Several small robots suited with a camera helped archaeologists discover three new tunnels with remains that could be as 3,000 years old in a temple in Chavin de Huantar.
According to information from Channel News Asia these passageways hold ceramics, tools and human remains.
“The robots, remote-controlled all-terrain vehicles carrying lights and cameras, were designed by engineers at the University of Stanford and helped explore narrow passageways at the ancient site”, informed this media, who cited Peru’s minister of culture.
One of these tunnels contained the remains of three people and one of them appeared to have been sacrificed.
Channel News Asia says that Chavin de Huantar was once a religious and administrative center for people who were crossing the Andes. It was designated a UNESCO World Heritage Site in 1985.
