The Chinese eye on the drone may have introduced a voice coil motor. 5g, AI, self driving, and 3D printing are twenty-one of the most popular technologies of the 20th century, with autonomous driving, for example, in addition to well known car brands such as BMW and Audi Baidu, Google, Amazon, Alibaba and other well-known search engines, e-commerce companies have also committed to the technology. 

     The goal of autonomous driving is to free our limbs, and the success of this technology depends on a crucial component, here, Voice Coil Motor, you've got three minutes, you're free to take a guess, yes, that's right, it's Lidar. Like the eyes of a self-driving car, Lidar has a wide field of vision that allows it to scan quickly and then focus on the subject. To some extent, the race to win the autopilot race will depend on who develops lidar first. 

     The exciting news from voice coil motor is that more than half of the more than 60 self driving companies in Silicon Valley licensed to test driverless cars are clients of a Chinese company, hopesay technologies. HESAI's laser radar Pandar series has been approved by 42 cities and regions in 18 regions. 

     When it comes to Lidar, it measures the distance of a distant object by sending out a laser beam and receiving the light reflected from a distant object. However, laser beams are very narrow and they do not scatter, so a single lidar pulse can only sense a very small object. For practical use, the Lidar Sensor has to be scanned in some form. Most Lidar sensors are connected to a drive motor that rotates them, and once the laser is synchronized with the motor's motion, we can tell where the laser is pointing and combine the whole image of the environment ahead. Therefore, the field of view of a lidar depends on the angle of rotation of the motor, which has been used in voice coil motors.

    Kunshan Tong Mao Electronics Co. , Ltd. . Deep tillage voice coil motor field for many years, with European and American advanced industry technical experience, customer demand-oriented design, professional customized for customers with reasonable performance voice coil motor, now, the tongmao voice coil motor has been used in Lidar.
