Mexico City, Apr 16 (EFE).- A robot will soon begin exploring the last stretch of a tunnel found at the archaeological site of Teotihuacan in central Mexico, the third time anywhere in the world that such an automaton is used to design excavation strategies.
The tunnel, discovered under the Temple of the Plumed Serpent, or Quetzalcoatl, is believed to lead to a chamber almost 2,000 years old, probably a place where dignitaries of the pre-Columbian city received their investiture or were buried, the National Anthropology and History Institute, or INAH, said.
