Researchers have been using a special robot to explore tunnels below the ancient city of Teotihuacan.
The Tlaloc II-TC robot is particularly helpful for archaeological exploration as it can fit in to tight crawlspaces and send back a live video feed. Its mission for the team here was to enter a tunnel below the Temple of Quetzalcoatl and locate a hidden chamber concealed behind soil and debris. As the robot reached its destination however it came across something surprising - there wasn't one but three chambers located beneath the temple.
It is believed that the rooms below what is also sometimes referred to as the Temple of the Feathered Serpent would have been used by the rulers of Teotihuacan over 2,000 years ago and most likely served as a place where royal ceremonies and burials were carried out.
"A diminutive robot helped researchers make a substantial discovery during preliminary tests conducted in a tunnel running under the Temple of Quetzalcoatl at the archaeological site of Teotihuacan, the team said Monday."
