Supposedly the first people to gain entrance to the Great Pyramid found strange things, what would be described as a robot today.
What is seen today is just the innards, originally was covered with smooth limestone. The joints were so finely put together the exact location of the entrance was not known. It hinged outward. That’s why the hole in the structure used as the entrance today, was bored into the side.
The first people to break into the Great Pyramid found nothing. They tunneled in because they could not find the actual entrance and were looking for gold on the orders of the Calif. Very disappointed, they were on finding the structure empty except for a stone sarcophagus. No gold, no jewels, no inscriptions, no robots.
