Google's unmanned subsidiary, Waymo, has successfully developed all of the internal unmanned sensor hardware required by its own unmanned vehicle, leading a number of rivals such as Uber. This is a big turning point in the company that Sensor will significantly reduce the manufacturing costs of autopilot vehicles. And manufacturing costs is the automatic driving car production a big bottleneck.

  Waymo declined to disclose the cost of its latest hardware, but the company revealed one of the components - a radar array using a laser three-dimensional capture object (ie, LiDAR sensor), whose price dropped from $ 75,000 to less than one-tenth of the present. A sensor is a detection device that can sense the information being measured and can convert the Suction Control Valve  sensed information into electrical signals or other desired forms of information output by a certain law. In layman's terms, the sensor can be said to be 'one of the unmanned vehicles.'

 Google research and development of unmanned vehicles using intelligent software and sensing equipment, to be able to perceive all the surroundings of the car and simulate the human to make judgments: roof with a laser radar rotary sensor, can scan the radius of about 70 meters within the environment; Of the sensor with a location assessment function; car computer through the rearview mirror near the camera 'read' traffic lights, identify sidewalks and obstacles and so on. Another four standard automatic radar sensors are located in the front and rear, helping to determine the distance between the body and the fuel metering valve obstacles. These vehicles are safer than people driving cars because they react more quickly and effectively.

  Although known as 'unmanned', but still need a driver sitting in the steering wheel after the 'alternate' in the emergency operation of the manual.
