A robot video camera sent to investigate a mysterious, blocked door in Egypt?s Great Pyramid of Giza has found yet another door. With audiences in the U.K. watching on live television, the miniature robot crawled 71 yards up a narrow tunnel to explore a mysterious shaft blocked by a limestone door. It drilled a hole in the door and inserted a fiber optic camera. But the robot discovered that the chamber is blocked by yet another door?one that hasn’t been seen for more than 4,000 years.
Tim Kelly, of National Geographic’s television and film division, says, “I enjoyed the moment of discovery. We were not disappointed… we were successful in our mission.” It took National Geographic and the Boston firm iRobot a year to plan.
