The Robot Sleuth and the Mexican Tunnel

The pyramids of Mexico's Teotihuacan have always been one of North America's archaeological treasures. But those and other remains of the ancient city have always been a mystery too. A door into Teotihuacan's shrouded past cracked open a little this year when an archaeological bot equipped with a camera was sent on a subterranean trek and found a 12-ft. wide corridor with a perfectly preserved arched roof that was built — and sealed — nearly two millennia ago. Archeologists are hopeful that it may be connected to the tomb of a high priest, a find that could reveal volumes about how the people who constructed the Mesoamerican metropolis once lived.
