A small robot has uncovered three 2,000-year-old chambers under an ancient temple in Mexico, archaeologists from the National Anthropology and History Institute announced this week.
The robot, named Tlaloc II-TC after Mexico's ancient god of rain, found the chambers under the Temple of the Feathered Serpent (also called the Temple of Quetzalcoatl) in the Mesoamerican ruins of Teotihuacan, which is just 30 miles from Mexico City. The ancient city, thought to have been established around 100 BC, had more than 100,000 inhabitants at its peak, but had long been abandoned before the Aztecs arrived in the 1300s.
In the 1980s, the remains of over 200 warriors were found in the core of the Temple of the Serpent. Archaeologists found a tunnel under the same temple in 2011 using radar technology. They then deployed the remote-controlled robot, which is equipped with an infrared camera and a scanner that generates detailed maps of the chambers beneath the temple. Three feet long, it can squeeze into tight spaces where a person would otherwise be unable to explore.
