LEGO Technic vehicle rappels 22 meters down deep chasm cave.

Project Chasm Cave - Part II

On the slopes of Mt Hymmetos lay various caves and chasms. One of the most renowned is the Asteriou Monastery chasm cave, which consists of three chambers. The entrance to the first and largest chamber is a small crack in the rocks about 1.5 meters long and 0.5 meters wide. After this crack comes a sheer drop of more than 20 meters to the bottom of the chamber. After a first attempt to explore this cave, using a small mobile crane to lower a bright LED light and action camera through its entrance, I built a small remote-controlled vehicle that can rappel down the cave using a soft cotton belt. With the second stage of the exploration complete, the road is now open for further cave-exploration missions, using my rappelling system! Maybe landing a small tracked vehicle or crawler at the bottom of a deep cave. Who knows! Stay tuned for more and enjoy!
