Robot explores a tunnel at Teotihuacan

The current investigators of the tunnel (or man-made cave) that was found below the Temple of the Feathered Serpent in late 2003 has sent in a small car-robot called Tlaloque I (named after the helpers of the rain god Tlaloc). The robot has obtained footage of the first meters of the tunnel that was sealed 1,800 years ago. This is the first time a robot has been used in archaeological research in Mexico (a similar device has been used in Egypt). The tunnel appears to be stable enough for archaeologists to enter in the near future.

Earlier investigations with ground penetrating radar have detected that the roughly 100 m long, 2.5 m high and 4 m wide tunnel leads to three chambers. The tunnel is filled with dirt and stone but the robot could run for a short distance in a small space located in between the fill and the vaulted ceiling.
