These days, not everyone rocking the archeology game happens to be human. Recently a group of all-terrain robot rovers accompanied U.S. scientist John Rick down to Peru. There they explored the 3,000-year-old Chavin de Huantar temple where they made what some archeological authorities are calling “the most important discovery on this site in the last 50 years.”

The Chavin de what?

In case you’re not familiar with the Chavin de Huantar, it’s been called the “first major religious and pilgrimage center in South American history.” Clearly, the mega-temple was kind of a big deal back in the day and its ruins remain loaded with ancient artifacts and ruins.

It was constructed by the Chavins, a pre-Inca culture who apparently really loved to build. Construction on the site probably began around 1200 BC with new passageways added every 300 years or so. It remained a cultural hotspot until around 400-500 BC when it began its descent into history.

Enter Rick and his robots

Despite the fact that the site is a blatant archeological gold mine, few archaeologists have ever really gone all out as far as making a life’s work out of mining its ancient treasures. John Rick, however, is one of those rare few.

Due to the complex, narrow passageways located a the site, archeologists have no problem admitting that it holds tons of complex galleries that have yet to be discovered. That’s where Rick’s four-wheel drive robot buddies came in.

Builder burials grounds

As they were making their way through the passages, they recently came upon the graves of the Chavin guys who built the temple. The robots, who are all equipped with more photography equipment than some photography studios, lent a major hand in discovering the first burial sites of the Chavin period.

Among the things that Rick found interesting about the burials was that the workers not only appeared to be of lower classes but were buried face down under piles of rocks. Considering their not-so-respectful final resting places and the distinct possibility that they may have been sacrificed, it seems that the builders have only yet begun to reveal the secrets buried with them.
