"Apparently, Mexico is the place to be if you're a laser-equipped robot with 3D scanning on the brain. Just 11 months after the DepthX robotic submarine mapped the El Zacat&amp;oacute;n Cenote, the 3D-R1 has managed to collect over 5GB of map data in 3.5 days which was then used to create a \"comprehensive 3D plan of the underground mining operation.\" The mine in question was the San Jose silver mine in Mexico, and while on duty, the robot scooted across some 2.2-kilometers of underground drives and access ramps in order to conduct over 240 total scans. There's no word on whether the mechanical creature is scheduled to map out any other nooks and crannies around the world, but given the accuracy exhibited in this run-through, we don't foresee it taking any kind of extended vacation.[Via Robots]"^^<http://www.w3.org/2001/XMLSchema#string>
