Meet Tlaloque and Tláloc II: two robots exploring a tunnel at Teotihuacán

At Teotihuacán, an ancient capital in the Valley of Mexico, robots have been employed to explore a newly-discovered tunnel leading from the Temple of the Plumed Serpent. One of the most exciting aspects of this tunnel is that, unlike other tunnels discovered in the past, this one had not been looted in antiquity. The tunnel apparently was sealed 1,800 years ago, leaving the treasures within protected.
