How robot explorers are making the finds of the future

Gone are the days when archaeology was just a whole load of sand, dust and bones. These days the real explorers are all about the robotics. As technology has progressed, archaeological tools have become more sophisticated, including the potential to undertake scientific investigation with zero disturbances of the surrounding material. With the use of "non-invasive archeology" amazing discoveries can be made, such as the recent ground penetrating survey that appeared to indicate Shakespeare's skull might not be in his tomb. While these developments are all very useful, non-invasive technologies cannot, and never will, provide perfect resolution of the features within hidden spaces.
