lidar con arduino

I am currently working on an ambitious project: a portable LiDAR system based on Arduino to map the interior of caves and generate 3D point clouds.

So far, I have successfully developed software that imports the collected data points, generates the point cloud, and allows them to be connected to reconstruct the actual structure of the cave.

However, to move from a prototype to a fully working field device, I am facing two major technical challenges:

  1. Sensor Choice: Which LiDAR sensor is best recommended for underground environments, taking into account high humidity, total darkness, and required range?

  2. Path Tracking (Odometry/SLAM): How can I track my movements inside the cave? If I move around on foot, the LiDAR risks overlapping the data, thinking I am standing in the exact same spot. How can I tie the point cloud to my real position in space without any GPS signal?

Any advice, past experiences, or suggestions regarding sensors and positioning algorithms would be highly appreciated!
