Does the Pyramid of Cheops hide more secrets within its massive volume? A 1992 robot explored one tiny passage only to be blocked by limestone doors with brass handles — and the next one drilled through only to find anther door behind it.
Built 4,500 years ago, the vast tomb contains several passageways and two rooms, the Kings's and Queen's Chambers. Two shafts extend from each, but whereas those from the King's Chamber reach the exterior, those from the Queen's Chamber stop dead deep within the monument.
A new robot, being prepared by a team from Leeds University, is designed to be able to drill a large enough hole for itself to pass through the doors. No word on what they hope to find on the other side.
