The Caveatron is a unique compact, handheld, electronic device for mapping caves or other underground environments. It functions as a cave survey tool, recording conventional distance, azimuth and inclination measurements and can also go far beyond that with its integrated LIDAR to capture a full 3D scan of the cave interior. It greatly speeds up the cave survey process by recording station-to-station shots in just a few seconds and performs a station-to-station 3D scan traverse in less than a minute. The user can fully interact with the device and review data with the built-in touchscreen. A USB port provides access to the stored data from a PC or Mac and is also used to charge the integrated long-life battery pack. The station measurement file is compatible with Walls Cave Mapping Software and the LIDAR scan file can be quickly processed into a standard point cloud with custom-written software. The Caveatron is designed to be easily portable, lightweight, and low cost as well as water and dirt resistant and durable enough to survive regular use in a cave.
The design has recently been updated with a faster processor, enabling 4 times the scan resolution, an enhanced IMU for better position accuracy, easier data transfer, and other new features. The enclosure is now a bit smaller, more waterproof, uses a custom printed circuit board, and can be fully 3D printed.
