car’s 12 sensor spots are like a cacoon being created around the car. Those sensor spots collect sensory input from as far as 8 meters away using the magic of ultrasound. The sensors help drivers with maintaining distance between cars and blind spot warnings. In addition to this there is a front facing radar that can detect objects up to 160 meters away by bouncing radio waves off of them, it is a key component in the sensory array.

Features :

Tesla’s cars detect stop sings, speed limits, pedestrians, trash cans, and other incoming traffic. The car has a high precision GPS which helps the computer detect the exact location of the car. Under the plastic bumper cover of the car is a radar that can look forward to a range of 700 meters using radio waves. Elon Musk’s marvelous designs makes Tesla cars learn and adapt to any situation. Its self driving chip is 260 square millimeters of prime samsung silicon which is filled with 6 billion transistors and is capable of performing about 26 trillion operations per second. The car can respond within just seconds with the help of a sensory array.

The world is changing into a fully electric place. Autonomous vehicles are getting smarter than ever. Who knows what will come in the future.
