Archaeological teams from Egypt, Singapore, Britain and Hong Kong will send a robot inside the largest pyramid in Egypt in an attempt to discover what lies beyond two doors discovered in 2002.
At that time robots were sent down two narrow shafts leading away from the Queen's Chamber in both directions, but the robots were blocked after about 65m by "a stone wall or door" that had copper handles on it.
The robots drilled a hole and inserted a camera revealing a chamber with an inner door or wall opposite. It is hoped that the robots will be able to look beyond this barrier. Archaeologists hope to find clues to the final resting place of Cheops.
