Abstract: An autonomous driving assembly for a vehicle includes a plurality of lidar units configured to be supported by a vehicle body. The lidar units are collectively configured to detect a periphery region in proximity to the vehicle body to aid in autonomous driving upon coupling the driving assembly to the vehicle body. Each of the plurality of lidar units has a field of view of less than about 180 degrees.

Abstract: Methods of route planning for a moveable device and associated systems are disclosed herein. In representative embodiments, the method includes (1) downsampling a 3-D point cloud generated by a distance-measurement component of the movable device to obtain a downsampled point cloud; (2) extracting ground points from the downsampled point cloud; (3) analyzing the ground points in a surface-detecting direction; and (4) identifying an object based at least in part on the downsampled point cloud and the ground points. The identified object and the ground points can be used for planning a route for the moveable device.

Abstract: The present disclosure provides an environment sensing system. The sensing system includes a laser detection module, the laser detection module including a first laser module, a second laser module, a third laser module, and a fourth laser module, a field of view (FOV) angle of each laser module being less than or equal to 120°. The first laser module and the second laser module are disposed on a front side of a movable platform to detect an area in front of the movable platform, the FOVs of the first laser module and the second laser module partially overlap. The third laser module and the fourth laser module are respectively disposed on both sides of the movable platform to detect a front left area and a front right area of the movable platform.
