    Abstract: Embodiments of the disclosure provide a LiDAR assembly. The LiDAR assembly includes a central LiDAR device configured to detect an object at or beyond a first predetermined distance from the LiDAR system and an even number of multiple auxiliary LiDAR devices configured to detect an object at or within a second predetermined distance from the LiDAR system. The LiDAR assembly also includes a mounting apparatus configured to mount the central and auxiliary LiDAR devices. Each of the central and auxiliary LiDAR devices is mounted to the mounting apparatus via a mounting surface. A first mounting surface between the central LiDAR device and the mounting apparatus has an angle with a second mounting surface between one of the auxiliary LiDAR devices and the mounting apparatus.
