  In the past ten years, the use of 3D Time-of-Flight (ToF) LiDARs in mobile
robotics has grown rapidly. Based on our accumulation of relevant research,
this article systematically reviews and analyzes the use 3D ToF LiDARs in
research and industrial applications. The former includes object detection,
robot localization, long-term autonomy, LiDAR data processing under adverse
weather conditions, and sensor fusion. The latter encompasses service robots,
assisted and autonomous driving, and recent applications performed in response
to public health crises. We hope that our efforts can effectively provide
readers with relevant references and promote the deployment of existing mature
technologies in real-world systems.
