Secrets of Great Pyramid of Giza to be revealed by a robot

The 4,500-year-old secrets of the Great Pyramid of Giza's maze of hidden chambers are set to be revealed by an inflatable robot. Researchers are building a blimp-like probe that enters ancient monuments via a 3.5-centimetre (1.4-inch) 'keyhole' drilled through a wall. Once inflated inside the chamber, the drone flies like a blimp to explore inaccessible areas with minimal damage to artefacts or structures hidden within. Last month, a mysterious 30-metre (100ft) void nestled above the pyramid's Grand Gallery deep within the monument was discovered by an international team of researchers.

It is made up of two robots, a tubular machine equipped with a high definition camera and a probe that explores the structure via a small, inflatable blimp.
