Alibaba, RoboSense launch unmanned vehicle using solid-state LIDAR

The most important feature of the driverless delivery vehicle called G Plus is the solid-state LiDAR technology, the RS-LiDAR-M1Pre, developed by China’s RoboSense.

This is the first time that solid-state LiDAR has been  used in the development of an unmanned vehicle,clsim the companies,  heralding the beginning of  the solid-state LiDAR era in driverless vehicles.

RoboSense has reached a strategic partnership with Alibaba to provide delivery vehicles with solid-state LiDARs for all G Plus unmanned logistics vehicles.

The vehicles can be mass-produced, allowing the rapid expansion of unmanned logistics vehicles and streamlining mass market delivery logistics, for the rapid popularization of the vehicles.

The unmanned cars and trucks can also be equipped with different smart devices according to demand, turning the vehicle into a courier vehicle, a mobile self-pickup station, a mobile coffee vending cart, etc., which can be applied to various new retail scenarios.

The vehicle is equipped with three RS-LiDAR-M1Pres, two in the front and one in the rear, to ensure the most powerful 3D perception of the driving environment. This allows unmanned delivery vehicles to clearly see the direction of travel, including the shape, distance, azimuth, travel speed, and direction of travel of pedestrians, cars, trucks, and other obstacles, as well as the exact areas on which roads can be driven, etc., to ensure the smooth flow of unmanned logistics vehicles in a complex road environment.

The RS-LiDAR-M1Pre is the first MEMS solid-state LiDAR launched by RoboSense. The core technology of the MEMS solid-state LiDAR is disruptive to traditional mechanical multi-beam radars.

The MEMS micro mirror scanning scheme used in the RS-LiDAR-M1Pre requires only a few laser emitters and receivers to scan through the MEMS micro-mirror in both directions because of the swing angle. The resolution is a very fine, high angle and vertical angle resolution that reaches 0.2° throughout the angle of view.

In contrast, for traditional mechanical multi-beam LiDAR to achieve the same effect, they require more than a hundred laser transmitters and receivers to rotate and scan at the same time, which greatly increases material and human costs and reduces yield and reliability, making the advantages of MEMS solid-state LiDAR technology obvious.

While improving the performance of LiDAR, the cost savings is also great, and at the same time the miniaturization of the scanning structure greatly improves the stability of LiDAR.
