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. As a first step to exploring this cave, I designed and built a small mobile crane to lower a bright LED light and action camera through its entrance. The second step will be to design a bigger crane capable of lowering a small and lightweight vehicle to further explore the first chamber of that cave! Stay tuned for more and enjoy!
