Now that we have learned the four technologies associated with the eye of a self-driving car, let’s take a look into the robotics. If the above technologies are the eyes of the car then the robotics are the arms and legs. The name of the robotics device in the self-driving
car is the actuator. The actuator is able to translate an electrical signal into a physical action. The actuator is able to operate with the help of a motor. The motor inside of this device rotates based on the signal that it receives. Due to the complexity of a self-driving car, these devices come with many actuators. These actuators are installed in the steering wheel, brakes, gears, engines, and more.
